If the adhesion of epoxy floor paint is not enough, there will be a drop phenomenon, which seriously affects the aesthetic and practical performance of epoxy floor paint. In fact, the so-called epoxy floor paint is applied to the concrete base, forming a thin film. This coating has the functions of decoration, wear resistance, compression resistance, dust-free and easy cleaning. But in order to maintain and use these functions better, the bond between epoxy floor paint and concrete should be guaranteed first, so that there will be no shedding phenomenon. Therefore, if we want to give full play to the good function of epoxy flooring, we must strictly control the bonding performance between the two. It can be seen that the bonding force of epoxy floor paint is particularly important, but in the actual construction, it will be found that it is not easy to ensure the bonding force of epoxy floor paint. Because it is influenced by many factors. Two factors have the greatest influence on the bonding ability of epoxy floor paint.
First, the concrete base condition.
Rough, dry and solid concrete base is a good carrier of epoxy floor paint.
1. Open the pore. As a kind of porous floor, the more open the inner capillary, the better the penetration of epoxy floor paint and the better the bonding force. Therefore, the old concrete floor must be thoroughly polished to make the pore of concrete fully open.
2. Low water content. The lower the moisture content of base concrete, the better the bonding force between base concrete and floor paint.
3. Hardness is better. The concrete floor is too loose, the epoxy floor paint and the base will lose the cohesive force, the loose layer should be removed before construction.
II. Epoxy Floor Paint
The quality of epoxy flooring and the rigorous and correct construction process are the basis to ensure the quality of the flooring.
1. Quality of floor paint. In order to choose high quality epoxy floor paint, the heat and temperature generated during curing will affect the adhesion between the floor paint and the base. Therefore, not only high quality epoxy floor paint, but also high quality curing agent should be selected.
2. Construction technology. Construction is one of the most important factors affecting the quality of the floor. Only by ensuring the correct and rigorous construction can the adhesion between the floor paint and the base be guaranteed and the high quality epoxy floor be built.
What are the factors affecting the bonding strength of epoxy floor paint? How to prevent it?
These are the most important factors affecting the bonding force between epoxy floor paint and base. In the construction of epoxy floor paint, we should focus on these two aspects. To minimize the possibility of building high-quality epoxy flooring.
