Decoupling movement matting for floor tiling. Suitable for use on most substrates including timber, metal, green concrete and screeds.

Product Description

Schluter Ditra Matting-Decoupling & waterproof membrane

Schluter Ditra Matting Decoupling Membrane is a polyethylene membrane with a grid structure of square cavities, each cut back in a dovetail configuration and an anchoring fleece laminated to its underside.

Schluter Ditra Matting Decoupling Membrane is designed for tile and natural stone installations, and serves as a waterproofing membrane, a vapour pressure equalisation layer to accommodate moisture occurring at the underside of the substrate and an uncoupling layer for problematic substrates.

The substrate must be even and load bearing.

To bond Schluter Ditra Matting Decoupling Membrane, use a bonding adhesive that is appropriate for the substrate. Apply the adhesive using a 3 x 3 mm or 4 x 4 mm notched trowel.

Schluter Ditra Matting Decoupling Membrane uncouples the floor covering from the substrate and neutralises the tensions between the substrate and the tile covering that result from the varying deformations of the materials. Likewise, stress cracks in the substrate are bridged and are, therefore, not transferred to the surface covering.

Schluter Ditra Matting Decoupling Membrane is a waterproof polyethylene membrane with a relatively high vapour diffusion density.

Schluter Ditra Matting Decoupling Membrane protects the substrate against damage due to moisture penetration and aggressive substances.

The interconnected air channels between the cavities on the underside of the Schluter Ditra Matting Decoupling Membrane remain open. This allows moisture in the substrate to evaporate, therefore neutralising vapour pressure.

The bottom of the square cavities in Schluter Ditra Matting Decoupling Membrane, which are filled with thin-bed adhesive, directly transfer the load impact on the tile covering to the substrate. As a consequence, tile coverings installed on top are highly load resistant.

Due to the bonding of the anchoring fleece into the thin-bed adhesive on the underside and the mechanical anchoring of the adhesive in the cut back cavities, Schluter DITRA Matting achieves a good adhesion of the tile covering to the substrate (laboratory test values: ~ 0.2N/mm²).

Schluter Ditra Matting Decoupling Membrane is available in 30m2 rolls or cut to length. To order a custom length, choose ‘1m2’ from the drop down menu above and enter the quantity required.

Designed to cope with the multi-directional lateral substrate movement and provides a stable base for tiling for natural stone and tiles. Summary of functions: Uncoupling, Waterproofing, Equalisation of vapour pressure and Load distribution (load impact). DITRA can be used with KERDI-KEBA to fully waterproof surfaces. Adhere with VS90 Adhesive.
