3 ft. 3 in. x 45 ft. 9 in. DITRA Uncoupling Membrane (150 sq. ft. Roll) | SHL-DITRA150

Schluter's DITRA Uncoupling Membrane is made of polyethylene with a grid structure of square cavities, each cut back in a dovetail configuration, and an anchoring fleece laminated to the underside. The anchoring fleece is embedded in thin-set mortar to provide a mechanical bond to the substrate. Tile is installed over DITRA using the thin-bed method in such a way that the mortar becomes mechanically anchored in the square, cutback cavities of the matting. Designed specifically for ceramic tile and dimension stone installations, DITRA serves as an uncoupling layer, waterproofing membrane, and vapor management layer that accommodates moisture from beneath the tile covering.
