General Product Information
• Product should be delivered to site a minimum 48 hours prior to installation and stored in the environment of where it is to be installed to allow it to acclimatise.
• The framing must be straight and true.
• For Wall & Ceiling applications framing can be placed at 600mm centres or less. We recommend for ceilings, framing placed at 450mm.
• Easycraft wall linings can be joined off the studs but these joins must be supported by additional noggins at 450mm maximum spacing.
• Fixings should be positioned no closer than 25mm to a corner and no closer than 15mm to the edge. This positioning will prevent splintering and breakout.
• A 10mm gap must be left at the floor if the wall lining is being installed only part way up the wall.
• A 5mm gap must be left at the top of the sheet if the wall lining is being installed from floor to ceiling.
• A 0.5mm expansion gap should be allowed at each join. Do not ‘Hard Knock’ the panels together.
• For each metre width of wall or ceiling, allow approx. 1.0mm for an expansion gap at the outer perimeters of your wall or ceiling. (e.g. 6m wall x 1.0mm = 6mm therefore leave a 3mm gap at each outer edge of wall or ceiling)
• Decide how you wish to finish off internal and external corners before you install the first sheet.
• Where an internal wall lining is backing onto an external wall we recommend the back surface of the wall lining be undercoated with a paint primer.
• When installed as a ceiling lining the back of the sheet should be undercoated prior to installation. We recommend for ceiling applications that you DO NOT end butt sheets due to the potential for movement and seeing the join.
• For high moisture areas, bathrooms, laundries and semi exterior use, we recommend using our ‘Wet Area Interior’ product, indicated with a Blue Tongue Joiner.
These are recommendations only. Always consult with a local Registered Builder experienced in the use of these types of products and to ensure you comply with all relevant building regulations.
Pre-conditioning of boards prior to installation
Pre-conditioning MDF boards is recommended to ensure that they attain an equilibrium moisture content (EMC) before fixing, so as to reduce the likelihood of bowing or shrinkage after they have been fixed. Some boards may achieve an EMC simply by being stored for some time in the location where they are to be used without any positive conditioning. Never store material outdoors or in an open area (veranda) or areas with newly poured concrete or in rooms that have been recently plastered. Always try to store the board in the area that they are to be used on gluts lifted up off the floor and let acclimatise.
MDF MR Material
As with solid wood, MDF is a hygroscopic material (meaning it readily takes up and retains moisture), thus its moisture content depends on the relative humidity and air temperature in the surrounding environment. As the moisture content of MDF changes, it is subject to dimensional changes.
There are many variables which can ultimately affect the performance of timber, including the surrounding environment, quality of installation and quality of framing. But managing changes in the environment humidity levels and moisture content plays a very important role in achieving the best results from the product. In environments that can experience large changes in air temperature and humidity you may experience movement in the panels, either expansion or shrinkage.
