Epoxy floor is a kind of floor with high strength, wear resistance and beautiful appearance. It has the advantages of seamless and solid texture. During the construction of epoxy floor, some problems often occur, which affect the construction effect. For these common construction problems, the construction effect of epoxy floor will be reduced directly. There are eight common problems in the construction of epoxy flooring, which will have a big or small impact on the construction effect. How should we carry out construction to avoid these problems?
The newly painted surface is rough, usually because the brush used does not clean epoxy paint or is caused by environmental pollution. It may also be that the paint is mixed with paint, which has not been precipitated and filtered before use, or is covered with dust when the paint is not dry. To prevent these problems, clean brushes and buckets must be used. Before using the old paint, it must be filtered with filter paper or clean nylon stockings. In addition, the painted surface should be covered with a cover or cardboard when the paint is not dry to prevent dust. If the surface of the paint is rough, after it is dried out, polish it with dry and wet sandpaper, then brush it again. Special attention should be paid to the fact that the paint brushes must be clean.
First, puncture the bubbles with sharp objects. If water comes out, it means that there is moisture under or behind the paint layer. When the water evaporates into vapor after sunshine, it will bubbles the top of the paint. At this time, first remove the foaming paint with hot air spray gun, let the wood dry naturally, then brush the primer, and finally re-paint the entire repair surface. If there is no water in the bubbles, it may be wood grain cracking, with a small amount of air in it. When the sun shines, the air expands and the paint bulges. Faced with this situation, first scrape off the foaming paint, then fill the cracks with resin filler, re-paint, or no filler, after scraping off the paint, directly coat with micro-porous paint.
Painted but not glossy
The absence of primer or primer and direct varnish before the inner paint is dry can lead to a lack of luster. Secondly, the poor quality of varnish is also a reason. The solution is to use wet and dry sandpaper to rub off the old paint, brush off the polished dust, wipe off the surface with a clean wet cloth, and then brush the paint again after drying out. It is also important to pay special attention to the fact that the film may lose its luster after drying when it is painted in a very low temperature environment.
