I. Introduction APF-500 self-adhesive polymer modified bitumen membrane is a kind of polymer modified bitumen and synthetic rubber as the base material, adding active additives, polyester tire reinforcement layer, poly ethylene as the surface material, the use of silicone release underside release paper / film, with cold self-adhesive, cold construction operations, environmental protection waterproof membrane. Second, the performance of a product, excellent waterproof performance. 2, excellent high temperature performance and low temperature flexibility. 3, waterproof layer crack resistant to puncture resistant ability. 4, excellent resistance to UV weathering long life. 5, strong grassroots adhesion, good adhesion with a variety of substrates can be damaged due to the leakage of membrane locking in the local area, to effectively prevent channeling of water. 6 qualitatively good, has good chemical resistance, simple construction, pressure sensitive adhesive, waterproof effect lasting stability. Third, the construction method Primary treatment: primary surface to reach solid, smooth, clean, dry requirement, and no sharp projections, all the holes with cement mortar must fill level. With a brush or brush on the first coat of qualified primary supporting primary treatment agent before laying APF-500 self-adhesive membrane after let it dry completely. According to the grassroots shape, flexible positioning, the self-adhesive membrane adjacent membrane facing straight down and expand, the length of the side lap width shall comply with the relevant national standards, then the coil from both ends toward the middle of the rolled up; When laying the membrane, torn paper isolated, so self-adhesive surface and substrate surface to form a good initial adhesion. With a press roll with a uniform pressure sufficiently lap roll, to ensure complete adhesion between the web to form an integral closed and continuous effect. Four, coil precautions after construction, to be done after the acceptance of the protective layer. Dry shop law requires the construction of grass-roots level, dry, and primary treatment agent with a special membrane laying completed primary treatment and after inspection, should be protected as soon as possible, so that from exposure and physical damage. For damaged parts breakage surfaces shall be clean. By APF-500 self-adhesive polymer modified bitumen membrane repair, and the surrounding lap width of not less than 100 mm.
