Schluter-KERDI is a bonded waterproof membrane with limited crack-bridging capabilities. It is made of soft polyethylene, which is covered on both sides with a special fleece webbing to anchor the membrane in the thin-set mortar.
Schluter-KERDI was developed as a waterproofing membrane to be used in conjunction with ceramic and stone tile coverings. Tiles can be installed directly on Schluter-KERDI using the thin-bed method. Other trowel-applied covering materials, such as plaster, can also be used.
Pre-cut sections of Schluter-KERDI are available for inside and outside corners, as well as for pipe collars. Use Schluter-KERDI-BAND, in widths of 5" (12.5 cm), 7-1/4" (18.5 cm), or 10" (25 cm) to seal butt joints or corner joints. Schluter-KERDI-FLEX, in 5" (12.5 cm) or 10" (25 cm) widths, is used to seal expansion joints or flexible edge joints.
Schluter-KERDI is a polyethylene waterproofing membrane with a very high steam-diffusion density. The material is physiologically safe. Schluter-KERDI requires no special disposal.
Schluter-KERDI is waterproof and resistant to most chemicals commonly encountered in tiled environments. It is resistant to aging and will not rot. Schluter-KERDI is highly resistant to saline solutions, acid and alkaline solutions, many organic solvents, alcohols, and oils. Information regarding its resistance to specific substances can be provided if concentration, temperature, and duration of exposure are known. For acid-resistant coverings, use an epoxy adhesive to set and grout the tile.
Schluter-KERDI is suitable for wall and floor surfaces where protection against the penetration of moisture or other harmful substances is necessary. Surfaces include showers, tub surrounds, and areas surrounding swimming pools. Industrial applications include the food industry, breweries, and dairies. Before placing the Schluter-KERDI, verify that the substrate is clean, even, load bearing, and free from moisture. Surfaces that inhibit proper adhesion must be removed or appropriately treated.
