problem 1. Stick bugs on the paint:

try to remove the bugs before the paint is dry, and then touch up the surface with a little oil with a brush. If the paint has begun to dry, wait until the paint film is completely hardened, and then wipe the bugs off, so as not to make a mess of the surface

problem 2: the paint does not dry:

if the indoor ventilation is poor or the temperature is too low, the paint will dry slowly. It is possible to open all doors and windows to promote ventilation, or put a heater indoors to increase room temperature. If the problem is still not solved, the painted surface may be greasy. Chemical paint remover or heating method can be used to remove the paint, wipe the surface thoroughly, and then repaint

problem 3. Dark spots appear on the surface of painted wood:

it may be caused by the fact that the knots are not sealed before painting, and the resin seeps out of the knots when they are heated by the sun. At this time, the paint can be scraped off with a scraper, and then polished with fine sandpaper until the knots are exposed. Seal the knots with sealing paint, and repaint after it is completely dry

problem 4. Rough paint surface:

the newly painted surface is rough, usually because the paint brush used is not clean or polluted by the surrounding environment. It may also be that the paint is mixed with paint skin, which has not been precipitated and filtered before use, or the paint is stained with dust when it is not dry. In order to prevent the above problems, clean paint brushes and barrels must be used. Before using the old paint, be sure to filter it with paint filter paper or clean nylon stockings. In addition, the painted surface should be covered with a cover or cardboard before the paint is dry to prevent dust. If the paint surface is rough, after it is completely dry, polish it with dry and wet sandpaper, wipe it clean, and then brush the paint again. Pay special attention that the paint brush must be clean

problem 5. Wrinkle of paint film:

it is usually caused by brushing the second time before the first paint is dry. At this time, the solvent in the lower paint will affect the upper paint film and wrinkle it. In this case, chemical mercury remover or heating method can be used to remove the wrinkled paint film and repaint. Remember, you must wait until the first coat of paint dries out before you apply it again

problem 6. Loss of 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. Grind off the old paint with dry and wet sandpaper, brush off the grinding dust, wipe the surface with a clean wet cloth, and brush the top paint again after it is completely dry. Special attention should be paid to that when painting in a low temperature environment, the paint film may also lose luster after drying

problem 7. Mildew and discoloration:

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

problem 8. 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 out of the paint surface, the wall surface wiped with steel wool will produce rust spots, and the hidden pipe leakage in the wall will produce stains, etc. 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

problem 9. 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

problem 10. Paint peeling:

it may be because 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

problem Xi. Cracks:

in this case, it is mostly necessary to remove the paint with chemical paint remover or hot-air gun, and then repaint. If the fracture range is not large, then you can use sanding block or dry and wet sandpaper to rub off the broken paint. After the surface is polished smooth, apply putty, brush primer, and repaint

problem 12. Blistering of paint:

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 into bubbles. At this time, first remove the blistering paint with a hot-air gun, let the 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. 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
