Our take on the Kerdi-Fix Sealing/Bonding 290Ml Grey

Kerdi-Fix is a single-component sealing and bonding compound made by Schluter, sold in a 290 ml cartridge in grey. It is solvent-free and odor-neutral, bonds to wood, stone, concrete, metal and glass, and resists UV and weather. Its main job is sealing joints and penetrations in Schluter-KERDI shower and bath waterproofing, where it bonds to the membrane. Against ordinary caulk it holds up better outdoors and on wet assemblies, but it is a specialty product with a narrow role and a higher cost than generic sealant.

Questions and answers

What is Kerdi-Fix used for?
It seals and bonds joints, corners and penetrations in Schluter-KERDI waterproofing, and bonds the membrane to drains, niches and valves. It also works as a general sealant on wood, stone, concrete, metal and glass.
Does it work without KERDI membrane?
Yes. It bonds to common building materials on its own, but its main purpose is sealing KERDI assemblies in showers and baths.
Is it safe on foam boards and plastics?
It contains no solvents, so it will not attack polystyrene foam boards or most plastics the way solvent-based adhesives can.
Can it be used outdoors?
Yes. It resists UV rays and weather, so exterior joints and wet areas hold up better than with standard caulk.
How is it applied?
It comes in a 290 ml cartridge and goes into a standard sealant gun. No mixing is needed.
Will the grey color match my tile?
It is a mid-grey, so it blends with grey grout and stone but shows against white or light tile.
