This waterproofing membrane is intended for showers, bathrooms, kitchens, saunas, and other wet areas. The high-density polyethylene construction creates a durable moisture barrier. A fleece layer on both sides allows the membrane to be embedded into unmodified thin-set mortar, forming a strong bond with tile substrates. The material can be cut and folded to fit corners, pipes, or irregular surfaces. When installed correctly, the membrane helps prevent water from reaching cement boards, wood subfloors, or existing tiles. This reduces the potential for mold growth and material degradation. The polyethylene core resists aging for consistent performance. The membrane works with ceramic, porcelain, marble, stone, and other tile types. It is also compatible with radiant heating systems where allowed. Floor applications include concrete slabs and plywood subfloors. Wall applications include shower surrounds, tub enclosures, and kitchen backsplashes. The product works for new construction and renovation projects. Unlike liquid membranes, this sheet membrane provides a uniform thickness. Installation requires spreading thin-set mortar with a notched trowel, positioning the membrane, and rolling it for full contact. After the mortar cures, tile can be installed directly over the membrane. Seams between rolls can be overlapped with mortar. Sheet membranes do not need drying time or multiple coats.
