Waterborne epoxy floor paint has a relatively good hardness. Compared with ordinary epoxy, it is harder from east to west, relatively brittle, has pressure drop, and is easy to break. Therefore, from the foundation treatment, the requirements for the foundation are higher than traditional epoxy. .
First, the concrete should be polished carefully, so you can't miss any areas that are not polished, especially many areas with poor strength. Be sure to sand to areas with strength.

At the same time, it is recommended that the sanding be performed in two passes, twice in a cross shape to prevent leaks and to make the sanding more thorough.
Second, it is recommended to use a vacuum cleaner after cleaning after cleaning, so that the coating can penetrate better, the tension of the water is large, and it is easy to affect the permeability;
Third, for the floor without expansion joints, deep-seam joints should be performed to prevent irregular cracks due to the internal stress of concrete in the future. Where there are expansion joints, the joints should be used to clean the joints, and then use a vacuum cleaner to vacuum.
