First, there is a crack
In most cases, the paint must be removed with a chemical paint remover or a hot air gun and then repainted. If the fracture range is not large, then sanding blocks or wet or dry sandpaper can be used to dilute the broken paint. After the surface has been smoothed, apply putty, apply a primer, and repaint it.
Second, the paint flow
Once the paint is too thick, it will cause runny. The paint can not be dry yet. Brush it with a brush. If the paint has started to dry, dry it. Use a fine sandpaper to smooth the paint, clean the surface, clean it with a damp cloth, and re-apply it. Outer paint, be careful not to brush too thick.
Third, paint peeling off
It may be because the surface is too smooth. If the original paint is lacquer or powder (with untreated sizing paint), the new paint will not stick to the surface. Or it may be wood decay or metal rust, or peeling off due to poor paint quality. A small area of ​​paint is peeling off. It can be sanded with fine sandpaper, then putty put on it, brushed with a primer and repainted. Exfoliation over a large area must scrape all the paint off and repaint it.
Four, paint foaming
First of all, the puncture is broken. If there is water coming out, it means that under the lacquer layer there is moisture infiltration underneath or behind it. After the sun shines and the water evaporates into vapor, the paint is lifted up into foam. At this point, the blistering paint is removed with a hot air gun, the wood is allowed to dry naturally, then the primer is applied, and finally the entire repair surface is repainted. If there is no water in the bubble, it may be cracked wood grain, there is a small amount of air, the sun through the sun, the air expands, the paint bulge. Faced with this situation, first scrape off the blistering paint, then use a resin filler to fill the cracks, repaint it, or use no filler. After the paint is peeled off, apply a microporous paint directly.
Fifth, lose luster
The reason is that the primer is not applied, or the primer and the inner layer of the paint are not dry, and the light paint is directly applied. As a result, the light paint is absorbed by the wood and loses luster. The poor quality of glossy paint is also a reason. Grind the old paint with wet or dry sandpaper, brush the dust, wipe the surface with a clean, damp cloth, and dry the paint again. It is important to pay attention to the fact that paint is applied in very low temperatures and the paint film may lose its luster after it has dried.
Six, film wrinkling
It is usually caused by the second pass of the first pass of the paint. At this time, the solvent in the lower layer paint will affect the upper layer of the film to make it wrinkle. In this case, the wrinkled paint film can be removed by chemical amalgamation or heating and repainted. Remember, we must wait until the first time after the paint is dry before we can go on the second pass.
Seven, paint rough
The newly painted surface is rough, usually the paint brush used is not clean or contaminated by the surrounding environment. It is also possible that the paint is mixed with patent leather, which has not been precipitated and filtered before use, or has been dusted when the paint is dry. In order to prevent these problems from occurring, clean paint brushes and paint buckets 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 when the paint is dry to prevent dusting. If the paint is rough, after it has dried, use a wet or dry sandpaper to polish it and clean it, then repaint it. Pay special attention to the paint brush must be clean.
Eight, paint is not dry
Indoor ventilation is not good 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 it still fails to solve the problem, it may be that the painted surface is greasy. This can be removed with a chemical paint remover or a heating method, thoroughly rubbing the surface, and then repainting.
Nine, lacquer stick on the insect
Try to remove the insects when the paint is dry, and then use a brush to lightly repair the surface. If the paint has started to dry out, wait for the paint film to harden completely, and then wipe off the bug. This will not mess the surface.
X. Dark spots on the surface of varnished wood
It may be that the wooden section was not sealed before being painted. After the sun was exposed to the sun, the wood section was heated and the resin leaked from the knot. At this point scraper can be used to scrape off the paint, and then polished with fine sandpaper to expose the knots, seal the knot with a knotted paint, and wait until dry, and then re-paint.
Eleven, stains
There are many causes of stain on the paint surface. For example, the moisture in the latex paint dissolves the substance on the wall and the paint surface is rusted. The wall surface that is rubbed with the steel wool will cause rust spots, and the dark pipe inside the wall will appear with stains. In order to prevent stains, a layer of primer containing aluminum powder may be applied first. If stains are present, remove the emulsion paint at the stains first, brush the primer layer containing aluminum powder, and then re-paint.
Twelve, moldy discoloration
This problem occurs most often on wet paint surfaces, such as when water vapour condenses on glass or metal surfaces. At this point can be used fungicides, according to the instructions of the instructions to deal with moldy parts, to be killed after the mold, the surface clean and then re-paint.
