Does the lack of film thickness of epoxy floor paint cause cracks? To this end, the epoxy floor paint manufacturer said that the answer is yes. If the film thickness of epoxy floor paint is not enough, pinholes, flying paint, improper drying, improper curing, etc., will lead to cracks in epoxy floor paint. Two kinds of epoxy floor paint are damaged due to improper film thickness. One is that the paint is too thick, the other is that the film is too thin. If the film is too thick, the drying of the volatile paint film is not good. The residual solvent in the film is close to the base material, and the lower layer is soft. It is easy to cause foaming of the coating and bonding with the base material is not strong. However, if the thick coating is not firm to the base material, scratch corrosion will occur quickly.
For catalytic or internal curing epoxy floor paint, internal shrinkage will occur, causing cracking or even peeling of epoxy floor paint. The coating is too thin, usually resulting from too little paint on the surface due to rapid construction. The damage of epoxy floor paint in these areas mainly starts from pitting corrosion. As the dots gradually expand, scratch corrosion occurs in the thinnest area of the coated surface. This is a common damage of epoxy floor paint. As long as the builder works carefully, he can do a good job.
