Construction Points waterproof coating waterproof material polyurethane continuous research and testing, the final polymer cement waterproof material works well, it is also relatively easy construction, it remains a very long time, usually do not have any in 20 years Problem acrylic polyurethane finish, concrete construction essentials I am here to everyone. 1. Should be at least 5 ℃ temperature conditions of construction, not construction precipitation is expected within 24h. 2. Brushing should anyway cross, the interval for 4h. 3. If you have special requirements for coating, brushing the surface layer may consider increasing the number of passes. 4. Construction, particularly polyurethane what humidity is low temperature polyurethane adhesive, the drying time should be extended. 5. Construction sites such as higher temperatures may be appropriate to increase the amount of water when mixing, in order to reduce the viscosity of the construction. Waterproof coating nanotechnology penetrating protectant product is natural, inorganic silicate, active silica, special catalysts and other functional additives formulated through nanotechnology, a new generation of water-based, environmentally friendly, crack waterproofing agent . After using the base surface to form a transparent waterproof and breathable invisible layer of protection when the drops fall on the surfaces of buildings, like the lotus leaf falls on the same, leaving no trace.
