In short, the primary purpose of ground treatment before floor painting is to remove surface dirt, enhance the adhesion of the floor paint coating to the ground, extend the service life of the coating, and fully exert the protective effect of the coating. Only in the treatment of clean, flat ground construction can a smooth, flat, beautiful floor paint coating be applied to ensure good decorative coating.
2. The floor treatment before the floor paint is applied is to create a suitable surface roughness and improve the adhesion of the floor paint coating. Floor paint coating is adhesion on the ground, relying on the interaction between the polar genes in the coating and the ground molecules, and machinery
Engagement. After ground sanding and sandblasting, the surface becomes rough and the surface area increases significantly, which increases the contact area of ​​the floor paint coating with the ground and the mechanical engagement and improves the adhesion of the coating.
3. The treatment of the floor paint before the construction of the floor paint is to increase the compatibility of the floor paint coating and the bottom layer. In the maintenance work, the treatment of the coating of the old floor paint is involved. It is determined whether or not to remove all the floor paint according to the specific conditions. Reservations. If the coating is applied to a protective floor paint and the coatings for new and old floor coatings are properly matched, it may be considered to retain the old floor coating without failure, which can further increase the overall protection capability of the floor coating. If it is a floor painting application with the main purpose of decorating, the floor coating shall be completely removed. Or after the old paint on the floor paint is polished, the paint is leveled and the putty is closed to ensure the flatness of the substrate.
1. The ground treatment before the floor paint is applied to ensure and improve the decorative and protective performance of the floor paint coating. When the oil and water are present on the surface of the floor, the compatibility of the oil and water with the floor paint coating is extremely important. Poor, it is difficult to complete the floor paint coating, even if it can form a complete coating, due to ground dirt, will greatly reduce the adhesion of the floor paint coating and easy to fall off. When dust or sand is not completely removed on the ground, it will cause pitting on the floor paint coating, which will seriously affect the appearance of the floor paint coating. When the ground is uneven, pits, pores, etc., it will affect the appearance of the floor paint coating quality, the situation is serious, it is recommended not to construction.
