Schlüter®-DITRA is a polyethylene membrane with a grid structure of square, cut-back cavities and an anchoring fleece laminated to its underside. In conjunction with tiled coverings, Schlüter®-DITRA forms an uncoupling, waterproofing, and vapor pressure equalization layer.

Designed for ceramic tile and dimension stone installations, Schlüter®-DITRA serves as an uncoupling layer for problematic substrates, a waterproofing membrane, and a vapor pressure equalization layer to accommodate moisture occurring at the underside of the substrate.

To bond Schlüter®-DITRA, use a bonding mortar that is appropriate for the substrate. Apply the mortar using a 1/4" x 3/16" (6 mm x 4.5 mm) V-notched trowel. The anchoring fleece on the underside of Schlüter®-DITRA must be fully engaged in the mortar to provide a mechanical bond to the substrate. Using the thin-bed method, set the tile covering directly on the Schlüter®-DITRA in such a way that the tile adhesive becomes mechanically anchored in the square, cut-back cavities of the Schlüter®-DITRA matting. Schlüter®-DITRA is also suited as a support matting for covering materials such as stucco, plaster, or screed.

To find your square footage:  Multiply the lengh x width of the area you want to cover.   Example: An area 3 feet wide and 3 feet long would be 9 square feet.  3x3=9
