Paint wall decoration precautions perfect wall surface

1. The paint is foaming. First of all, the bubble is broken, if there is water, it means that there is moisture infiltration under the paint layer or behind the sun. After the sun shines, the water evaporates into steam, which will make the patent leather foam. At this point, the hot air spray gun is used to remove the foamed paint, the wood is naturally dried, 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 in the wood grain, and there is a small amount of air inside. After the sun shines, the air expands and the patent leather bulges. In the face of this situation, first scrape off the foamed patent leather, then fill the crack with the resin filler, repaint, or do not use the filler, after scraping off the patent leather, directly apply the microporous paint.

2. Cracks appear. In this case, it is mostly necessary to remove the paint with a chemical paint remover or a hot air spray gun before repainting. If the fracture range is not large, you can use sanding block or wet and dry sandpaper to wet the water, grind off the broken paint, after the surface is smoothed, put on the putty, brush the primer, and repaint.

3, the paint surface is rough. The newly painted surface is rough, usually because 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 that the paint is dusty when it is not dry. To prevent this from happening, a clean paint brush and paint bucket must be used. Always filter with paint filter paper or clean nylon stockings before using the old paint. In addition, the painted surface should be covered with a cover or cardboard when the paint is not dry to prevent dust. If the paint surface is rough, after it has dried out, smooth it with a dry and wet sandpaper, wipe it off, and then paint again. Pay special attention to the paint brush must be clean.

4, loss of luster. The reason is that the primer is not applied, or the primer and the inner layer paint are not dried, and the varnish is directly applied. As a result, the varnish is absorbed by the wood and loses its luster. The poor quality of varnish is also a cause. Use old wet and dry sandpaper to rub off the old paint, brush off the dust, wipe the surface with a clean damp cloth, and then dry it again. It is important to note that painting in a very low temperature environment may also result in loss of gloss after the film has dried.

5, the paint surface sticks to the bug. Try to remove the bugs when the paint is not dry, then use a brush to lightly polish the surface. If the paint has begun to dry out, wait until the paint film is completely hard and then wipe off the bug so that it does not make the surface messy.
