Schlüter®-KERDI-BOARD | Material | Schlüter-Systems



Schlüter®-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.

Material properties and areas of application

Schlüter®-KERDI-BOARD is waterproof and can withstand all chemical stresses that typically occur in conjunction with tile coverings. Schlüter®-KERDI-BOARD may be used in bonded waterproofing assemblies where required.

Schlüter®-KERDI-BOARD is completely level and remains free of distortions and decay. It will not rot and is highly stable, even with one side exposed to temperature fluctuations and moisture.

Schlüter®-KERDI-BOARD can be used for a multitude of different applications. In special cases, the suitability of the material must be verified based on the anticipated chemical and mechanical stresses. The information provided below is intended as general guidelines.

Substrates on which Schlüter®-KERDI-BOARD is to be installed need to be evaluated for their stability and other project specific requirements. Before directly adhering the panel with tile adhesive, remove all surface components that may weaken the bond. Otherwise, we recommend attaching the panel with additional fixings.

Select a suitable material thickness if using Schlüter®-KERDI-BOARD for the construction of non load bearing/free-standing partition walls, shelving or similar structures and use reinforcement profiles as necessary. The use of Schlüter®-KERDI-BOARD in floor assemblies is restricted to foot traffic areas, e.g. bathrooms, kitchens, etc. Floor coverings may have a certain hollow sound when they are walked upon with hard shoes or tapped with a hard object.

Select the material thickness and installation method depending on the evenness of the substrate. Thin panels of Schlüter®-KERDI-BOARD (5 mm) should be fully embedded in tile adhesive.
