Product Description
One component polyurethane waterproof coating is prepared by the reaction of special polyether and isocyanate to form prepolymer, with a variety of additives. It does not contain crosslinking and
curing agent, and it is completely cured by
absorbing water in the air. This kind of coating is a kind of wet curing coating, which has the characteristics of high strength, high elongation and good water resistance. It forms a tough
seamless film on the surface of the base,
and has strong adaptability to the deformation of the base.
Characteristics
1. It does not contain coal tar, asphalt and benzene organic solvents, which is environmentally safe.
2. The construction operation is convenient and safe, and the disadvantages of uneven mixing of two-component
materials affecting the use effect are overcome.
3. It has good acid resistance, alkali resistance, heat resistance, cold resistance and aging resistance.
4. The coating is compact, tough and elastic with good integrity.
5. Strong adhesive force, able to bond with concrete, wood, glass, metal, rubber and other different materials.
It is widely used in roof, underground, toilet room, tunnel, road and bridge, culvert, pool and other waterproof and
anti-seepage works.
Construction Method:
Spraying method, scraping method
1. Base surface treatment: the base surface shall be solid, flat, dry, free of sanding and oil pollution, and the low
concave and damaged parts shall be filled and trowelled. Before construction, the dust, sand, mortar, hard block
and other sundries on the surface shall be cleaned. Roof water outlets, air vents, equipment and facilities, sanitary
facilities, etc. shall be installed firmly in advance, with tight and flat joints.
2. Construction of additional layer: the weak parts such as internal and external corners and through wall pipes shall
be reinforced with additional layer. It can be made into "one cloth and two coatings", in which the carcass reinforcement material should preferably be polyester non-woven. During the construction, it is necessary to brush
the coating once, then immediately lay the matrix reinforcement material, and then brush the coating on the surface.
3. Large area painting: the evenly mixed paint shall be evenly painted on the base surface with rubber scraper or metal scraper, and the thickness of the coating shall be 1.5mm-2.0mm, which shall be scratched in 3-4 times. The
direction of the later one shall be perpendicular to the direction of the previous one. The next coating construction
can be carried out after the previous one is cured, and the interval of each time shall be 24h (the low-temperature
construction time shall be extended accordingly).
4. Construction of protective layer: If tiles and other procedures need to be applied outside the waterproof layer, it is
recommended to perform sanding treatment before the last coat is applied to avoid tile adhesion;for the painted
waterproof layer, protective measures shall be taken in time, and construction of protective isolation layer shall be
carried out according to relevant specifications or design requirements.
Notes:
1. When the coating is not fully cured, it is strictly prohibited to get on or carry out the next construction.
2. Construction is strictly prohibited in rainy days, and contact with rainwater is strictly prohibited before film curing.
3. The construction temperature should be 5-35 ºC.
4. There is no need to add diluent when scraping. If you need to add diluent, please consult relevant technical
personnel.
5. Reference dosage: 1.0mm thick coating, the total dosage of coating is about 1.5-1.7kg/.
6. It is not recommended to directly use polyurethane coatings and water-based coatings or coils to avoid reactions
affecting the waterproof layer.
7. It should be ready to use after opening the lid to avoid thickening or skinning.
