Its property belongs to organic and inorganic composite waterproof coating. This coating not only has the extensibility, waterproof and elasticity of polymer film, but also has the advantages of high strength of cement hydraulic materials and easy bonding with wet base. It can adjust flexibility and strength according to the design requirements of different projects or different project parts. The construction method is flexible and convenient, and water is used as dispersant, It overcomes the common diseases that tar, asphalt and solvent coatings are easy to pollute the environment, which is conducive to environmental protection

Product features

1) It can be constructed on the wet or dry base course without flowing on the facade.

2) The coating has high toughness, water resistance, weather resistance and excellent durability.

3) Simple construction and short construction period.

4) The coating has air permeability, and the waterproof layer will not bulge even if the base course is wet.

5) The color can be added to the coating according to customer preferences.

Scope of application

1) It is suitable for waterproof, anti-seepage and moisture-proof works of non exposed roof, toilet and bathroom and external wall.

2) It can also be used for coating waterproofing of underground works, tunnels and caverns.

3) Road and bridge, pool, water conservancy project, coating waterproof project.

Base course - the surface of the base course shall be flat, solid, free of sharp corners, floating dust and open water, and the waterproof joints shall be treated according to the design requirements. The oil stain shall be removed, and the concave damaged part shall be leveled.

Proportioning - proportioning shall be carried out according to the proportion of liquid material, powder material and water marked on the product package. The filling amount of water can be adjusted appropriately to adjust the viscosity of the coating and meet the construction requirements of different parts of the facade and plane.

The mixing method of polymer cement waterproof coating is to pour the liquid material and water into the mixing bucket first, slowly add the powder under the continuous mixing of the portable mixer, stir for at least 5 minutes, and thoroughly stir evenly without agglomeration in the form of slurry.

Additional waterproof layer for details - fill the reserved groove with sealing material according to the design requirements, apply jsa-101 to the internal and external corners, pipe roots and other details for multiple times (2-4 times), and lay a layer of matrix reinforcement for underground works.

Construction of large surface waterproof layer - the waterproof film shall be coated several times, preferably at least four times. The coating time of each time is generally 8h, which should be extended in winter. The thickness of each coating should be 0.4-0.5mm, and the amount of coating should be about 8kg / ㎡. It is not suitable to be too thick. The facade construction should not add water or less water, so as to prevent the coating from flowing, so that the facade thickness is not easy to reach the design thickness, and at the same time, the accumulated materials at the internal and external corners are too thick, resulting in cracks. When adding matrix reinforcement materials, the matrix shall be paved without wrinkles, and the overlapping shall not be less than 100mm. During construction, the coating shall be applied first, and then the coating shall be applied again.

After the completion and acceptance of the coated waterproof layer, the protective layer shall be constructed according to the design requirements.
