Sometimes after epoxy floor paint has been laid for a period of time, it will be found that the problem of foaming appeared on the floor, which is very annoying. The main cause of floor blistering is that the base is not completely closed or not eliminated before the construction of the surface layer and the leakage of ventilation. Once it is found that we need to deal with it in time, then how should we prevent the foaming of epoxy floor paint? With the above foaming methods of epoxy floor paint, we must have a deeper understanding of the foaming of epoxy floor paint. Therefore, whether in the early construction of epoxy flooring, or the selection of raw materials, or even later maintenance, we should pay attention to the phenomenon of foaming stifled in the cradle.
Foaming Treatment of Epoxy Floor
1. Do a good job of waterproof layer on the base
To prevent water vapor from penetrating upward and control the base or waterproof layer, the water content should be low. The compressive strength of the base or waterproof layer is greater than 20 Mpa, so the epoxy construction should be carried out.
2. Strengthen the inspection and treatment of grass-roots level
After scraping each coating before the surface layer, check once whether there are bubbles on the surface, and some areas are bamboo broom flat brush, to deflate bubbles, we must carefully check, no omissions, make sure that no mistake to be cured after the next process.
3. Improving the cohesion between epoxy flooring and waterproofing layer
By improving the cohesion of epoxy flooring layer and waterproof layer, we can overcome the initial blister account and avoid the occurrence of blisters on the flooring.
4. Prevention of Foaming in Floor Construction
The bottom layer should choose good quality materials, so that part of the permeation into the grass-roots or waterproof layer, forming a whole. It can also improve the bonding ability and prevent residual substances.
5. Foaming prevention after floor construction
After the construction of epoxy floor, do not let the sun shine directly, you can check the temperature difference between the surface and inside of the epoxy layer.
6. Clean up the base or waterproof layer
There should be no gap between the epoxy flooring or the grass-roots after the construction.
