Wedi Tile Backer Board consists of a blue core made from extruded polystyrene rigid foam which 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.

Wedi Tile Backer Board is suitable for a wide range of applications. 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.

Wedi Tile Backer 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.
