Solution to the problem of interior decoration pai

Paint is often one of the essential materials in interior decoration. Painting is a very important link, which affects the style effect of the overall environment. But paint is very knowledgeable, especially the environmental protection issues that everyone is concerned about, as well as paint peeling, blistering, cracks and other issues, which makes inexperienced consumers who know nothing about paint helpless! In addition, I don't know how to remedy the serious problems such as dirt and cracks in the paint. The following is a detailed description of the specific phenomenon of paint problems, and “ Suit the remedy to the case and provide the most satisfactory solution for you

1. Foaming

first, puncture the bubble. If water emerges, it means that there is moisture infiltration under or behind the paint layer. Once exposed to the sun, the water evaporates into steam, which will top the paint skin into bubbles. At this time, first remove the blistering paint with a hot-air gun, let the base wood dry naturally, then brush the primer, and finally re paint 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. Once 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

2. 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 range is not large, then you can use sandpaper or dry and wet sandpaper to rub off the broken paint. After the surface is polished smooth, apply putty, brush primer, and repaint

paint peeling is a common phenomenon. The reason is that the surface is too smooth. If the original paint is glossy 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. If the paint peels off in a small area, it can be polished with fine sandpaper, then puttying, priming and repainting. The paint must be scraped off and repainted for large areas of peeling

4. Mildew and discoloration

this problem often occurs on wet paint surfaces. For example, water vapor condenses on glass or 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

5. Paint flowing

painting too thick at one time 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 fine sandpaper, 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

6. No gloss

the reason is that the gloss paint is directly applied without primer, or the primer and inner paint are not dry. As a result, the gloss paint is absorbed by wood and loses gloss. The poor quality of gloss paint is also a reason
