Schluter®-KERDI-SEAL-Pipe Seal (PS) and -Mixing Valve (MV) prefabricated seals are sections of the Schluter®-KERDI waterproofing membrane with overmolded rubber gaskets. KERDI-SEAL-PS is designed to seal pipe protrusions through the KERDI waterproofing membrane. KERDI-SEAL-MV protects moisture-sensitive solid backing panels at the mixing valve. The Schluter®-Shower System is a bonded waterproofing system for tiled showers, steam showers, and bathtub surrounds. It is an integrated family of products that creates a sealed system to eliminate leaks and reduce the potential for efflorescence and mold growth. Schluter®-KERDI-SEAL-PS and -MV complement the Schluter®-Shower System by providing reliable solutions to address typical protrusions through the KERDI membrane, such as showerheads, tub spouts, steam inlets, and mixing valves.
