Schlüter-KERDI is a crack bridging waterproof membrane made of soft polyethylene, which has been covered on both sides with a special fleece webbing to anchor the membrane in suitable tile adhesive.
Schlüter-KERDI has been developed for bonded waterproofing assemblies with coverings of tiles and natural stone. The waterproofing membrane should be bonded to an even, load bearing substrate with an appropriate tile adhesive. The tiles are laid directly on Schlüter-KERDI using the thin bed method. Other trowel applied covering materials or plaster may also be used.
