Schluter DILEX-BWS Surface Joint Profiles

Application and Function

Surface joints must be placed within the tiled surface regardless of substrate conditions. They provide stress relief from movements in the tile field due to thermal and moisture expansion/contraction and loading.

Schluter-DILEX-BWS is a prefabricated, maintenance-free surface movement joint profile. It features trapezoid-perforated anchoring legs, made of recycled rigid PVC, which are secured in the mortar bond coat and provide edge protection for adjacent tiles. The profile separates individual fields in the tile covering and accommodates movement via the soft chlorinated polyethylene (CPE) movement zone, which also forms the visible surface.

The movement zone is only 3/16" (5 mm) wide, matching common grout joint widths. The profile absorbs relatively limited movements, given the width of the movement zone. This should be taken into account when evaluating the requirements for a specific application.

If larger movements within the covering are anticipated, the Schluter-DILEX-BWS may be installed with greater frequency to create smaller fields, or the Schluter-DILEX-BWB (3/8" (10 mm) movement zone) may be used.

Schluter-DILEX-BWS is suitable for both residential and medium-duty commercial applications, such as offices and stores, subject to light mechanical loads (e.g., offices and stores). The profile is also suited for exterior use.

  1. Select Schluter-DILEX-BWS according to tile thickness.
  2. Using a notched trowel, apply thin-set mortar over the area where profile is to be placed. The profile must align directly with movement joints in the substrate below.
  3. Press the perforated anchoring legs of the profile into the mortar and align.
  4. Trowel additional thin-set mortar over the perforated anchoring legs to ensure full coverage and support of the tile edges.
  5. Solidly embed the tiles so that the tiled surface is flush with the top of the profile; the profile should not be higher than the tiled surface, but rather up to approximately 1/32" (1 mm) lower.
  6. A joint of approximately 1/16" - 1/8" (1.5 mm - 3 mm) should be left between the tile and the profile.
  7. Fill the joint completely with grout or setting material.


Schluter-DILEX-BWS consists of lateral perforated anchoring legs and side sections made of recycled rigid PVC, connected by top and bottom movement zones made of soft CPE.

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

Schluter-DILEX-BWS is resistant to most chemicals encountered in tiled environments. The profiles CPE movement zones are UV-resistant and contain no softeners. The CPE material is also resistant to a number of acids, alkalis, oils, greases, and solvents.


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