During construction, some problems will happen, which will affect the progress and quality of construction. The emergence of these problems will lead to a decline in the quality of epoxy floor. There are eight kinds of common problems in the construction of epoxy floor, which will affect the construction effect. These eight kinds of construction hard injury are generally caused by improper construction, we only need to pay attention to the construction process, as far as possible in accordance with the requirements of construction, we can effectively avoid these problems. Analysis of eight major injuries in epoxy floor construction
First, the paint surface is rough.
The surface of the new paint is rough, usually because the brush used does not clean the epoxy paint or is caused by environmental pollution. It is also possible that the paint is mixed with the paint skin, not precipitated and filtered before use, or the paint is not dry when stained with dust. In order to prevent the above problems, we must use clean paints and paint barrels. Before using the old lacquer, filter paper or clean nylon stockings must be used. In addition, the painted surface should be covered with a cover or cardboard when the paint is dry. If the paint surface is rough, after it has dried thoroughly, use dry-wet sandpaper to polish it smooth and clean, and then re-brush the paint. Pay special attention to the fact that the paintbrush must be clean.
Two. Paint bubbles
First of all, use a sharp object to puncture the bubbles, if there is water, that is, under the paint layer or behind the moisture infiltration, sunlight, water vapor, will be the top of the paint bubble. At this point, first with a hot air gun to remove the foaming paint, let the wood naturally dry, then brush the primer, and finally re-paint the entire repair surface. If there is no water in the bubble, it may be wood cracking, there is a small amount of air in the sun, the air expansion, paint skin bulging. Faced with this situation, first scrape off the foaming paint skin, then fill the cracks with resin filler, re-paint, or no filler, after scraping the paint skin, directly coated with microporous paint.
Three. Varnish without luster.
Direct varnishing without primer or primer or inner coating before drying can lead to a lack of gloss. Secondly, poor quality of gloss paint is also a reason. The solution is to use dry-wet sandpaper to rub off the old paint, brush away the grinding dust, wipe the surface with a clean wet cloth, and then re-paint after drying. It is also important to pay special attention to the fact that the paint may lose its luster when the film is dried when the temperature is very low.
Four. Paint stains. 油漆表面产生污斑的原因很多。比如墙上的物质被乳胶漆中的水分溶化而锈出漆面形成污斑，用钢丝绒擦过的墙面会产生锈斑，墙内暗管渗漏也会出现污斑等等。为了防止出现污斑，可先刷一层含铝粉的底漆，若已出现污斑，可以先除去污斑处的乳胶漆，刷层含铝粉的底漆后，再重新上漆。
There are many reasons for stains on the surface of paint. For example, the material on the wall is dissolved by water in the latex paint and rusted out of the paint surface to form stains, wiped with steel wool wall surface will produce rust spots, wall hidden pipe leakage will also appear stains and so on. In order to prevent stains, can first brush a layer of primer containing aluminum powder, if there is stains, you can first remove the stains of the emulsion paint, brush the primer containing aluminum powder, and then re-paint.
Five. Paint peeling off
It may be that the surface of the object is too smooth. If the original paint is varnish or powder (with untreated paste paint), the new paint on the surface will not stick well. Or it may be wood decay or metallic rust, and also because of poor paint quality. A small area of paint peeling, can be first sanded with fine sand paper, then put on putty, brush the primer, and then re-paint. The large area must be scraped and repainted.
Six. Sticky little animals on the surface.
Often encountered such a situation, just painted things are easy to stick to insects, mosquitoes and other small animals, this time to remove them as soon as possible, because the paint has not yet dried, it is easier to repair, as long as the brush dipped a little paint can be restored. If the paint is almost dry, wait until the film is completely stiffened and the bugs are wiped off so that the smooth surface doesn't mess up.
Seven. Cracks on paint surface
This situation is also relatively common, it is easier to deal with, if the floor coating crack area is relatively large, most of us are using chemical paint remover or hot air gun to remove the crack area, and then re-paint. If the crack area is not very large, then use sand grinding block or wet-dry sandpaper dipped in a little water, grinding the broken paint, slowly grinding smooth, put on putty, then brush the primer, re-paint.
Eight. Paint did not dry after a long time.
Paint does not dry, it must be related to indoor ventilation or temperature, poor ventilation or low temperature will make the paint dry slowly. So what you have to do is open some doors and windows to promote ventilation, or you can put a heater indoors to increase the indoor temperature. If the problem can not be solved, it may be that the surface of the paint is too greasy. At this point, you can remove the paint with the above chemical paint remover or heating method, wipe the surface thoroughly, and then re-paint.
