The Schluter KERDI Kereck-F preformed inside corner seals the hardest spot in a KERDI waterproofing assembly — the concave corner where two shower walls meet. Rather than folding sheet membrane by hand and hoping it stays sealed, you set a molded corner that fits the 90-degree angle every time. It is built for tiled showers, tubs, and other wet areas handled by pros and confident DIYers.
Each Kereck-F is molded from KERDI membrane, so it bonds with thinset and ties directly into your KERDI walls and KERDI-BAND seams. This is the inside corner for wall-to-wall junctions, and this pack holds 2 pieces, enough for a single standard shower. Press it into thinset over the membrane and roll out the trapped air.
Pros who build KERDI showers keep these corners on hand. Tile Outlets stocks the Kereck-F corners and the rest of the KERDI system.
