Polysulfide sealant waterproof products and construction methods: primary treatment: must be neat with sticky surface (available portable cutting machine, grinding wheel, steel brush), the coating surface exposed structure layer firmly. The joint surface must be completely dry, clean, no frost. All the surface dust and cement slurry must be brushed clean rust and paint. The protection of metal surfaces are also removed. Such structures are not available. The first drying dry, blowtorch primer coated surface before coating. The primer liquid only need to brush a thin layer, the surface is not sticky rear can be coated with sealant. (the company is supporting the various primer supply)

Requirements of polysulfide sealant waterproof construction safety. The non sagging type and self leveling, high elongation, low modulus of two-component polysulfide sealant for fully cured rubber like elastic body. With high ratio of main agent (A): curing agent (B) =100:10 (quality, standard condition), with the seasons. Change of regional temperature. The available amount of curing agent used to adjust for the length range of B components in 10-14. The high temperature in summer, when construction of a two-component polysulfide sealant for building on the solidification time is faster, the winter construction,Low temperature solidification is slightly slower, in the north of two-component polysulfide sealant for building life up to 140 years in the south, up to 98 years. In the factory, our company has been in accordance with the quality ratio is good, and in the box with a plastic tube into the open, users need not worry about the proportion of the mass ratio when in use, only need to open the packaging of A components and B components together evenly, can be used.
