Schluter DILEX-KSA Perimeter Joint Movement Profiles

Application and Function

Perimeter joints are provided at restraining elements to accommodate movements attributable to changes in moisture, temperature, and loading. Schluter-DILEX perimeter movement joints are specifically designed to provide the flexible connection of tiled surfaces to fixed building elements.

Schluter-DILEX-KSA features a trapezoid-perforated anchoring leg made of stainless steel, which is secured in the mortar bond coat and provides edge protection for adjacent tiles, and a self-adhesive backing strip that can be bonded to fixed building elements (e.g., door and window frames, bathtubs and shower trays, countertops, etc.).

The profile isolates the tile covering from the structure and accommodates movement via the 3/8" (10 mm) -wide, soft thermoplastic rubber movement zone, which also forms the visible surface. The thermoplastic rubber movement zone can be replaced if damaged. Schluter-DILEX-KSA uses the same anchoring leg as Schluter-DILEX-KSN to allow for the same appearance throughout an installation.

DILEX-KSA also prevents sound bridges, making it ideal for transitions in sound-rated floors.

  1. Select DILEX-KSA according to tile thickness.
  2. Using a notched trowel, apply thin-set mortar over the area where the profile is to be placed.
  3. Remove film from self-adhesive backing strip on DILEX-KSA.
  4. Press the perforated anchoring leg of the profile into the mortar and adjust it securely against the existing building elements.
  5. Trowel additional thin-set mortar over the perforated anchoring leg to ensure full coverage and support of the tile edges.
  6. Solidly embed the tiles and align flush with the top of the profile.
  7. A joint of approx. 1/16" - 1/8" (1.5 mm - 3 mm) should be left between the tile and the profile.
  8. Fill the joint completely with grout or setting material.


Schluter-DILEX-KSA is available with a stainless steel anchoring leg. All profiles feature a thermoplastic rubber movement zone.

In special cases, the suitability of a proposed type of material must be verified based on the anticipated chemical, mechanical, and/or other stresses.

The thermoplastic rubber movement zone is resistant to most chemicals commonly encountered in tile environments.

The stainless steel anchoring leg is manufactured using 304 (1.4301 = V2A) or 316 L (1.4404 = V4A) stainless steel. Stainless steel can sustain high mechanical stresses and is especially well suited for applications requiring resistance against chemicals and acids.


Schluter-DILEX-KSA requires no special maintenance or care and is resistant to mold and fungi. Clean profile using common household cleaning agents.

Stainless steel surfaces exposed to the environment or aggressive substancesshould be cleaned periodically using a mild household cleaner. Regular cleaning maintains the neat appearance of stainless steel and reduces the risk of corrosion. All cleaning agents must be free of hydrochloric and hydrofluoric acid. Stainless steel surfaces develop a sheen when treated with a chrome polishing agent.

The thermoplastic rubber inserts in DILEX-KSA are replaceable.
