Masterboard

Masterboard is a Class 0, Class 1 fire protection board manufactured by Promat and is a versatile building board with limited combustibility. Due to its inherent properties Promat Masterboard is an effective passive fire protection building board. Promat Masterboard is a building board manufactured from calcium silicate and fibre reinforced. Masterboard Fire protection boards are off white in colour and has one smooth face and one sanded face. It can be left undecorated or painted, tiled or wallpapered as required. Promat Masterboard is moisture resistant and will not deteriorate in damp and humid environments and is thus suitable for use in semi external and internal applications. Masterboard Fire Protection Boards are available in 6mm, 9mm and 12mm  thicknesses and in 2440 x 1220mm sheet sizes.

Masterboard Fire Protection boards, due to their limited combustibility and Class 1 rating with regards surface spread of flame, have a number of applications where both fire protection and durability are required. These include fire rated timber and metal stud partitions and ceilings;  swimming pool ceilings; wall and roof linings; soffit, porch and canopy linings; service ducts and pipe covers; boiler cupboard and airing cupboard linings; timber door upgrades.

All calcium silicate boards including Masterboard, have a high suction and thus it can be difficult to plaster. If a plaster finish is required, a sealer coat must first be applied. This should be a diluted PVA or primer coat made up of 5 parts water, 1 part PVA. A bonding coat of PVA should then be applied made up of 3 parts PVA and 1 part water, and then finally a 5mm thick skim coat of plaster should be applied while the bonding coat is still wet and sticky. If paint decoration, wallpapering or tiling to the Masterboard building boards is required, again a primer coat should first be applied to ensure the effective application of the required decorative finish.
