Schluter DITRA Matting is a polyethylene membrane with a grid structure of square cavities. Each cavity has dovetail configurations cut in the back and an anchoring fleece laminated to the underside of the membrane for enhanced adhesion. DITRA Matting is 1 metre wide and only 3.5mm thick and provides the thinnest possible layer without sacrificing performance, making it a universal substrate for tile covering. It serves as an uncoupling layer for problematic surfaces, crack bridging, and a waterproofing membrane.

Schluter DITRA Matting can be used for both floor and wall applications on a wide range of surfaces including concrete, mortar screeds, gypsum-based screeds, heated screeds and mixed substrates. DITRA Matting is suitable for use with underfloor heating systems, providing a decoupling layer between the underfloor heating and the tiles. In addition, DITRA Matting also serves as a water vapour pressure equaliser by incorporating a special layer that accommodates moisture occurring underneath the substrate.

The matting is made from non-rotting material and is highly resistant to salts, acids, alkalis, solvents, alcohols and oils. Since the matting is made of waterproof polypropylene, DITRA installations can be made waterproof with minimal effort. Schluter recommends using their Schluter Kerdi Coll Sealing Adhesive and their Schluter Keba Seaming Tape for sealing the seams and floor/wall connections. We cut Schluter DITRA Matting to the length you need it, from 1 metre lengths to 30 metres rolls, meaning you never buy more than you need!

How to install Schluter Ditra Matting

Installing Ditra matting is an easy 3 step process!

1. Make sure that the substrate you're fixing the matting to is clean. The substrate must be free of bond inhibiting components, be load bearing and be even. Any unevenness in the substrate must be levelled prior to the application of Ditra matting.

2. Apply the bonding adhesive to the substrate using a notched trowel. Ardex AF200 is the ideal bonding solution, although anydrate screeds may require additional preparation to ensure the substrate is dry and ready to recieve adhesive. We recommend the Ardex B1 2mm notched trowel for use with decoupling membranes. The adhesive must bond to the substrate and mechanically anchor the fleece on the underside of the Ditra Matting. You can verify the compatibility of all materials prior to installation either with our friendly The London Tile Co customer service team, or with Schluter.

3. Individual courses of Ditra matting should be cut to size. Solidly embed the anchoring fleece on the underside of your matting in the adhesive so that its entire surface is bonded and immediately work it into the adhesive using a float or screed trowel. Please observe the open time of the bonding adhesive. When initially positioning Ditra Matting, it is advisable to align and position the matting while slightly stretching it. Application is made easier with a second person. The side edges and ends of individual courses are cut straight and abutted.

Note: If Schluter Ditra matting is only installed as an uncoupling membrane, side edges and ends of individual courses do not need to be sealed with Schluter Kerdi-Keba tape. Please refer to the instructions for waterproofing if the membrane is to serve as a waterproofing layer.

Once installed, the matting must be protected against heavy mechanical loads to avoid loosening it from the substrate or other damage. It is advisable to place running boards (especially in the centre of material transports) to protect it. Other protective measures, such as shielding of direct sunlight or protection from precipitation in exterior applications, may also be required. Carefully remove any moisture that may have gathered in the indentations of the studs before applying the thin-bed tile adhesive during tiling.

Immediately after Ditra matting is installed, the tiles can be laid and set using the thin-bed method and using a bonding tile adhesive that matches the requirements of the covering. It is recommeded to fill the square cavities with the smooth side of the trowel and to establish a regular pattern in the bonding adhesive with the notched side of the trowel in one application. The tiles are fully embedded in the adhesive. Fully embedded installation of tiles in accordance with the applicable professional standards is particularly important for coverings with high traffic loads and in outdoor areas. The notches of the trowel must match the format and thickness of the tiles, so as to achieve solid bedding. Please observe the open time of your tile adhesive. The adhesive bed over Schluter Ditra matting should not exceed 10mm. For movement joints as control joints, expansion joints, or connection joints please follow the instructions given in the product data sheet as well as the applicable industry regulations.

Note: Thin-bed tile adhesive and the covering materials selected for use with Schluter Ditra Matting must be suitable for the corresponding application and must meet the requirements of the site. Materials used in exterior applications must be waterproof as well as resistant to frost and weather.

Schluter Ditra matting should be used primarily as a waterproofing layer when installing cover materials that are sensitive to moisture (e.g. natural stone or synthetic resin panels) or if moisture is expected to build up on the underside (e.g. in the case of green screed). When Ditra matting is installed in exterior applications, special protective measures may be required; e.g. shielding the installation from direct sunlight. The use of rapid setting thin-bed adhesives may be an advantage for certain projects.

Schluter Ditra matting should be covered with protective running boards if the transport of material makes it necessary to walk over the matting.

Movement Joints

Schluter Ditra matting must be separated at existing movement joints. Movement joints must be continued in the tile covering, as specified by the applicable industry standards. In all other cases, large area floor assemblies installed over Ditra matting must be subdivided into smaller fields with the help of movement joints. The distance between such control joints in exterior applications (balconies and terraces) should not exceed three metres. Depending on the construction of the substrate, field sizes may need to be smaller. Install a corresponding movement joint profile over expansion joints in accordance with the expected movements.

It must be assured that no tension can build at the edge of coverings, e.g. at upright construction elements or floor to wall transitions. The edge profiles and connective joints have to meet the requirements of the corresponding construction standards and must be suitable to prevent the build up of tensions.
