- Pre-formed 90° outside corners that complete the KERDI waterproofing at exposed exterior angles — curb corners, wall edges, and neo-angle openings.
- Same 4 mil KERDI material as the sheet membrane, pre-formed so it sits tight against transitions without rounding or voids.
- 2-pack; works with KERDI, KERDI-BOARD, and DITRA systems — typically used alongside KERDI-KERECK inside corners to waterproof the full curb perimeter.

Description
Description
Outside corners — where two wall planes meet facing outward — are tricky to waterproof cleanly with flat membrane. The KERDI-KERECK outside corner takes the guesswork out: it's a preformed, seamless piece that sets perfectly every time.
Made from the same KERDI waterproofing membrane material, these one-piece corners bond directly into your thin-set layer and provide a continuous, leak-proof seal at outside corner transitions. Compatible with KERDI, KERDI-BOARD, and DITRA shower assemblies.
Pro Tip: Use inside and outside corners together as a set — buying both upfront means you won't be back-ordering mid-install. For a standard walk-in shower conversion, you'll typically need 2–4 inside corners and 2 outside corners depending on the layout. Grab extras now; they're cheap insurance on a tile job you don't want to redo.
Pack includes 2 outside corners.

The product details online were thorough enough that my installer didn't have any questions when it showed up. That saved us time on-site. Happy with the whole experience.
