Paint is an important part of interior decoration, and it is easy to have some thorny problems that make people helpless. In fact, as long as you find out the real cause of the problem and have the right medicine, you will have satisfactory results. The following is the solution to the problems that are easily caused by paint, so that you can be more comfortable in interior decoration.

First, paint peeling may be due to the fact that 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.

Second, the paint blisters First, the bubble pierce, if water emerges, which means that the paint layer behind or behind the infiltration of moisture, the sun a sun, water evaporation into vapor, it will paint up into a bubble. 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.

Third, the occurrence of cracks This situation will most likely use chemical paint remover or hot air gun to remove the paint, and then re-painted. 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 is smoothed, apply putty, apply a primer, and repaint.

Fourth, stains on the surface of the paint caused by many reasons. For example, the water in the latex paint dissolves the material on the wall and the paint is rusted. The wall surface that is rubbed with the steel wool will cause rust spots, and the dark pipe inside the wall will be stained. To prevent blemishes, first apply a primer containing **. If stains are present, remove the latex paint from the stain, recoat the priming layer with ** and repaint it.

5. The cause of loss of luster is that no primer has been applied, or that the primer and the inner layer of paint have not been dried and there is a light paint on it. As a result, the light paint is absorbed by the wood and loses its luster. The poor quality of glossy paint is also a reason. Grind the old paint with wet or dry sandpaper, brush the dust, and clean the surface with a clean damp cloth. After drying, repaint the paint. 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.

6. Coarse paint The newly painted surface is rough, usually the paint brush used is not clean or polluted by the surrounding environment. It is also possible that the paint is mixed with patent leather. It is not precipitated and filtered before use, or it is 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.

Seventh, the paint does not work well indoor ventilation 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, the painted surface may be greasy. This can be removed with a chemical paint remover or heat, thoroughly rubbing the surface, and then repainting.

Eight, the paint surface glued to the bug as much as possible when the paint is not dry, remove the bug, and then use a brush to dip a little oil to 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.
