USG Durock Shower System Waterproofing Membrane

USG Durock Shower System Waterproofing Membrane (0.12" thick) is perfect for waterproofing custom walk-in showers where ceramic, porcelain, or natural stone will be installed. The waterproofing underlayment provides a completely waterproof barrier between the substrate and the installed tile when it is applied to code-approved substrates with unmodified thinset mortar. This membrane is a vapor retarder that is thin, pliable, and extremely durable. 150 square foot rolls measure 36" wide x 50' long and is installed using a 3/16" x 3/16" V-Notch, or 1/8" x 1/8" Square or U-Notch Trowel.The membrane is an innovative membrane that features an oriented HDPE, cross-laminated core that provides strength and tear resistance at much thinner mil thicknesses (12 mil), making it the most pliable, user-friendly membrane in the industry, with the least amount of buildup at seams. It also has an extremely low permeability rating (<0.075 perms per ASTM E96 Procedure E), making it ideal for wet areas, including continuous-use steam showers. This product is suitable for waterproofing floors, walls and countertops.
