Cementitious capillary crystalline waterproofing material that waterproof coating waterproof material from Portland cement, quartz sand, a variety of active chemical substances and other components. With strong penetration of water to achieve the effect of a chemical reaction and water leak. Two-component polyurethane waterproof coating is a two-component polyurethane waterproof coating a variety of additives mixed antioxidant, curing agent, catalyst, etc. A polyurethane prepolymer component and a diisocyanate containing the reaction from the B group, according to a certain proportion with the formation of the overall after solidification and flexible two-component polymer waterproof coating waterproof material continuous research and testing, the final polymer cement waterproof material works well, construction is also more convenient, it's time to keep it long, usually do not have any problems of color polyurethane waterproof coating in about 20 years, the specific construction essentials I am here to everyone. 1. Should be at least 5 ℃ temperature conditions of construction polyurethane waterproof coating, the expected rainfall, not construction 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 polyurethane waterproof coating amount of air humidity is particularly large, low temperatures, 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.
