Schluter DITRA & DITRA XL - Uncoupling Membranes

DITRA & DITRA XL Membranes are uncoupling and waterproofing membranes that are recommended for any even and load-bearing substrate such as: plywood and OSB; 24" o.c. truss and I-joist systems; green concrete; gypsum-based screeds; pre-stressed and post-tensioned concrete; and radiant-heated floors. For most tile installations, Schluter - DITRA / DITRA XL eliminates the need for a second layer of plywood or for the use of the cementitious backer-board. Schluter DITRA / DITRA XL ensures a lasting installation by allowing independent movement between the tile covering and the substrate. This eliminates the transfer of stresses from the substrate to the tile covering. In addition, These Schluter-DITRA Membranes are lighter, thinner, and easier to apply than any other underlayment.

Schluter Ditra and Schluter Ditra XL Feature:

• Exclusively designed for ceramic and stone tile surfaces
• Neutralizes stress between the subfloor and tile surface, eliminating the main cause of cracking
• Waterproofs and allows moisture in the substrate to evaporate
• Allows ceramic tile installations over single-layer plywood (at least 5/8" thick over 16" o.c. floor joists), eliminating the need for a second sheet of plywood or backer-board
• Ideal for interior and exterior tile and stone installations
• DITRA: 1/8" x 3' 3"
• DITRA XL: 5/16" x 3' 3"
