  • 90° Outside corner

Variant: DIADEC 


Schluter®-DIADEC-K is a variant of the DIADEC profile without an anchoring leg. It features an open cavity that is filled with thin-set mortar to secure the profile in the assembly. DIADEC-K is installed in wall applications (e.g., wainscotings and bases) with coverings at least 1/4" (6 mm) thick. The profile is particularly suited for finishing edges in retrofit applications, such as tile installation over existing wall tiles.

Note: The outside corner can be used with any size of the DIADEC profile.


1. DIADEC-K may be used to cover assembly edges at least 1/4" (6 mm) thick.

2. Fill the profile cavity with thin-set mortar.

3. Using a notched trowel, apply thin-set mortar to the area where the profile is to be placed.

4. Press the profile into the mortar and align. Leave a space of approximately 1/16"-1/8" (1.5 – 3 mm) between the profile and tile.

5. Fill joints completely with grout or setting material.

6. Work with materials and tools that will not scratch or damage sensitive surfaces. Setting materials must be removed immediately.

Note: Corners/end caps are held in place with thin-set mortar. Fill the ends of the profile with thin-set mortar prior to inserting the accessories.


The Schluter®-DIADEC-K profile requires no special maintenance or care and is resistant to mold and fungi. Clean profile using common household cleaning agents. All cleaning agents must be free of hydrochloric and hydrofluoric acid. Do not use abrasive cleaning agents.
