Paint is an important part of interior decoration, which is prone to some thorny problems and makes people helpless. In fact, as long as you find out the cause of the problem and apply the right medicine to the case, it is not difficult to have satisfactory results. The following is about the problems that are easy to occur in paint. Beijing Huilongguan decoration company (Jinsheng Decoration) puts forward solutions to them, so that you can be handy in interior decoration

paint peeling: it may be because the surface is too smooth. If the original paint is gloss paint or powdery (add untreated color paste paint), the new paint will not stick firmly on the surface. Or it may be wood decay, metal rust, or peeling due to poor paint quality. Tips of Beijing Huilongguan decoration company: if the paint peels off in a small area, you can polish it with spinning paper, then apply putty, brush primer, and then repaint it. If a large area falls off, the paint must be stripped off and repainted

blistering of paint: first puncture the blister. If water emerges, it means that there is moisture infiltration under or behind the paint layer. Once exposed to the sun, the moisture evaporates into steam, which will top the paint into bubbles. At this time, first remove the starting paint with a hot-air gun, let the wood dry naturally, then brush with primer, and finally repaint the whole repaired surface. If there is no water in the bubble, it may be that the wood grain cracks and there is a small amount of air in it. As soon as it is exposed to the sun, the air expands and the paint skin bulges. In the face of this situation, first scrape off the blistering paint skin, then fill the cracks with resin filler, repaint, or without filler, directly apply microporous paint after scraping off the paint skin

cracks: in this case, it is mostly necessary to remove the paint with chemical paint remover or hot-air gun, and then re paint. If the fracture scope is not large, Beijing Huilongguan decoration company can use sanding block or dry and wet sandpaper to wipe off the broken paint. After the surface is polished smooth, apply putty, brush primer, and then paint again. Paint flowing: if the paint is brushed too thick at one time, it will cause flowing. Use a brush to open the paint before it is dry. If the paint has begun to dry, wait until it is completely dry, polish the paint surface with spinning paper, brush the surface clean, wipe it with a wet cloth, and then apply the outer paint again. Be careful not to brush it too thick

mildew and discoloration: this problem often occurs on wet paint surfaces. For example, water vapor condenses on glass and metal surfaces and often produces brownish black stains. At this time, you can use fungicide to treat the moldy parts according to the instructions of the manual. After the mold is killed, clean the surface, and then paint again

stains: there are many reasons for stains on the paint surface. For example, the water in the emulsion paint dissolves the materials on the wall and rusts the paint surface. The wall surface wiped with steel wool will produce rust spots. There are stains due to the leakage of concealed pipes in the wall. Beijing Huilongguan decoration company believes that in order to prevent stains, you can brush a layer of primer containing aluminum powder first. If there are stains, you can remove the emulsion paint at the stains first, brush a layer of primer containing aluminum powder, and then paint again

paint does not dry: if the indoor ventilation is poor or the temperature is too low, the paint will dry slowly. At this time, you can open all doors and windows to promote ventilation, or put a heater indoors to increase the room temperature. If you still can't solve the problem, Beijing Jinsheng Decoration 4006-338-883 may help you paint the surface greasy. At this time, chemical paint remover or heating can be used to remove the paint, and the surface can be completely wiped and repainted
