Schluter Kerdi Waterproof Membrane




Schluter Kerdi Waterproof Membrane is a flexible, sheet waterproof membrane. Schluter Kerdi Waterproof Membrane features a modified polyethylene core with non-woven polyproplyene on both sides to anchor the membrane in thin-set mortar. Kerdi was developed as a waterproofing membrane to be used with ceramic and stone tile coverings. Tile can be installed directly on Schluter Kerdi using the thin-bed method. Other trowel-applied covering materials, such as plaster, can also be used. Schluter Kerdi Membrane is available in custom sizes of 10 sqft – 323 sqft.

Kerdi has been evaluated according to the “Standard Method for the Testing and Evaluation of Volatile Organic Chemical Emissions from Indoor Sources Using Environmental Chambers, Version 1.1” for California Specification 01350 and found to comply with the VOC requirements. California Specification 01350 is referenced by various green building standards and rating systems.
