Schluter KERDI BOARD is a multifunctional tile substrate for wall areas, which can be used for creating bonded waterproofing assemblies with tile coverings. Additionally, the product has many uses as a structural panel.

Schluter KERDI BOARD covers a broad range of application areas for creating level, waterproof substrates for the installation of ceramic and natural stone tiles. With suitable preparation of the joint areas, the structural panel may be used for officially approved bonded waterproofing assemblies.

Schluter KERDI BOARD is made from an extruded XPS hard foam, with a cement-free reinforcement layer laminated onto both sides, together with an anchoring fleece webbing. The surface of the board has gridlines consisting of 10 x 10 mm squares printed on one side. This board is waterproof and can withstand all chemical stresses that typically occur in conjunction with tile coverings. This board may be used in bonded waterproofing assemblies where required.

Schluter KERDI BOARD is available in two different panel sizes: 1250mm x 625mm (0.78m²) or 2600mm x 625mm (1.62m²). These panels are available in thicknesses of 5, 9, 12.5, 19, 28, 38 and 50 mm.

Schluter KERDI BOARD is suitable for: creating tile substrates on green masonry, existing substrates of all kinds and stud frames made of wood or metal; creating straight or curved (KERDI BOARD V) separating walls; concealing wall mounted installations and piping (pipe boxes – KERDI BOARD E/U); creating straight or curved (KERDI BOARD V) bathtub and shower surrounds; as well as creating work surfaces, vanities, storage shelves (KERDI BOARD Niche) or any other bathroom structures. The material is equally suitable for creating level substrates in floor renovation projects e.g. residential bathroom installations designed for foot traffic.

Schluter KERDI BOARD is simply cut to size with a utility knife. The gridlines printed on the surface are helpful for neat and quick installation. Panels can be fully adhered in wall areas or alternatively attached with dabs of adhesive. If necessary, the material may be secured with additional wall anchors. In the case of stud frames made of wood or metal, the panels are attached with screws and washers.

To create fully waterproof areas, all seams and joins in the Schluter KERDI BOARD must be fully covered with the seaming tape Schluter KERDI KEBA (minimum width 12.5 cm), embedding it in the sealing adhesive Schluter KERDI COLL L. The seaming tapes should have at least 5 cm of overlap. Schluter KERDI KEBA band is also suitable for creating functional connections to fixed structural elements such as door openings or windows of metal, wood or plastic. For this purpose, apply Schluter KERDI FIX on the adhesive area of the fixed structures and Schluter KERDI COLL L on the adhesive area of the board and cover the entire joint area with sealing band.

Tiles can be installed directly over Schluter KERDI BOARD using the thin-bed method, but other suitable trowel applied coverings or plaster layers can be utilised, please contact us for advice.
