“Total-Bond” Mosaic

Domestic

Mosaic parquet is very suitable for use in the indoor areas of both domestic and commercial buildings alike.

The extensive range of patterns and designs in “Total Bond” Mosaic allows the client/specifier to select a specie of timber and a chosen pattern to suit any mood. “Feature strips” and/or “Feature Borders” may also be introduced to suit individual taste and as a complement to any the decor.

In domestic homes, Mosaic Parquet with regular care and maintenance, will last very many years, if not the life of the home. Being of solid natural timber, Parquet is not suitable for external use nor for use in wet areas such as bathrooms or laundries. However, there is not a home that should not have, a Parquet Floor!

Commercial

 

Commercially, “Total Bond” Wood Mosaic opens an almost limitless range of possibilities for use.

It is ideal for Shopping Centres, Dance Floors, Motor Vehicle and similar Showrooms, Offices, Shops, Schools, Colleges, Play Centres, Child Minding, Handicapped Children’s Areas, Banks, Theatres, Restaurants and Universities. It is of course the playing surface for our range of “AIR-THRUST” Pneumatic Sports Hall Floor Systems.

“Total Bond” Wood Mosaic can be treated with a wide range of surface finishes which provide minimum maintenanceand exceptional longevity. When used commercially, it is wise to install mat wells, fitted with Electrostatic Dust Control Mats immediately inside external doorways. This simple precaution prevents mud and slush being walked into the building and onto parquet, treatment which does not enhance the appearance of any floor. The inclusion of these sometimes “insignificant” items does much to provide facilities that are “well designed” to cater for years of wear and tear, minimum maintenance and retain handsome natural beauty.

Special Thicknesses

While “Total Bond” Mosaic is produced in a standard 9 mm thickness, 19mm is also available for use in Shopping Malls, Motor Showrooms or other specialist applications.

”Perfection” - Side Grain, Square MilledWood Block Parquet

Wood Block Parquet is the more “traditional” form of the product. As such, each block is individually laid into the floor, making each floor matrix a completely Hand Crafted Installation. Advancement in adhesive technology allows this product to be installed without the need of interlocking tongues and grooves, giving greatly increased wear life to the floor. The 19 mm thickness of this product provides for lifetime wear of this floor in Domestic and Light Commercial applications.

Domestically

Domestically, it enables the client to select patterns and designs which are limited only by one’s own imagination. “Feature Border” work is often a hallmark in Wood Block Installations, which sets these floors apart from any other as being creatively Distinctive, Elegant, Natural and a reflection of one’s Personal taste. Wood Block Flooring allows one to create highly distinctive Feature Flooring that may be “quiet and subtle” or “bright and vibrant”, according to your selection of timbers and patterns. You may create what you will, but you will still retain the handsome, natural charm that only Wood - Natural, Beautiful, Earthy Wood can impart.

Commercially

Commercially, “Perfection” Wood Block is especially suitable for use in Clubs, Hotels, Civic Centres, Town Halls, Hospitals, Banks, Libraries, Theatres, Restaurants, Universities, Recording Studios and Churches.

Many of the World’s great hotels feature Wood Block flooring in Reception areas, Ballroom and Dance Floors. span style=font-size: medium;span lang=font-family: Times New Roman;en-AUen-AUThe 19mm thickness of this product makes it extremely stable and long wearing, qualities which are important when considering the use that some of these floors are to withstand. The handsome, natural character of the product does much to create atmosphere. It’s thickness is consistent with that of carpet and under felt to ensure consistent levels.

 

Wood Block is exceptionally well suited for Light Industrial use in Clothing Factories, Light Engineering Works, Motor Vehicle and other Showrooms. It is particularly well suited for use in Schools and Colleges, Offices, Shops and Shopping Malls. As with all our products “Perfection” Wood Block can be treated with a wide range of surface finishes that will provide for minimum maintenanceand long life.

“Perfection” - Side Grain, Tongue & Grooved, End Matched, Wood Block Parquet

“Perfection”Side Grain, Tongue & Grooved, End Matched, Wood Block Parquet flooring can be used anywhere that Square Milled material would otherwise be used.

The basic difference between Tongue and Grooved End Matched material and its Square Milled counterpart, is that the former has been used for centuries by installation with Hot Bituminous Mastic, prior to the advent of more sophisticated adhesives. Sections of the European market still prefer Tongue & Grooved product.

Due to the fact that bleeding of the bitumen would occur if a Tongue and Groove were not used, this product must necessarily have its interlocking method of connection. This system of flooring, however, has benefits to offer over and above the Square Milled Design.

Firstly, extensive research by experts in the field has described this system as the most preferred form of flooring for Electrical Workshops, Schools of Electrical Engineering, County Council Workshops, Welding Bays and areas throughout industry where high voltage electric tools and machineryare being used.

 The thermal insulationas well as the electrical insulationof 

a)         The bed of Bituminous Mastic and 

b)         The solid timber Wood Block, provides a high degree of safety in areas where “mistakes can be fatal”.

End Grain “Perfection ”

- Wood Block Parquetry Decoratively

 

End Grain may be used decoratively wherever one wants to create an environment that projects boldness and strength. End Grain definitely establishes that “air of distinction”. Even to the uninitiated, End Grain Wood Block is a superbly handsome creation. The warmth and depth of this product really has to be seen to be appreciated.

Whether in your home or in the foyer of the Hilton - end grain wood block will create an outstanding impression with your associates and silently portrays the character of a discerning choice.

Industrially

“End Grain”- Heavy Duty Wood Blockflooring may be used wherever machines, equipment and/or manufacturing processes damage the floor, or where extreme traffic is encountered.

This product is meant to take heaps of abuse. From Government Printing Offices to bulldozer/heavy machinery manufacturers, oils, grease and heavy equipment can subject this style of floor to extreme abuse.

Of prime importance is the fact that the “End Grain” of the product shows almost negligible wear, even after years and years of traffic weighing many tons. This fact is important for more reasons that might be obvious.

Those who have ever seen a factory or warehouse with heavy forklift or pallet truck movement know just how much concrete and similar floors wear (even when supposedly “treated” or “coated”. It is however, grit and concrete dust that plays such havoc with the working parts of tremendously expensive machines. The result of such wear can be devastating.

What’s more the operating costs of the business, the all-up cost of replacing parts and the down-time on production machines is enormous. The utilisation of this style of heavy duty Wood Block provides excellent traction, excellent absorption of oils, grease, inks and dirt, and where sever damage occurs to a block, it is a simple matter to remove and replace same.

By comparison with an “End Grain” Wood Block Floor, a concrete floor given severe punishment can soon look like the surface of the moon with grit, dust and missing sections of concrete being picked up by traffic and transferred to the working parts of valuable machinery.

Why select – Parquet ?

 

The warmth and natural beauty of our wide range of prized Australian and selected South Pacific hardwood timbers can be used to compliment any decor whilst adding that noble touch of luxury to your living.

You can completely transform any room in your home to a room of function and great beauty to the admiration of all your friends - simply by installing one of our hand crafted floors.

You may wish to create a rugged Spanish atmosphere among timber beams, exposed brickwork and metal work or just present the quiet evidence of distinctive taste in conservative living. Lovers of fine music will appreciate the added advantage of Parquet for its outstanding acousticqualities. Incorporate inlaid feature strips or intricate border patterns to achieve that “air-of-distinction” in one’s interior design.

“Embossed Parquet”

Mosaic and Block

“Embossed Parquet” should be used in any area where a HI-TRACTION Work Floor is required around machinery. The product is typically being used by Schools and Colleges in the wood Work, Metal Work and Craft Areas of these buildings. The product is ideal for use in both office and workshop areas of small engineering works where people can walk their dirty, greasy boots all over the product, without care. The floor does provide very good thermal insulation in addition to being well suited for the use of electric tools. It is important to recognise that, “Embossed Parquet” is not designed as a floor of beauty, but as a practical work floor and for its safety attributes. With all that however, creative people have used the product to establish an environment that projects that rustic or old world charm, in restaurants, galleries and the like.

“Anchor-Loc” Hi-Point-Load, Structural Sheet Sub-Floor  

This System should be used only when existing sub-floors need up-grading to produce either a structurally sound or suitably “key-able” surface. The System is most often used to provide different facilities in existing structures. While the sub-floor itself can be used as a finished floor, this is not intended, and the life of the top veneer of plywood would be limited.

“Pre-Plank” Parquet - Pre-finished Plank Parquet

“Pre-Plank”Parquet - Pre-finished Parquet Floorsis primarily designed for Domestic Installation and/or Shopping Centre Fit outs for areas where one wishes to create that unusual and decorative feature floor in longer strips of timber, with very rapid installation times.

Sub-Floor Requirements  

--------------------------------------------------------------------------------

Types Of Sub-Floors

All Australian Parquetry Industries Flooring Products are suitable for installing on any level, clean and dry sub-floor.

Broadly described, these include:

Concrete Trowelable Underlays Strip Timber Flooring Plywood Particle Board Or Sheet Flooring Hardboard Underlays

All of which must comply with the minimum requirements of I.S.O. 9000 or Australian Standard 1262 - 1972.

Concrete Sub-Floors

Concrete sub-floors must essentially be level, clean and dry. Concrete slabs on ground, or fill, as well as slabs placed over swimming pools, showers of other wet areas must be efficiently and effectively sealed against the rising of moisture vapour by the installation of a continuous water-vapour proof membrane. Special precautions are also necessary to prevent moisture entering the slab from the sides or ends. Concrete sub-floors over which parquet is to be installed are to be very good in respect to plainness and levelness of surface tolerances.

Plainness of the Surface - shall be to a minimum tolerance of 3 mm maximum deviation anywhere under a 3 metre straight-edge placed on the surface of the sub-floor  in any position.

Smoothness of the Surface - of the concrete shall be to a maximum tolerance that when a straight-edge 150 mm long is placed upon the surface at any position, no part of the surface shall be more than 1 mm below the straight-edge.

Cleanness Of The Surface - any surface over which parquet flooring is to be installed must be clean and free from all dirt, dust or other loose or deletarios material that could impair the bond of parquet to the surface.

It is also essential that under no circumstancesshould any curing compound, agent, admixture, wax, oil, grease or other deleterious substance contaminate the surface of the sub-floor as the adhesive bond will be impaired by their presence.

It is also essential to ensure that should any grinding of the surface of the slab be necessary, then this must be carried out dry with a coarse stone to ensure that the pore structure of the concrete does not become clogged with a slurry of concrete dust.  Should sub-floors be encountered that have been treated with curing compounds, additives, admixtures, etc. or contaminated in some way including wet grinding or a highly polished surface, the concrete sub-floor should undergo a thorough program of acid etchingto product a good key-able surface. Instruction on the method of acid etching as sub-floor preparation should be carefully studied. (See section on “Acid Etching”).

Sub-Floor Requirements  

--------------------------------------------------------------------------------

Trowel-able Underlayments

When concrete sub-floor levelling is required, the preferred methods are as follows: 1. If levelling is required over 19mm thick, then a carefully prepared mix of sand, cement and Cemstick underlay should be trowel-led to achieve the corrected levels. Sub-floor adjustments of this nature must be applied only after careful priming of the floor has been undertaken.

  1. Note: As this form of underlay is P.V.A. base the normal requirements of membrane and moisture content measurement still apply.

*** Note: Parquet flooring should not be laid on any concrete, magnesite or underlaid sub-floor having a moisture content in excess of 6% as measured by a Protimeter Concrete Master.

Strip Timber Flooring

The age, specie and condition of the timber floor dictate the treatment necessary to prepare same as a suitable sub-floor over which to install parquet. Moisture Content - In general terms the wooden sub-floor must simply be of seasoned timber, (within the range of 8-13%) of ambient moisture content and climatically adjusted to the environs in which it is to live.

It shall be of sound, true, timber, tightly nailed to the joists with at least two nails at each joist crossing in every floorboard. It shall be plane and smooth in accordance with I.S.O. 9000 or Rules 7.2 and 7.3 of Australian Standards A.S. 1262 (1972) and all nails must be punched below the surface.

In those cases where the sub-floor is excessively damaged or worn to an extent that sanding does not bring all sections of the floor to a plane surface of where there are gaps between the floorboards exceeding 2 mm, or where it has been coated or impregnated with a substance that cannot be thoroughly removed by sanding, then those portions shall be cut out and replaced or the sub-floor shall be covered with an approved sheet underlay according to Australian Standards. Basic sanding of the sub-floor to make clean and level shall be carried out in accordance with A.S. CA39 “Sanding of Interior Wooden Floors”.

In certain circumstances a structural sheet underlay may be recommended prior to installing parquet. Of great importance in working over any timber sub-floor is good sub-floor ventilation to avoid still, damp air.

Timber

Timber sub-floors should be identified as being either new or old. If sub-floor is new, one needs to ascertain that the timber used has been correctly kiln dried and has not been wet with rain or by washing down brickwork etc., or been affected in some other obscure manner. All timber sub-floors intended to be sheeted with underlays should conform to the following:-

Sub-Floor Requirements

--------------------------------------------------------------------------------

Timber

Timber Underlays

i)          12 mm Structural Grade, Waterproof Exterior, 3 ply plywood underlay - Grade “A” Bond.

 ii)        6 mm tempered hardboard or cement based underlay.

All timber sub-floors must be level prior to sheeting with any one of the above underlayments and therefore should be coarse sanded, where necessary. Fixing of underlays must be strictly in accordance with I.S.O. 9000 or Australian Standards and where parquet is being laid over existing underlays, a careful inspection must be undertaken to ensure that the method of fixing and structural capacity of the existing underlay is satisfactory.

Structural Sheet Sub-Floors - Plywood/Particle Board/Asbestos Cement Sheeting.

The preferred form of Structural Sheet Flooring is plywood having a Type “A” Bond and complying with the requirements of A.S. 085.

Pinus Structural Plywood or Equivalent Hardwood Structural Plywood, may be used. The durability and thickness of the sheets shall be in accordance with A.S. CA38, S.A.A. Light Timber Framing Code.

Sheets shall be laid with their face piles at right angles to the line of supporting joists, and joints parallel to joists shall be staggered. Ends of sheets shall be butted centrally over joists, and edges of sheets, unless tongued and grooved, shall be joined centrally over noggings between joists, such noggings being of timber not less than 70 mm by 35 mm in section and set flush with the top of the joists. Nails used for fixing the sheets to the joists shall be not less in length than 2.5 times the thickness of the sheet and shall be spaced as follows:

a)         Flathead Nails - 150 mm centres along ends of sheets and 300 mm centres along edges.

b)         Jolt (Bullet) Head Nails - 100 mm centres along ends of sheets and 200mm centres along edges.

Sub-Floor Requirements

--------------------------------------------------------------------------------

Sub-Floor Preparation

Concrete/Timber/Plywood/Particle Board/Magnesite

The sub-floor surface over which any parquet floor is to be installed must be structurally sound, level, clean and dry and free from dust, dirt and loose material.

Underlayments

Underlayments generally take two forms:

a)         Trowel-led Underlayments can vary in type according to specific job needs. Generally, however, trowel-led underlays are used for either filling or levelling. It is recommended that advice be requested from our Technical Staff following a site inspection of specific projects.

As all underlayments are not the same, nor will they perform the same job.

Generally speaking, trowel-led underlays shall be placed, spread, screeded and/or steel trowel-led as recommended by the manufacturer of the nominated underlayment, all in accordance with Rules 5.2 and 5.3. Australian Standard 1262 (1972).

b)         Sheet Underlays - shall be laid and fixed over wooden sub-floors as follows:

i)          The underlay shall be laid “Brickbond”, with the sheets staggered in one direction. No gap between sheets shall be more than 3mm wide. The sheets shall be nailed at 100 mm centres on all edges and 15 mm away from the edges. The sheets shall be further nailed at intervals of 200 mm centre-to-centre in each direction.

ii)         The nails shall be 25 mm x 14 gauge ring-grooved buttress nails (underlay nails) or divergent point staples not less than 25 mm long.

iii)        Nails and staples shall be driven flush with or below the underlay surface.

iv)        Where necessary, the underlay should be lightly sanded at the joints to relieve discrepancies in height or unevenness from nails or staples so that it will comply with Rules 5.2 and 5.3 A.S. 1261 (1972).

v)         The underlay shall be laid to within 10 mm of all vertical surfaces to allow an expansion gap.

vi)        Should there be discrepancy of levels at the abutment of any sheets, these shall be made level by planing or sanding prior to proceeding with the laying of parquet.

Sub-Floor Requirements

Inspection and testing of Sub-Floors

--------------------------------------------------------------------------------

Concrete/Magnesite-Sub-Floors

Thrust Floors International Pty. Ltd. as the nominated Sub-Contractor, takes full responsibility for thoroughly inspecting and moisture testing every sub-floor over which it is to install parquetry prior to carrying out any installation.

The methods of inspection and testing shall be as follows:

1. Firstly, a visual inspection shall be made of the sub-floor to search for any obvious contaminates on the surface of the floor which may impair bonding of the parquet to the sub-floor. In this inspection, should it be considered that acid etching, dry grinding or the like be necessary or desirable to bring the sub-floor surface to a more suitable condition, then such recommendations shall be submitted in writing to the Supervising Officer.

2. During the course of inspecting sub-floors, a check procedure shall be undertaken with a straightedge to ensure that tolerances of plainness and levelness conform to specified requirements. It shall be the responsibility of the Head Contractor to rectify any section of the sub-floor which does not meet the required specifications and shall present the Specialist Flooring Contractor with levels and tolerances “as specified”.

3. Shear testing procedures shall only be carried out by Thrust Floors International Pty. Ltd. utilising a certified “B.W. Shear Testing Device”.

4. Where specified, a thorough program of moisture testing of concrete, magnesite and/or composition sub-floors shall be undertaken by Thrust Floors International Pty. Ltd.

A written record of all moisture tests shall be carefully maintained in chronological order and shall be available for inspection by the Supervising Officer upon request. Should slow drying impede completion of sections of the works, then specific inquiry should be made from our Technical Division regarding preferred recommendations on treatment for specific projects.

 

Moisture Testing - Timber and Timber Sub-Floors

Moisture content testing of timber shall be determined by the electrical moisture meter method as described in Australian Standards A.A. 1080 Section 3, Methods of Test for Timber (Part 1 - Moisture Content.) At the time of installation of parquet flooring the moisture content of the timber sub-floor shall be between 8 and 15 per cent.

Sub-Floor Requirements  

--------------------------------------------------------------------------------

Moisture Testing Equipment

Concrete and/ or Magnesite Sub-Floors

A concrete and/or magnesite sub-floor or any trowel-led underlay shall have a moisture content not exceeding 6 per cent. The moisture content shall be determined by use of either:

a)         C.M. Apparatus - for absolute measurement (is the preferred method). b)         Protimeter Concrete Master - probe testing with gauge readings.

Moisture testing shall be undertaken of every individual floor area over which parquet is to be laid or at a rate not less than one test per 100 m2 of floor area.

********************

Acid Etching  

Where required to remove surface contaminants the following procedure for acid etchingMUST be undertaken. Acid mix shall be a 3-1 mix of Hydrochloric (muriatic) Acid and water. Being 1 gallon of acid added to 3 gallons of water. Acid etching shall be undertaken in controlled spaces that are free from other trades. The acid mix shall be spread onto the floor by using plastic watering cans to give an even distribution of acid. The mix shall then be worked around the floor until foaming and effervescence has ceased in all areas and the acid has ‘gone dead’. The acid solution on the floor shall then be diluted by watering the area with clean, clear water immediately prior to removing the solution with a wet-pick-up vacuum cleaner.

Note: While the solution that is removed from the floor is regarded as ‘dead acid’ recommendation is made that approval be sought on the disposal of waste material from the client or client’s representatives prior to commencement of work. After initial removal of dead acid from the floor, it is necessary to repeat the process of acid etching on all areas where effervescence failed to take place effectively and/or where there may be other visible signs of areas requiring rework.

On completion of the etching procedure it is absolutely essential that a very thorough program of washing and scrubbing with clean, pure water be undertaken to remove all presence of acid salts. If this procedure is not carried out very efficiently, it would be better if acid etching had never been undertaken. In this, it is simply a matter of care and attention to ensure that plenty of effort is used in scrubbing the surface with clean water and a clean stiff bristle broom prior to picking up the water with wet-pick-up equipment. The procedure of washing and scrubbing is usually repeated up to six (6) and more times depending entirely on the condition of the sub-floor. The amount of etching and scrubbing required is ofen-AU color: #000000;ten something that must be determined during the currency of the work. Wherever possibl font-size: small;e, it is desirable to allow a minimum of 24 hours to elapse between the completion of acid etching and the commencement of laying parquetry in any area. Given certain conditions it is possible for laying to commence prior to that time, but rtext-align: justify;span style=/preecommendation is made that consultation be made with out Technical Department on the circumstances of each project. It is recommended that acid etching be regarded as essential in any specification where epoxy adhesives are to be used or wherever one is establishing a bond for Hi-Point-Loaduse.

Sub-Floor Requirements  

--------------------------------------------------------------------------------

Heated Sub-Floors

 

While it is possible to install parquet flooring over sub-floors heated by either electrical heating coils or hot water pipes, it is more desirable to avoid the use of sub-floor heating altogether. It is much more desirable to provide heating by some other method, wherever practically possible. This practical recommendation is made primarily because of the very detailed and precise nature of the parquet installation in such circumstances, and history has shown that the failure of sub-floor thermostats and the uncontrolled, adhoc manipulation of controls by unauthorised personnel has brought about situations where sub-floor heating has gone way beyond design limits, causing failure of concrete toppings as well as floor coverings, in all, necessitating extensive and costly rectification and great disruption to the normal use of the building. Now if we have not convinced you that sub-floor heating does represent potential danger, the following procedure must be carefully adopted in the execution of any parquet or hardwood flooring installation over heated sub-floors. 1. Firstly, ensure that the heating system itself contains the maximum practical number of safeguards possible to protect the system from failure. In this we advise at least one sub-floor thermostat per room or at least one every 50 square metres of floor area.

2. Heating coils of either type must have at least 50 mm of top cover through which the heat is dissipated to ensure that heating of the floor is uniform.

It is also essential in the installation of heating coils to ensure that the coils themselves are laid onto an even surface so that the concrete topping applied over the heating system is common in thickness. Failure to observe strict adherence to this procedure can easily result in “hot spots” in the floor causing greater heat leakage in spots where coils might be immediately below the parquet instead of having 50 mm top cover. These hot spots in turn will result in excess loss of moisture of the timber installed in these areas, that loss of moisture being evident in the form of a small joint becoming evident around individual blocks of timber in the floor. It is also true that at various times of the year even a well installed parquet floor over a heated sub-floor will experience sufficient loss of moisture to produce a tiny hairline joint around every finger or block of timber. However, when conditions return to normal and a small amount of humidity comes back into the air, the floor then returns to its previous state. The maximum temperature that any sub-floor should reach for parquet to be a successful installation is 26 deg. C (89 deg. F)

Sub-Floor Requirements  

--------------------------------------------------------------------------------

Heated Sub-Floors

Procedure for installing Parquet over Heated Sub-Floors

a)      A minimum of sixteen days prior to the installation of parquet sub-floor heating system is to be turned on to the maximum normal operating range at which the system is designed to operate and should be kept in full and constant operation 24 hours a day for a minimum of 14 days prior to installation of the parquet. Full heat should be realised through gradual increase over a period of 24 hours.

b)      48 hours prior to installation, the heating system is to be turned completely off (unless in places such as very cold climates where our Senior Technical Staff may recommend ‘just a little warmth’ be given the slab to remove that dead cold situation). The slab is then left to cool for that 48 hour period during which time any condensation that may have taken place during cooling will have dissipated. The flooring installation is effected.

c)      The heating system then remains completely off for a minimum of 7 days after the installation has been completed. Seven days after the installation has been completed, the heating system may be turned on very gradually taking seven (7) days before the system reaches its normal operating high. The system is then to be kept running 24 hours per day for a minimum period of fourteen (14) days before the programming of sanding and finishing is undertaken.

d)     A minimum of 48 hours must elapse after the heating system has been turned off prior to commencing the program of sanding and finishing.

e)      In specifying finishing materials for heated sub-floors it is essential to remember that polyurethane finishes are totally unsuitable for use in these situations, and in lieu the floor is treated with a special preparation for wood oils which are ‘wet burnished’ deep into the fibres of the timber to preserve the wood. This process then complements, very well, the normal maintenanceschedulefor parquet over heated sub-floor installations, which includes feeding the floor with an occasional coat of good quality spirit-based wax polish, to give the floor that regular food and nourishment that it requires.

Our closing comments on the use of any sub-floor heating system are:

Ensure that any wall-mounted or other manual control units are totally enclosed or positioned so that only experienced and competent people have access to the controls which should not be adjusted up and down from nothing to “full blast” a dozen times each day. The practice of installing a dummy set of controls to satisfy the whim of interfering patrons is one of which we approve. Experience has shown that misuse of these controls will prove too much for any floor covering to cope with and eventually leads to floor failure.

In those cases where the sub-floor is excessively damaged or worn to an extent that sanding does not bring all sections of the floor to a plane surface of where there are gaps between the floorboards exceeding 2 mm, or where it has been coated or impregnated with a substance that cannot be thoroughly removed by sanding, then those portions shall be cut out and replaced or the sub-floor shall be covered with an approved sheet underlay according to Australian Standards. Basic sanding of the sub-floor to make clean and level shall be carried out in accordance with A.S. CA39 “Sanding of Interior Wooden Floors”. In certain circumstances a structural sheet underlay may be recommended prior to installing parquet. Of great importance in working over any timber sub-floor is good sub-floor ventilation to avoid still, damp air.

Timber

Timber sub-floors should be identified as being either new or old. If sub-floor is new, one needs to ascertain that the timber used has been correctly kiln dried and has not been wet with rain or by washing down brickwork etc., or been affected in some other obscure manner. All timber sub-floors intended to be sheeted with underlays should conform to the following:-

Sub-Floor Requirements  

--------------------------------------------------------------------------------

Timber

Timber Underlays

i)          9 mm Structural Grade, Waterproof Exterior, 3 ply plywood underlay -      Grade “A” Bond.

ii)         6 mm tempered hardboard or cement based underlay.

All timber sub-floors must be level prior to sheeting with any one of the above underlayments and therefore should be coarse sanded, where necessary. Fixing of underlays must be strictly in accordance with I.S.O. 9000 or Australian Standards and where parquet is being laid on existing underlays, a careful inspection must be undertaken to ensure that the method of fixing and structural capacity of the existing underlay is satisfactory.

Structural Sheet Sub-Floors - Plywood/Particle Board/Asbestos Cement Sheeting.

The preferred form of Structural Sheet Flooring is plywood having a Type “A” Bond and complying with the requirements of A.S. 085, Pinus Structural Plywood or Equivalent Hardwood Structural Plywood, may be used. The durability and thickness of the sheets shall be in accordance with A.S. CA38, S.A.A. Light Timber Framing Code. Sheets shall be laid with their face piles at right angles to the line of supporting joists, and joints parallel to joists shall be staggered. Ends of sheets shall be butted centrally over joists, and edges of sheets, unless tongued and grooved, shall be joined centrally over noggings between joists, such noggings being of timber not less than 70 mm by 35 mm in section and set flush with the top of the joists. Nails used for fixing the sheets to the joists shall be not less in length than 2.5 times the thickness of the sheet and shall be spaced as follows:

a)         Flathead Nails - 150 mm centres along ends of sheets and 300 mm centres along edges.

b)         Jolt (Bullet) Head Nails - 100 mm centres along ends of sheets and 200mm centres along edges.

MAGNESITE

Magnesite sub-floors must be of a high quality and should only be tested by using a C.M. Apparatus. Magnesite sub-floors should have a skim coat of Ardit Z8 trowelled onto the surface and allowed to dry prior to laying parquet. Alternatively, if surface is close and tight, a prime coat of “Hi-Bond” Adhesive may be used as a primer to limit excessive absorption.

Sub-Floor Requirements  

--------------------------------------------------------------------------------

Sub-Floor Preparation

Concrete/Timber/Plywood/Particle Board/Magnesite

The sub-floor surface over which any parquet floor is to be installed must be sound, level, clean and dry and free from dust, dirt and loose material.

Underlayments

Underlayments generally take two forms:

a)         Trowel-ledUnderlayments can vary in type according to specific job needs.

Generally, however, trowel-led underlays are used for either filling or levelling. It is recommended that advice be requested from our Technical Staff following a site inspection of specific projects. As all underlayments are not the same, nor will they perform the same job. Generally speaking, trowel-led underlays shall be placed, spread, screeded and/or steel trowel-led as recommended by the manufacturer of the nominated underlayment, all in accordance with Rules 5.2 and 5.3. Australian Standard 1262 (1972).

b)         Sheet Underlays - shall be laid and fixed over wooden sub-floors as follows:

i)          The underlay shall be laid “Brickbond”, with the sheets staggered in one direction. No gap between sheets shall be more than 3mm wide. The sheets shall be nailed at 100 mm centres on all edges and 15 mm away from the edges. The sheets shall be further nailed at intervals of 200 mm centre-to-centre in each direction.

ii)         The nails shall be 25 mm x 14 gauge ring-grooved buttress nails (underlay nails) or divergent point staples not less than 25 mm long.

iii)        Nails and staples shall be driven flush with or below the underlay surface.

iv)        Where necessary, the underlay should be lightly sanded at the joints to relieve discrepancies in height or unevenness from nails or staples so that it will comply with Rules 5.2 and 5.3 A.S. 1261 (1972).

v)         The underlay shall be laid to within 10 mm of all vertical surfaces to allow an expansion gap.

vi)        Should there be discrepancy of levels at the abutment of any sheets, these shall be made level by planing or sanding prior to proceeding with the laying of parquet.

Inspection And Testing Of Sub-Floors

Concrete/Magnesite-Sub-Floors

Thrust Floors International Pty. Ltd. as nominated Sub-Contractor, takes full responsibility for thoroughly inspecting and moisture testing every sub-floor over which it is to install parquetry prior to carrying out any installation. The methods of inspection and testing shall be as follows: 1. Firstly, a visual inspection shall be made of the sub-floor to search for any obvious contaminates on the surface of the floor which may impair bonding of the parquet to the sub-floor. In this inspection, should it be considered that acid etching, dry grinding or the like be necessary or desirable to bring the sub-floor surface to a more suitable condition, then such recommendations shall be submitted in writing to the Supervising Officer.

  1. During the course of inspecting sub-floors, a check procedure shall be undertaken with a straightedge to ensure that tolerances of plainness and levelness conform to specified requirements. It shall be the responsibility of the Head Contractor to rectify any section of the sub-floor which does not meet the required specifications and shall present the Specialist Flooring Contractor with levels and tolerances “as specified”.

1. Shear testing procedures shall only be carried out by Thrust Floors International Pty. Ltd. utilising a certified “B.W. Shear Testing Device”.

2. Where specified, a thorough program of moisture testing of concrete, magnesite and/or composition sub-floors shall be undertaken by Thrust Floors International Pty. Ltd. A written record of all moisture tests shall be carefully maintained in chronological order and shall be available for inspection by the Supervising Officer upon request. Should slow drying impede completion of sections of the works, then specific inquiry should be made from our Technical Division regarding preferred recommendations on treatment for specific projects.

Moisture Testing - Timber and Timber Sub-Floors  

Moisture content testing of timber shall be determined by the electrical moisture meter method as described in Australian Standards A.A. 1080 Section 3, Methods of Test for Timber (Part 1 - Moisture Content.) At the time of installation of parquet flooring the moisture content of the timber sub-floor shall be between 8 and 15 per cent.

Sub-Floor Requirements

--------------------------------------------------------------------------------

Moisture Testing Equipment

Concrete and/ or Magnesite Sub-Floors A concrete and/or magnesite sub-floor or any trowel-led underlay shall have a moisture content not exceeding 6 per cent. The moisture content shall be determined by use of either:

a)         C.M. Apparatus - for absolute measurement (is the preferred method).

b)         Protimeter Concrete Master - probe testing with gauge readings. Moisture testing shall be undertaken of every individual floor area over which parquet is to be laid or at a rate not less than one test per 100 m2 of floor area.

********************

Acid Etching  

Where required to remove surface contaminants the following procedure for acid etching MUST be undertaken. Acid mix shall be a 3-1 mix of Hydrochloric (muriatic) Acid and water. Being 1 gallon of acid added to 3 gallons of water. Acid etching shall be undertaken in controlled spaces that are free from other trades. The acid mix shall be spread onto the floor by using plastic watering cans to give an even distribution of acid. The mix shall then be worked around the floor until foaming and effervescence has ceased in all areas and the acid has ‘gone dead’. The acid solution on the floor shall then be diluted by watering the area with clean, clear water immediately prior to removing the solution with a wet-pick-up vacuum cleaner.

Note: While the solution that is removed from the floor is regarded as ‘dead acid’ recommendation is made that approval be sought on the disposal of waste material from the client or client’s representatives prior to commencement of work. After initial removal of dead acid from the floor, it is necessary to repeat the process of acid etching on all areas where effervescence failed to take place effectively and/or where there may be other visible signs of areas requiring rework. On completion of the etching procedure it is absolutely essential that a very thorough program of washing and scrubbing with clean, pure water be undertaken to remove all presence of acid salts. If this procedure is not carried out very efficiently, it would be better if acid etching had never been undertaken. In this, it is simply a matter of care and attention to ensure that plenty of effort is used in scrubbing the surface with clean water and a clean stiff bristle broom prior to picking up the water with wet-pick-up equipment. The procedure of washing and scrubbing is usually repeated up to six (6) and more times depending entirely on the condition of the sub-floor. The amount of etching and scrubbing required is often something that must be determined during the currency of the work. Wherever possible, it is desirable to allow a minimum of 24 hours to elapse between the completion of acid etching and the commencement of laying parquetry in any area. Given certain conditions it is possible for laying to commence prior to that time, but recommendation is made that consultation be made with out Technical Department on the circumstances of each project. It is recommended that acid etching be regarded as essential in any specification where epoxy adhesives are to be used or wherever one is establishing a bond for Hi-Point-Load use.

Sub-Floor Requirements  

--------------------------------------------------------------------------------

Heated Sub-Floors

While it is pos/spanfont-size: small;/precolor: #000000;sible to install parquet flooring over sub-floors heated by either electrical heating coils or hot water pipes, it is more desirable to avoid the use of sub-floor heating altogether. It is much more desirable to provide heating by some other method, wherever practically possible. This practical recommendation is made primarily because of the very detailed and precise nature of the parquet installation in such circumstances, and history has shown that the failure of sub-floor thermostats and the uncontrolled, adhoc manipulation of controls by unauthorised personnel has brought about situations where sub-floor heating has gone way beyond design limits, causing failure of concrete toppings as well as floor coverings, in all, necessitating extensive and costly rectification and great disruption to the normal use of the building. Now if we have not convinced you that sub-floor heating does represent potential danger, the following procedure must be carefully adopted in the execution of any parquet or hardwood flooring installation over heated sub-floors. 1. Firstly, ensure that the heating system itself contains the maximum practical number of safeguards possible to protect the system from failure. In this we advise at least one sub-floor thermostat per room or at least one every 50 square metres of floor area.

  1. Heating coils of either type must have at least 50 mm of top cover through which the heat is dissipated to ensure that heating of the floor is uniform.

It is also essential in the installation of heating coils to ensure that the coils themselves are laid onto an even surface so that the concrete topping applied over the heating system is common in thickness. Failure to observe strict adherence to this procedure can easily result in “hot spots” in the floor causing greater heat leakage in spots where coils might be immediately below the parquet instead of having 50 mm top cover. These hot spots in turn will result in excess loss of moisture of the timber installed in these areas, that loss of moisture being evident in the form of a small joint becoming evident around individual blocks of timber in the floor. It is also true that at various times of the year even a well installed parquet floor over a heated sub-floor will experience sufficient loss of moisture to produce a tiny hairline joint around every finger or block of timber. However, when conditions return to normal and a small amount of humidity comes back into the air, the floor then returns to its previous state. The maximum temperature that any sub-floor should reach for parquet to be a successful installation is 26 deg. C (89 deg. F)

Sub-Floor Requirements  

Heated Sub-FloorsProcedure For Installing Parquet Over Heated Sub-Floors

a)      A minimum of sixteen days prior to the installation of parquet sub-floor heating system is to be turned on to the maximum normal operating range at which the system is designed to operate and should be kept in full and constant operation 24 hours a day for a minimum of 14 days prior to installation of the parquet. Full heat should be realised through gradual increase over a period of 24 hours.

 

b)      48 hours prior to installation, the heating system is to be turned completely off (unless in places such as very cold climates where our Senior Technical Staff may recommend ‘just a little warmth’ be given the slab to remove that dead cold situation). The slab is then left to cool for that 48 hour period during which time any condensation that may have taken place during cooling will have dissipated.

 

c)      The flooring installation is effected.

 

d)     The heating system then remains completely off for a minimum of 7 days after the installation has been completed.

e)      Seven days after the installation has been completed, the heating system may be turned on very gradually taking seven (7) days before the system reaches its normal operating high. The system is then to be kept running 24 hours per day for a minimum period of fourteen (14) days before the programming of sanding and finishing is undertaken.

 

f)       A minimum of 48 hours must elapse after the heating system has been turned off prior to commencing the program of sanding and finishing.

 

g)      In specifying finishing materials for heated sub-floors it is essential to remember that polyurethane finishes are totally unsuitable for use in these situations, and in lieu the floor is treated with a special preparation for wood oils which are ‘wet burnished’ deep into the fibres of the timber to preserve the wood.

This process then complements, very well, the normal maintenanceschedule for parquet over heated sub-floor installations, which includes feeding the floor with an occasional coat of good quality spirit-based wax polish, to give the floor that regular food and nourishment that it requires.

Our closing comments on the use of any sub-floor heating system are:

Ensure that any wall-mounted or other manual control units are totally enclosed or positioned so that only experienced and competent people have access to the controls which should not be adjusted up and down from nothing to “full blast” a dozen times each day. The practice of installing a dummy set of controls to satisfy the whim of interfering patrons is one of which we approve. Experience has shown that misuse of these controls will prove too much for any floor covering to cope with and eventually leads to floor failure.

Where You Should Use Parquet- And Why  

--------------------------------------------------------------------------------

Domestically

Parquet in its many forms can be used in almost any area of the average home, with the exception of external, bathroom and laundry areas which are traditionally “wet” areas. Parquet can be utilised to transform any home into a carefree place to live. As parquet is a natural product, aesthetically it compliments many other aspects of your home and decor. Being one of the world’s best insulators (hence the extensive use of timber in the coldest climates in the world) parquet is a comfortably warm product underfoot. In living areas of your home, parquet will give you decades of use and still retain that handsome character that only nature can impart.

Decorating with parquet is so simple and is extremely versatile. By simply moving a hide or scatter rug from one room to the next you can change your entire decor.

Economically you can’t afford not to have a parquet floor. For around the same cost as any other quality floor covering, you can have a hand crafted piece of nature, right in your home. With normal care those floors will probably outlive you. What other floor covering can you install that can be completely rejuvenated to a “brand new condition” after years of service. Remember, today the only thing that counts is the value of your assets. Parquet will add substantially to the value of any home, old or new and in resale value the wisdom is realised in that your parquet floor coverings are adding daily to the value of your home.

Can you really imagine just how much it is going to cost to re-carpet or re-floor a home 10 years from now - when it’s already costing so much today!

The ability, on resale of your home, to be able to present your prospective client with “as brand new” floor coverings (the hardest wear item in any home) is an asset that is as good as money in the bank.

Significant health advantages

Asthma and hay fever sufferers find parquet a boon, for with the use of an Electrostatic Dust Control Mop, you can ensure that your house is spotlessly free of dust and animal hair with just a simple 2 minute job. Parquet is just so simple to maintain and keep clean and very resistant to stains and soil.

In the kitchen, you can retain the beauty of natural timber to compliment your cupboards and bench work. Our showrooms have ample displays of luxurious parquet, suitable for bench tops, that will so impress you. You will be surprised how harmonious an environment you can create when you break free of that world of plastics in which we have become so entangled. Our showrooms present you with the choice of over one hundred patterns and designs with large areas displayed.

Where You Should Use Parquet - And Why  

--------------------------------------------------------------------------------

Commercially

Commercially, parquet has almost limitless uses.

Economically it is worthwhile studying two extensive research publications on floors and floor maintenancecosts. These two studies conducted firstly by the Swiss Institute of Domestic Science and secondly by David G. Martens, Bachelor of Science in Forest Products, Iowa State University, USA and Master’s Degree in Wood Technology, are available from the Company’s various technical libraries. The extensive research undertaken by both studies, which covers a broad spectrum of floor coverings used domestically, in office building, public halls and buildings, restaurants etc., clearly shows that parquet and hardwood flooring systems are dollar for dollar considerably more economical and can certainly demonstrate “cost effectiveness” in every sense of the word. Parquet is ideal for use in any of the following commercial situations:

* Schools * Motor Car Showrooms * Multi-Purpose Halls * Feature Floors - Ceilings - Walls * Clubs * Recording Studios * Banks * Colleges * Restaurants * Universities * Dance Floors * Printing Factories * Offices * Churches * Kindergartens and Pre-Schools * Wine Bars * Industrial Work Areas * Public Areas (Internal) * Theatres * Entrance Foyers * Home Units * Libraries * Projects where the absence of dust and the absence of dirt in a work area                                                                     represents avoidance of machine breakdowns * Projects where static electricity originating from floor coverings is essential * Projects requiring electrical insulation and/ or thermal insulation

If you appreciate fine music, you cannot be without the perfect touch of parquet with all its tremendous acoustic advantages. As the years go by, one can easily add onto an existing parquet floor, repair or replace a section if needs be, without being able to discern a difference. Here one is not bound by the restrictions of changing fashion colours.

Where You Should Use Parquet - And Why

Industrially

 

Parquet performs an impressive role. Many heavy industrial situations are extremely demanding of any flooring system. Many people in the work place don’t always use machines and equipment with the care that they should. Therefore, there is tremendous advantage in having a flooring system that can cope with almost any situation, does not require costly maintenance, and can be completely rejuvenated many, many times in its life should that be desirable. In projects such as printing works where the highly abrasive dirt and grit off concrete and similar floors can stop production and cost a fortune in maintenance, hi-performance parquet floors, especially where used End Grain, can give decades of use without showing any appreciable wear. In hot metal works where hot castings, etc. can’t be stored on cold concrete floors, heavy wood blocks take heaps of abuse and provide excellent protection for the products being manufactured. Because parquet and hardwood flooring is manufactured from pure lumber and is a totally natural product, it lives and breathes throughout its life. In this process of breathing the cellular construction of the wood fibre absorbs and gives off moisture. If placed in external situations, or in locations that can generally be described as “wet areas”, timber in a flooring situation can uptake excessive amounts of moisture which can cause buckling. Alternatively, if timber is placed in situations that from time to time experience severe heat or extreme dry conditions, then shrinkage can take place. In short, one simply needs to apply common sense in the use and application of the product and the proudest of results shall be forthcoming.

Therefore:

 

Do not use in external or exposed situations Do not use in “wet areas” Do not use in severe heat or extreme dry locations without consultation with our Technical Department for specific advice on the industrial applications.

W/spanbr /span style=hen used in air conditioned buildings, it is desirable to have thespan style=text-align: justify; text-indent: -0.64cm; margin-bottom: 0cm; margin-left: 1.27cm;/spanspan lang= air conditioning in full, effective and constant balanced operation prior to the flooring installation. Where possible double the period between laying and sanding and finifont-size: small;shing, for best possible results. If used over heated sub-floors, a particular sequence of laying and finishing must be established along with a schedule of heating times, to achieve the optimum result. The prime objective should be to install any product or material under similar conditions to which it will continually live, if perfection is to be achieved.

Floor Finishes

--------------------------------------------------------------------------------

 

 

Types, Details and Comments

Floor finishes, surface treatments and coatings are really a subject all of their own. However, this section of our Technical Catalogue confines itself broadly to the types and styles of floor finishes without discussing specific brands. In short, there are two types of surface coatings, being in the form of penetrating oils or surface sealers, alternatively, surface coatings such as polyurethane or epoxies. In general, our organization strongly supports use of the penetrating oils and sealers for the majority of commercial installations. These penetrating systems being applied until the surface is finally brought to a thoroughly sealed state. In this way one ends up with a thin surface of finish on the face of the product which is usually maintained with an occasional application of a first quality spirit based wax polish, while beneath is a good depth of wood fibre thoroughly saturated with deep penetrating timber seal. Polyurethane or plastic finishes and/ or epoxy finishes also have their place. In the home many people prefer a polyurethane finish. On kitchen floors and the like it is simply a matter of client choice, for with normal care and attention, either are equally suitable. However, with time at a premium most people opt for the easy care that polyurethane offers, without the need to polish. Dependent on the specific use to which each floor is put, our general recommendations are as follows. However, we would encourage you to consult our Technical Division for their specific advice on the known use of particular projects. 1. Domestic and straight forward Commercial Installations

Three (3) full coats Hi-Solid Polyurethane Coating. 1. Heavier Commercial and Industrial Applications

Two (2) full coats of Tung Oil Sealer (which on many projects is conducted using the American “wet burnished” technique to drive the fine wood oils deep into the pores of the wood). Finishing is again with Slip Retardant Spirit Based Wax Polish, buffed to a soft satin sheen. 1. Stadium and Gymnasium Floors

Stadium and Gymnasium Floors require very special finishing. One must firstly understand whether the facility is to be used strictly for Sports Hall Activity or whether as a Multi-Purpose Activities Area. Here, one must understand that there is no such finish as the “optimum” for all activities. The best finish for Ballroom Dancing will not be the best finish for Basketball and vice versa.

Floor Finishes

--------------------------------------------------------------------------------

Types, Details and Comments

Multi-Purpose Gymnasium use, one has the choice between:

a).        Two full coats of satin finish timber sealer which is able to be treated with a “traffic-able surface” of acrylic coating. The acrylic surface in this situation is able to be kept in excellent condition with very little effort. The procedure involved here requires only the use of the scissor type electrostatic dust control mop which keeps all dirt, grit and dust from abrading the surface of the floor. Any marks, for instance, white sand-shoe marks where a player may stop violently, twist, turn and take-off again, are very simple removed by occasionally going over the floor with a vacuum pick-up polishing machine using only a clean, dry bristle brush or very fine nylon burnishing pads.

b).        This method again for Multi-Purpose Gymnasium use involves the application of: Two (2) full coats of Deep Penetrating Timber Sealer and one (1) full coat of Super Sports Hall Surface Finish. (Alternatively, in given situations it can be more acceptable to apply one (1) coat of Deep Penetrating Timber Sealer and two (2) full coats of Super Sports Hall Finish). Either of these floor treatments are highly suitable for maintenancewith the Acrylic floor treatment described on the previous page.

Sports Stadiums - Indoor Sporting Use

Here one can make practical use of the Polyurethane Finish. As with epoxies, there are polyurethane and polyurethane, and they do not all perform anything like the same. Generally speaking, polyurethane will give you excellent traction but introduce much higher reflective qualities into your floor finish making it essential that the correct stadium lighting is installed to compliment the floor finish. Being a surface treatment, polyurethane and/or epoxy coatings set up on the surface of the timber and are therefore in a situation that scratching of the surface will leave a white mark. Polyurethane and / or epoxy coating are at the top end of the price range and are best utilised in stadiums used strictly for indoor sporting activities. There are a number of extremely fine products available on the world market and there is a wide difference in some of the pricing. Consultation with our Technical Department is encouraged prior to final documentation of floor finishes on major projects.

Maintenance

--------------------------------------------------------------------------------

 

The Do’sand Do Not’s

 

The maintenanceof our full range of products can broadly be covered by detailing maintenance of the following floor finishes. Generally speaking, however, the maintenance of any parquet or hardwood flooring system is very simple and quite economical. The prime requisite with any floor is to keep dirt, dust or grit to a minimum. By using a fine hair broom and/ or an electrostatic dust control mop, your floors can be kept in a very clean condition. Hardwood flooring finished with any of the following surface coatings should be maintained only with a first quality spirit based wax polish. These waxes are available with varying degrees of slip retardants which make them highly adaptable for use in almost any situation.

a) Satin finish timber seal b) Tung Oil seal c) Deep Penetrating Timber Seal

The greatest advantage in using surface coatings which are maintained in this way is that over the life of the floor, the oils and natural goodness from the spirit based wax continues to feed the wood fibre of the timber. Regular maintenance in this way can produce floors that look more and more handsome as the years go by, than the day that they were first installed. Just like a fine piece of furniture, that little bit of loving care can produce beautiful results on your floors. Any marks that might occur in this type of finish can simply be removed by using a cloth “dampened” with mineral turpentine. Really stubborn marks might sometimes require working with a thin application of wax broken down with mineral turpentine beneath a fine nylon pad under a polishing machine, but the finished result of the floor is always very handsome. Acrylic finishes, as applied to sports hall and multi-purpose facilities simply requires regular dusting with an electrostatic dust control mop to keep the surface free of abrasive dirt and grit. Other than this the occasional buffing of the floor with either a clean, dry bristly brush or fine nylon pad beneath a polishing machine, will keep the surface clean with a pleasant, low reflective surface. When, and as required, additional coats of acrylic can be applied by normal maintenance staff who do not require specialised training. The types of acrylic recommended by the company are self-levelling and very easy to apply without leaving lap marks or other faults in the coating. Polyurethane and/ or epoxy finishes generally require only regular mopping with electrostatic dust control mops to keep the surface free from abrasive dirt and grit. While the life of these coatings is usually very good, it is not uncommon that after a period of a few years, when they have become a little scratched and marked, that the floor may require being cut back and recoated with additional coats of the same materials. Here it should be understood that this is possible only where the surface of the floor has not been contaminated by the use of waxes, detergents, etc. which can affect the bonding of additional coats if not fully cut back.

Maintenance

--------------------------------------------------------------------------------

The Do’sand Do Not’s

The Do’s

Do keep your floors free of dirt, grit and abrasive particles.

Do use Electrostatic Mats and Mops to advantage wherever possible to cut down greatly the need for maintenance.

Do keep your sealed floors maintained with a first quality “spirit based” wax polish. (During the first two to three months of a new sealed flooring installation, you are advised to apply a thin even coat of wax to your floor on a weekly basis to feed and nourish the timber and to work your floors up to that cared for, handsome appearance).

Do feel free to use fine nylon pads beneath your polishing machine for both polishing and burnishing your sealed and wax finished floors.

Do take advantage of using vacuum pick-up polishing equipment in all commercial situations.

Do only use mineral turpentine to wipe over your floors or remove any marks. Use “sparingly”. Also use to remove any build up that might occur, which should never be necessary if a floor is maintained correctly.

The Do Not’s

Do not under any circumstances wash any timber or parquet floor with either hot or cold water. Do not use detergents of any kind on any wooden floor. Do not use water-emulsified wax polishes. Do not use any maintenanceproduct or procedure of which you are uncertain, without consulting our Technical Division. There are thousands of products on the Australian market which people advertise as being suitable for a particular use. Experience has proven that many of these people have little if any practical experience in the field and sometimes allow their advice to be guided by their order book. There could be no better advice given to any client than to “only” use products from reputable, well-known manufacturers, and even then, only after inquiring after our professional advice for your specific needs.

“Embossed Parquet”

 

Maintenanceof Australian Parquet Industries “Embossed Parquet” is almost negligible.

One of the most important primary advantages of the product is that it requires little more than broom sweeping to keep this floor looking very handsome. It should be clearly understood that the embossed textured finish on “Embossed” is primarily to provide a high traction industrial work surface and not to produce a floor of beauty.

However, the rugged appearance of the system has achieved wide acclaim from people in all walks of life for use in workshops, restaurants and many other buildings where that “old world” character is desired. Apart from broom sweeping to remove sawdust, shavings, filings or whatever from the surface, “Embossed Parquet” only requires mopping over with a solution comprising 50% linseed oil, 50% mineral turpentine and one pint of terebene to a gallon of that mixture.

This solution is best mopped on with a lambs wool applicator, being rubbed well into the surface of the timber. Applications of this mixture should be carried out approximately once every three (3) months and given overnight of preferably weekend or school holidays to dry, prior to use. It should be understood that the pure linseed oil feeds, nourishes and preserves the natural hardwood and requires no other maintenancein the form of washing, wax polishing, burnishing or buffing.

Under no circumstances should this flooring system be washed with water or spirit as it is quite unnecessary unless very unusual circumstances prevail (in which case consultation with our technical staff is recommended).

The Company would welcome any inquiry regarding the installation and/ or maintenanceof “Embossed Parquet” no matter how small your job may be.

“Air-Thrust” Pneumatic Squash Court Floors

Your “Air-Thrust” Pneumatic Squash Court Floor System which comprises parallel finger “white” specie parquet is considered by many to be the finest Squash Court Flooring System in the world.

To keep your floors in perfect condition all the time requires very little effort.

Firstly, we would strongly advise that the policy of allowing only white-soled sand-shoes to be used on the courts will help keep your Centre looking clean and bright. Your floors have been treated with a “special preparation” of fine wood oils which penetrates deep into the pores of the timber to nourish and preserve the wood fibre while maintaining a “high traction” surface on the court.

Should it from time to time be necessary to remove marks from the floor, this should be done by using a clean cloth only - “dampened” with mineral turpentine to rub over the surface. Should some section become badly marked, the surface may be lightly rubbed with a Beartex Pad, or “super-fine” steel wool lubricated with a small amount of mineral turpentine to rub over the surface. Care should be taken to ensure that the floor is not flooded with turpentine for one should use only the amount required to do the job.

Under no circumstances should water, detergent or other such materials be applied to the floor surface, it is recommended that the occasional use of a vacuum cleaner, especially around the perimeter and in the corners of the court, will remove the dust that regularly settles back into the court each night.
