1, construction
As a coating for DIY, it must have very good workability. The US market's waterproof coating gives the paint a leveling, thixotropic, and other easy-to-use performance depending on the use of the site and the construction method, enabling non-professionals to perform construction. . The United States one-component waterproof paint is also more because it has the advantages of direct construction and canning, and does not require the same mixing and stirring as the two-component coating.
2, resist cracks
Due to the large number of wooden structures in foreign dwellings, cracks are generated and changed more than concrete structures. Therefore, foreign paints pay great attention to the crack bridging performance of coatings. It is required that the coating film be resistant to crack deformation of at least 3 mm, and high-quality coatings can resist crack deformation exceeding 6 mm.
3, waterproof moisture
Waterproof, needless to say, is the basic function of waterproof coatings. Also, due to the fact that there are many wooden structures, if the air is wet, it will cause the construction to be moldy. Therefore, U.S. paint manufacturers designed moisture-proof coatings for parts that need to be in contact with water vapor, and their denseness not only prevents water, but also blocks the passage of water vapor, effectively preventing the occurrence of mildew.
Waterproof coatings are mainly divided into four categories: polymer emulsion waterproof coating, polymer cement waterproof coating, polymer cement waterproof slurry, and polyurethane waterproof coating. We can choose the suitable waterproof coating according to factors such as the characteristics of the house.
