Basic Waterproofing Membrane- Base Sheet - Two-Ply System - 39 Inchx65 ft.

Prime the substrate with EXTERIOR PRIMER or H2O PRIMER. The first membrane strip should have a width of 50 cm to offset the joints of the first layer with those of the HR FINISH MEMBRANE that will be placed later. Position and unroll the membrane parallel to the edge of the roof, leaving about 8 cm at the front where the gutter will be installed. If the gutter is in place, install the membrane from the roof edge. Remove the underface protective film for a length of about 30 to 40 cm (12 to 15 in), fold this protective film at a 45 degrees angle. attach the exposed part to the support. While applying pressure to the other end of the membrane, gradually pull back the protective film using a scrubbing brush, secure the support membrane to the support while continuing to remove the protective film. First adhere the membrane in the center, and then to each side. Continue applying pressure on the membrane using a heavy roller to ensure adhesion between the support and the membrane and avoiding the formation of bulges, folds or gap The transverse overlap should be 150 mm (6 in) and a longitudinal overlap of 100 mm (3 in). Refer to ROOF SYSTEM INSTALLATION for waterproofing membrane installation to roof details and upstands. Self-adhesive membrane mainly used as an underlay in a two-layer roofing system as well as for waterproofing foundations, shower bases and washrooms. Versatile for a variety of applications Excellent resistance to temperature variations Excellent tear resistance
