Schluter KERDI-FIX sealing and bonding compound is the white adhesive-sealant that bonds and seals KERDI waterproofing membrane at the connections standard thinset can't handle — pipe penetrations, drains, and material transitions. Pros keep a tube in the bag for details that have to stay sealed.
This 290ml cartridge fits a standard caulk gun and bonds KERDI to metal, PVC, tile, and other hard surfaces, closing the seams and edges the membrane leaves open. The white color blends with light grout and finished surfaces where the bead may show.
