What is the construction process of wall painting technology?

Painting project is one of the key projects of home decoration technology. If you want to get a generally satisfactory home improvement effect, don't let your guard down during construction! If problems are found in the construction, they should be considered immediately. The construction process of wall painting technology is that they will find more problems and spend more money. What is the specific construction process of wall painting? Let's have a look!

Construction process of mural painting: 1. Basic treatment. Before the wall coating is painted, the primer should be cleaned to remove impurities and dust in the primer. If the undercoat falls off or peels off, the skin must be removed from the original wall first. If there are cracks in the wall, please cover the space with kraft paper or grid cloth.

Second, after brushing the interface agent to clean up the base, we can replace the chisel by smearing the interface agent. After coating the interface agent, the construction process of wall painting technology can improve the adhesion of the grassroots and reduce the phenomenon of wall hollowing.

Third, the smoothness of the wall. When the wall is uneven, it must be leveled and filled with plaster to ensure that the horizontal error of the wall is within 3 mm

Fourth, more putty Once the wall is flat, you can start scraping putty. It is best to choose products with fine particles and hard ground as putty. Generally, wall putty should be scraped two or three times. The first layer of putty is thicker. This is to better level the wall. The construction technology of wall painting technology is that the second and third putty layers are relatively thin, and the paper makes the wall look softer. Pay attention to the emulsion when scraping putty. After scraping putty, be sure to wait until it is completely dry before scraping putty.

Five; Polishing Many people don't understand the importance of polishing, but it is very important to have a perfect paint effect. When polishing, choose a thin sandpaper to avoid leaving marks on the wall. After polishing, clean the wall to prevent dust from affecting the adhesion of paint.

6. Once the primer is polished, you can use the primer. When applying primer, make sure that all corners of the wall are evenly painted. The construction process of wall painting technology is that you can add a small amount of water to the paint to ensure that the primer is evenly applied.

After applying the primer, sometimes some flaws will be left in the polishing process, which is easy to find after brushing the primer. When these problems appear on the wall, we need to work on the wall. Sandpaper the wall and repaint it.

Eight, draw the top floor. When painting the top coat, you must follow the product requirements. The construction process of wall painting technology is to avoid affecting the effect of paint film. We should pay attention to brush corners and seams to ensure that uniform coating is not missed. The top floor usually needs to be painted twice. During construction, attention should be paid to the temperature of the construction site. When the temperature is too low, do not apply more, so as not to affect the film formation of the coating. If the construction period is short, it needs to be heated at the construction site.

The above is some information about the construction process of wall painting technology, I hope it is useful to you.
