How to distinguish the advantages and disadvantages of polyurea waterproof coatings

1, query security code: query security code is the most direct and effective identification method. For well-known brands of waterproof coatings, there is a product authenticity inquiry system in official website. The authenticity query code cannot be imitated, and can only be queried once. In addition, you can also communicate with official website customer service and inquire by SMS.

2. Check the outer packaging: Usually, well-known brand products have certain requirements for product packaging. Exquisite packaging not only represents the corporate image, but also promotes the products to some extent. The waterproof coating of genuine packaging is bright in color, clear and unambiguous in handwriting, and the specifications are marked with production date, service life, name and place of origin.

3. Odor discrimination: The waterproof performance of two-component cement-based waterproof slurry on the market is more stable than that of single component. Secondly, the liquid material in high-quality waterproof slurry has a faint smell, while the inferior waterproof coating will have a strong and pungent smell.

Precautions before construction of polyurea waterproof coating:

1. Before polyurea construction, ensure that the base temperature is 3℃ higher than the dew point temperature, and keep continuous stirring during construction.

2. If the polyurea coating is found to have defects such as blistering and spray leakage during inspection, it needs to be repaired immediately.

3. If a defective part is found within a short time (≤6h) after spraying, the surface of the defective coating can be polished, and polyurea can be directly sprayed again after cleaning.

4. If the defective parts are found for a long time (> 6h) before spraying, the surface of the defective coating (extending outward to 5 ~ 10 cm) should be polished clean, then coated with special treatment agent, and then sprayed with polyurea waterproof coating with special repair equipment for repair and leveling, so as to make the whole coating continuous, dense and uniform.
