Many people are not very clear about wall painting, so what are the precautions for wall painting? How to brush the wall? Let's take a look with Bian Xiao.

First, what are the precautions for wall painting?

1, pay attention to the weather.

Before painting the wall, in order to avoid rain and snow, the mildew, oil stains, floating ash and loose paint on the wall must be thoroughly removed, the wall surface should be shoveled clean, and then polished with coarse sandpaper to repair the leakage in time.

2. Don't miss the pen.

When painting decoration, you can use the method of vertical brush from top to bottom or horizontal brush from left to right. In order to avoid stripes of different shades on the wall, lime slurry needs to be constantly stirred during brushing.

3. Pay attention to the acidic colored wall powder such as fruit green and sky blue.

In order to avoid mottling on the wall surface, the outer layer of lime can only be painted and decorated after the newly painted paper reinforced gray wall surface is completely dried. In addition, the problem of neutralization and floodlight should be paid attention to when adding acid colored wall powder to lime walls that have not been painted for more than half a year.

Second, how to brush the wall?

1, check whether the painted wall is solid and flat.

Measure the painted wall with a measuring ruler of 2M or more. If there are cracks and holes in the wall, it is recommended to find a developer or property to redo it. A single hole can be filled with gypsum.

2, the preparation work before blowing putty

After confirming that the wall is solid and flat, clean it with tools such as steel brush to avoid floating soil and ups and downs as much as possible. Evenly coat the concrete interface agent on the wall, and scrape putty after 2 hours.

3, scraping water-resistant putty

Under normal circumstances, both sides of the wall are putty-scraped, and the flatness is poor, so it is necessary to scrape putty several times locally. You can scrape plaster for leveling first, and then scrape putty to cover the background color. At the same time, it should be noted that the time interval of scraping putty should be more than 2 hours.

4, polishing putty

After 2 days of putty scraping, you can choose bulbs above 100w to grind against the wall at night. Pay attention to check the flatness of the wall.

5, brush primer

After polishing, the float and sink on the surface of the putty are cleaned, and then the primer can be painted, which can be painted 1 time and must be uniform, and the next step can be carried out after 3 or 4 hours.
