Schlüter-DILEX-BWS  PVC movement joint profile

Schlüter-DILEX-BWS is a pre-fabricated plastic movement joint profile for installation in tiled coverings. The perforated anchoring legs, made of recycled rigid PVC, are secured in the tile adhesive beneath the tiles where they transmit occurring movements to the movement zone (the upper movement zone is also the visible surface).

The movement zone absorbs compressive, tensile, and shear stresses. The soft CPE movement zone and visible surface is only 5 mm wide, matching common grout joint widths.

Consequently, the smaller width absorbs relatively limited movements; this should be taken into account when evaluating the requirements for a specific application. DILEX-BWS is particularly suited as a movement joint for tile coverings installed over Schlüter-DITRA.

If larger movements within the covering are anticipated, installation of Schlüter-DILEX-BWB, with a 10 mm movement zone, is recommended.

In addition to residential applications, DILEX-BWS can also be installed in areas with moderate traffic loads, such as offices or salesrooms. The profile is also suited for exterior use.

1. Select Schlüter-DILEX-BWS according to the tile thickness.
2. Apply tile adhesive to the area where the profile is to be installed, using a notched trowel.
3. Press the perforated anchoring legs of DILEX-BWS into the tile adhesive and align. The profile must align with movement joints in the substrate.
4. Trowel additional tile adhesive over the trapezoid perforated anchoring leg to ensure full coverage.
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 approx. 1 mm lower). Full coverage must be obtained between the tile and the profile’s anchoring leg.
6. A joint of approx. 2 mm should be left between the tile and the profile.
7. Completely fill the space between the tile and the profile with grout.
   Since cement-based grouting materials cannot establish a lasting bond with synthetic materials, cracking of the profile joint cannot be ruled out.

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

Material properties and areas of application

The material is resistant to most chemicals commonly encountered in tiled environments and is formulated to inhibit fungi and bacteria growth.

In special cases, the suitability of materials must be verified based on the anticipated chemical, mechanical, and/or other stresses. The CPE movement zones of the profile are UV resistant and free of plasticisers.

DILEX-BWS is a movement joint profile for tile coverings set in the thin bed method. The profile must align directly over the existing movement joints in the substrate. It is not suited for use above structural expansion joints.
