When we park in the underground parking lot, we should also find that the ground of the car park is relatively smooth. And the gloss is pretty good. In fact, this is the use of epoxy flooring, epoxy flooring is not only used in the underground garage, but also in some sports venues, cafes and other large places. We usually find the construction team directly to carry out the construction, but during the construction, we may find such problems. For example, there will be some brush marks. The purpose of choosing epoxy floor is to have a glossy surface. So this problem can be said to be a fatal defect. What should we do in the construction process to avoid and solve this situation? Next we will give a detailed introduction.
Causes of brush marks:
A. Construction reasons: incorrect construction method, long construction time after mixing, even rolling brush, poor control of coating thickness.
B, tool reason: drum quality is not qualified, roller surface treatment is wrong.
C, paint itself: mainly due to poor levelling of paint and excessive viscosity of coatings. Thixotropic filler or auxiliaries.
A, pay attention to the construction method, and the curing time of the paint should not be too long. The two ends of the drum to the fillet, the thickness of the coating should not be less than 0.15mm as much as possible.
B, buy a little roller, use the tape to handle the roller surface before using the drum.
C. The causes of coatings, increase the leveling of coatings, reduce the viscosity of coatings, and minimize thixotropic fillers and additives. Particular attention should be paid to the phenomenon that leveling agents of wall coatings are used in floor coatings.
