In view of the above three, if you want to achieve the top coat without blistering, you should:
1.
Choose a mixing equipment that produces less mechanical bubbles.
After mixing, let it stand and defoam for 3-5 minutes before applying to reduce the amount of air entering
.
2.
Reduce or eliminate microbubbles by adjusting the coating formula
.
Specifically, the foam problem can be significantly reduced by selecting low-foaming raw materials or adjusting the optimal viscosity
.
3.
After each coating trowel before making the surface layer or after coating, check whether there are bubbles on the surface.
If there are bubbles, use a defoaming roller to roll back and forth on the floor to deflate the bubbles.
Be careful, and there can be no omissions, and it is true that the next process can be carried out after the coating is cured
