>& gt;& gt; Lessons learned in paint

paint peeling

may be due to too smooth surface. 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

paint 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 moisture 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 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

cracks appear

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 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

paint flowing

painting too thick at one time will cause {hottag} 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

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

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

gloss loss

the reason is that the gloss paint is directly applied before the primer is applied, 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

wrinkle of paint film

is usually caused by brushing the second time before the first time of 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

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

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

the paint does not dry

the paint dries slowly if the indoor ventilation is poor or the temperature is too low. 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

stick bugs on the paint surface

try to remove the bugs before the paint is dry, and then use a brush with a little oil to gently repair the surface. 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
