Shanxi fire retardant coating substrate care is very important, for example, brush the wall, if the wall not only has dust and some impurities on it, without cleaning directly paint, the result is uneven brush, also not smooth, and the color than the original color of paint to darker, the most important thing is that the service life is not long, will soon peel off. Therefore, the treatment of the substrate is very important. Here, Shanxi fireproof coating manufacturers introduce how to deal with the substrate of fireproof coating.

1, we should be clear that all the impurities on the surface will affect the construction of the coating, but also affect the performance of the fire retardant coating. The presence of impurities not only affects the appearance of the coating film, but also causes the coating film to fall off in severe cases. Therefore, the substrate must be cleaned before construction. If it is ordinary dust, it is good to wipe it quickly. If it is rust, a shovel can be used to remove peeling and falling antirust paint, and then a steel wire brush can be used to remove rust. Ensure that the substrate is clean.

2. After the construction of fire retardant coating is completed, we should maintain its exterior coating to achieve the surface finish required for fire retardant coating engineering construction, so that there is a good adhesion foundation when painting.
