SUPABOARD Lining Installation Guide
The below information and details are provided merely as a guide for intended applications.
Product Range and Details Thickness: 4.5mm, 6mm and 10mm are standard [3mm up to 25mm available on request] Dimensions: 900mm (W) x 1200mm (W); 2400mm (L); 2700mm & 3000mm as standard. Supaboard can be ordered to specific sizes on request (max. length 3000mm).
is a very easy product to handle despite its rigid nature. It must be installed in a "Tradesman-Like" manner and to best industry and trade practices, to get the desired durability and perfect finish. SUPABOARD's unique strength and controlled manufacturing process ensures it will exceed similar products in terms of durability and strength, improving its future performance.
SUPABOARD may be fixed to either light or heavy gauge domestic type steel frames, timber frames or timber battens over masonry. The framing and substrate used must comply with relevant building regulations and standards. It is also important to ensure that the frame is square and straight to provide the flush face to receive the sheeting.
Steel studs must be a minimum of 45 mm wide at joint face, and 0.55mm gauge minimum BMT (Base metal thickness). Steel framing must comply with the requirements of Australian Standards.
Timber framing must comply with the requirements AS 1684 and 'Timber Framed Buildings" and any other relevant standards. Studs must be provided at 600mm centres maximum, and noggins at 1200 mm centres nominal. Furthermore, timber studs must be a minimum 45mm wide.
SUPABOARD can be cut very easily with a carbide tip knife or any timber cutting tools, however if cutting a lot of material we recommend diamond cutting tools. For rough cuts, place the SUPABOARD smooth side up, scour along a straight line with the knife then snap along the scoured line. When cutting with power saws it is important that the blade teeth come through the smooth face, have the board smooth face down when cutting with power saws, or smooth face up with a hand saw. Finer cuts are achieved by using power tools such as a circular saw, jig saw, bench top saw etc. Service holes may be created by using drills, hole saws or jig saws.
NB: Please observe Occupation Health and Safety Practises as dust will result from mechanical cutting.
It is essential that back blocking is used in all flushed jointed applications see Diagram 1 and 2, SUPABOARD should not be joined on a stud as this is where most movement is in a frame. We recommend in wall linings that they are joined in-between metal or timber studs and back blocking the joints as shown in diagram 1, this can be done with fillets of SUPABOARD of the same thickness, they are then glued and fixed together with Supabond adhesive. Ends of sheets need to be back blocked and also fixed to steel furring channel or timber battens to keep sheet face straight when of a stud see diagram 4, 5 and 6.
For straight joints, align the recessed ends together, making sure that the joints are dry, clean and free from grease, oils or any other materials.
SUPABOARD in some cases may need to be primed before jointing and patching including in the joint itself, this will ensure that there will be a maximum adhesion of fillers and jointing compounds to the board in the jointing system used.
Please refer to attached the DuSpec for jointing and finishing, this can be downloaded from our downloads page on our website www.supaboard.com.au. We recommend that only fiberglass mesh is used in joints for external and internal application.
Embed the appropriate jointing tape (fiberglass mesh jointing tape) in a fine layer of jointing compound Dulux Acrapatch Coarse. Add another layer of jointing compound to the desired finish, wiping off any excess materials. This process will usually require a second coat being carful to keep the surface as flat as possible, any high spots will be difficult to sand back. Once this compound is set this can be top coated with AcraPatch fine in the same manner. The performance of every wall joint is the responsibility of its installer, as this is governed by the standard of workmanship and good industry trade practices.
There are several factors that may affect the joint performance, such as framing quality, movement and vibrations, moisture, weather exposure, humidity, temperature etc. These factors must be carefully understood and considered by the installer when selecting jointing compounds, by ensuring that the product selected has the physical attributes required to perform these considering factors, in some situation jointing may not be appropriate and a negative detail joint should be used. For corner joints, use a suitable corner reinforcement product and finish off with appropriate jointing compounds. If working conditions are hot and dry, dampen the area around the joint, prior to application.
BuilditEco cannot warrant other trades workmanship, we have put together this installation as a guilde to get the best result possible, however we cannot control every condition or situation when intalling these systems.
Ceiling linings must also be back blocked in the same way, however ceiling lining must run across the ceiling joists at 90 Degrees glued and fixed into place at 250mm centres.
SUPABOARD is an excellent wet area lining material and suitable for direct tiling. SUPABOARD can be butt joined and sealed with Glo mastic or Bostic seal & flex polyurethane mastic. Use Supaprime before applying the tyle adhesive system of your choice. Keep in mind that wet areas require waterproofing to the BCA requirements. Where no tiling is required follow the wall lining installation as a flushed system.
