Description 12.5mm wedi Board 1250mm x 600mm is a specific sized wedi tile backer board that measures 1250 x 600 x 12.5mm. It consists of a blue polystyrene foam core made from extruded rigid foam. The rigid foam is reinforced with glass fibre (with alkali-resistant finish) on both sides and coated with a polymer-modified cement. This core is 100% waterproof and remains fully functional even after possible damage. 12.5mm wedi Board is suitable for a wide range of applications, thanks to it’s special properties. It is primarily used as a carrying element for laying tiles, slabs and natural stone floor coverings using the thin-bed method. It can also be used as an adhesive surface for applying plaster, tile adhesive and other materials. 12.5mm wedi Board offers excellent moisture protection, effective heat insulation, and can be used in countless ways as a design element in any tiling installation. It is approved for interior use in rooms at a normal temperature. Contact wedi on the application method for special applications (swimming pools, cold stores, external areas etc.). The boards are approved for use on floors in rooms with an ordinary residential load. Wheeled loads with high concentrated loads are not permitted. 12.5mm wedi Board can be fitted on almost any surface, and is waterproof, heat-insulating, versatile, lightweight, dimensionally stable and quick to process. wedi Fixing Dowels, wedi Board Connectors and wedi Fixing Washers can be used to fix the boards to substrates such as studwork, wooden floors and solid walls/floors. Use wedi Sealing Tape, Corners & Sealing Gaskets along with wedi 520 Waterproofing Membrane and wedi 610 Adhesive to seal joints between boards, internal and external corner junctions and around protruding pipes.
