Application and Function

Schlüter®-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.

It consists of an extruded hard foam panel, with a special reinforcement material on both sides and fleece webbing for effective anchoring in the tile adhesive. With the available panel thicknesses of 5, 9, 12.5, 19, 28, 38 and 50 mm, Schlüter®-KERDI-BOARD covers a broad range of areas of use for creating level, waterproof substrates for the installation of ceramic and natural stone tiles.

Schlüter®-KERDI-BOARD is waterproof and can withstand all chemical stresses that typically occur in conjunction with ceramic tile coverings. Where required, an approved bonded waterproofing assembly can be created with Schlüter®-KERDI-BOARD in specific areas.

Schlüter®-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 separating walls; concealing wall mounted installations and piping (pipe boxes); creating straight or curved bathtub and shower surrounds; as well as creating work surfaces, vanities, storage shelves 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.

Schlüter®-KERDI-BOARD is simply cut to size with a utility knife. The gridlines printed on the surface are helpful for neat and quick installation.

Schlüter®-KERDI-BOARD 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, Schlüter®-KERDI-BOARD is attached with screws from the matching hardware system.

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

Schlüter®-KERDI-BOARD-N prefabricated installation elements are available for the creation of niches and storage surfaces in walls with a column structure.
