You will find that some epoxy flooring is very strong, and some epoxy flooring paint is easy to break, of course, there are many reasons. Nowadays, everyone on the market can make floor paint, professional and unprofessional, mixed with fish and dragon, so the same thing has made different qualities. Today, we will popularize the reasons for the large area of skin damage of epoxy floor paint: poor surface treatment before painting, oil stain, wax, vapor, and water vapor on the surface of the coated objects. Dust and chemicals. Or if the interval between surface pretreatment and painting travelers is too long, the surface of the coated object should be treated and cleaned, and the painting construction should be carried out immediately. Inappropriate choice of primer. If the hardness of primer is too high. If the surface of the coating is too smooth, the primer with good adhesion and wettability should be chosen.
1. The fault of the builder or the lack of experience of the builder
1. The surface treatment before painting is not very good. There are oil, wax, water vapor, dust and chemicals on the surface of the coating, or the interval between surface pretreatment and painting construction is too long.
2. Excessive smoothness on the surface of the coated material, without specific treatment or selection of specific primer materials.
3. Before the primer is dry enough, the coat or varnish is liable to crack or fall off.
4. Coating film is too thick, because the surface has dried through, while the bottom dried slowly or not thoroughly, during the drying process, cracking and peeling are caused by excessive shrinkage of topcoat.
5. The high temperature of the construction environment, the large painting distance (spraying) and the fast volatilization of diluent cause the floor paint film not to be leveled, which makes the paint film appear wrinkle orange peel phenomenon. In order to speed up the drying of the coating, too much drying agent will cause wrinkling of the epoxy floor paint. Avoiding construction at high temperature, or strengthening ventilation, reducing construction environment temperature, adjusting spray distance, properly adding slow-drying solvent and reducing the amount of drier are the methods to avoid and overcome the wrinkling of floor paint film.
