self-adhesive polymer modified asphalt waterproof coiled material (py polyester tyre construction steel building roof waterproof coiled material

1. Clean the base surface thoroughly.
2. When installing large-area waterproof membrane, the long edge of the membrane should overlap by at least 70mm, and the short edge should overlap by at least 80mm.
3. The short edge joints of adjacent rolls of material should be misaligned by more than 300mm to avoid multiple layers of overlapped joints, which may cause the adhesive to be uneven. Refer to the material overlap for details.
4. When laying on a damp base, the base should be flat and solid, with no standing water.
5. The long edges of the membrane should use self-adhesive edges for overlap, and the short edges should use adhesive tape for overlap. The overlap areas at the ends of the membrane should be mutually offset.
6. When constructing the elevation, mechanical fixation should be performed every 400~600 mm within a 10~20 mm range from the self-adhesive edge of the membrane, and the fixed positions should be covered by the membrane.Please contact customer service for specific matters at 18639026652.
