Schluter Kerdi-band 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-band 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.
 

Schluter Kerdi-Band is sold in different sizes.
