Tile Cracking Prevention - Provides an effective uncoupling layer to neutralize stress between the substrate and tiles, preventing cracking and delamination in ceramic and stone tile installations. Multi-Surface Compatibility - Suitable for various substrates including concrete, plywood, OSB, and gypsum, and compatible with heated floors. Easy to install with thin-set mortar. Moisture Barrier - Made of polyethylene, this membrane protects moisture-sensitive substrates like plywood and OSB, ensuring a durable surface. Sturdy Foundation for Tiles - Features a unique structure that supports and distributes heavy loads evenly, suitable for high traffic areas and heavy furniture. Long-Term Coverage - Backed by a 10-year limited warranty against manufacturing defects when installed per the Schluter Installation Handbook and Technical Data Sheet, following all guidelines and industry standards in effect at the time. Elevate the durability and integrity of your tile installations with the Schluter Ditra Uncoupling and Waterproofing Membrane. Specifically engineered for ceramic and stone tile applications, this membrane offers a revolutionary polyethylene construction that ensures both uncoupling and waterproofing. It stops the common issues of cracked tiles and grout by absorbing the differential movement stresses between the tile layer and the substrate beneath. Additionally, its vapor management capability allows excess moisture to escape. The membrane's column-like mortar structure within the grid cavities promotes excellent load distribution, making it ideal for areas subjected to heavy foot traffic or weight. At only 3.5mm (1/8") thick, it provides a minimal assembly height, reducing transitions to other surface coverings. This product is exclusively for interior use, providing a reliable and effective solution for both dry and wet areas. Founded over 40 years ago by a master tile setter, Schluter Systems pioneered innovative tile and bathroom waterproofing solutions, consistently setting industry benchmarks for quality and durability.
