Paint peeling 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 put on, putty, brushed with primer and repainted. Exfoliation over a large area must scrape all the paint off and repaint it. 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. Cracked 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. 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. Stain 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. 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. Tarnished 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.
