WATERPROOF TILE UNDERLAYMENT MEMBRANE – This uncoupling membrane for tile creates a moisture barrier over the subfloor, helping protect tile floors in bathrooms, showers, kitchens, and other wet areas from water penetration. CRACK ISOLATION & ANTI-FRACTURE LAYER – The tile underlayment membrane absorbs in-plane subfloor movement to help isolate cracks and reduce stress transfer to the tile above, supporting more durable, longer-lasting installations. POLYPROPYLENE (PP) & HDPE CONSTRUCTION – Made with polypropylene and high-density polyethylene, this tile membrane bonds well to thin-set mortar over both concrete and wood subfloors and stays flexible where the floor moves. EASY TO CUT & INSTALL – Lightweight uncoupling membrane for tile floor that cuts with a utility knife and sets in standard thin-set mortar, making it simple to fit around corners and fixtures for DIY or professional use. WHOLE-ROOM COVERAGE – Each roll covers 150 sq ft (3.3 x 45.9 ft) with clearly labeled square footage, sized for a full bathroom, kitchen, or mid-size floor with minimal seams.
