Engineering tiling / stones Foundation Waterproofing Membrane with High Tensile
911 Polyurethane Waterproof Coating is a type of waterproof material solidified in double component chemical reaction. Part A is polyurethane ester polymers, Part B is curing components, scrape on construction surface after stirring mixing A and B material according to certain proportion, it will form the overall elastic waterproof film after curing.
Product Features
1. The film with rubber elasticity, extensibility, high tensile strength.
2. Has good resistance to high temperature and low temperature flexibility.
3. Cover easily with thick slurry, coating no juncture and is strong.
4. Has certain corrosion resistance.
Scope of application
1. All kinds of roof and toilet waterproof engineering.
2. Applied to positive waterproof maintenance structure.
3. Basement, swimming pools, civil air defense projects, storage pool and other surface waterproof.

Construction Method
1. The construction surface need to be dry, solid, smooth and clean.
2. Mixing A and B material according to provided ratio, and fully mixing to be the black color.
3. This product coating is usually divided into two times, the coating thickness is 1.0 mm, it can construct the second time coating after the first time coating curing, The direction of the surface must be perpendicular to the first pass, The time interval shall prevail with non-stick hand.
Attention
1. Mixing materials should be finished within 20 minutes.
2. The construction temperature should be above 5 , construction environment need to keep the air circulation.
Shipping and packaging
1. Products should be sealed storage in ventilation, shady and cool place, close to the fire is prohibitedPrevent collisions during transport, valid for 12 months.
2. The packing is 30kg/set.
