1. Product Description WATER-STOP is a thin load bearing, bonded, sheet membrane for waterproofing applications. Installed using an appropriate thin-set mortar and with the W-S waterproofing accessories; bands, tapes, corners and collars, is a complete assembly bonding together to create a watertight layer to protect the structure and the tile installation from moisture and minor substrate cracking. 1.1. Material Working Properties WATER-STOP is a highly-flexible polyolefin sheet membrane 0.02” (0.

fashion. Avoid cross-lapped seams and seams over drains, protrusions etc. Use chalk lines to maintain sheet alignment. Sheet may be pre-folded and cut to accommodate upturns and other requirements per industry guidelines and specifications. 3.3. Treat Connections to Fixed Building Elements & Joints Treat all elements such as expansion joints, penetrations and floor gully connections using the W-S Waterproofing Accessories. All flashings and penetrations of pipes, conduits, fixtures, etc.
- To seal between the drain and the underside of the membrane Apply 2 beads of Urethane sealant or MS Polymer sealant separated 2'' in concentric circles around the drain hole opening and a third drop interposed there between in a zigzagged pattern. - Install the WATER-STOP membrane. Apply pressure to the membrane with the flat side of the trowel squeezing the sealant toward the drain hole and the thin-set mortar outward toward the sheet edges or the perimeter of the shower.
The WATER-STOP installation for waterproofing must start laying the first sheet at the lowest point and then overlap the next layer. Apply the membrane to the entire floor surface and up the walls. WATER-STOP should be turned up wall a minimum of 2 inches and at least to flood point. 3.4.2. Walls Treat pipe penetrations and mixing valves with W-S TUBO. Start in a corner and work your way out from the corner to the edge of the installation. Apply the thin-set to the surface. Install the first length.
3.7.1. Urethane sealant or MS Polymer Sealant Urethane sealant or MS Polymer sealant must be applied with a commercial grade caulk gun. Beads must be continuous without skips or voids. Beads must be continuous without skips or voids. At 1/2’’ from edge of sheet being overlapped apply two 1/8’’ beads separated 2'' and a third bead interposed there between in a zigzagged pattern. Close and flatten pressing with flat edge of trowel. Seams must be allowed to cure to develop strength.
