How to paint the wall with paint

1, check and clean the epidermis.

Before painting the wall, we need to conduct a comprehensive inspection of the wall to see if there is pulverization, cracking and peeling on the wall. Clean up the base of the wall first. If it is an old wall, remove the damaged part first. Then clean up the stains, dust and floating soil on the wall.

2, brush interface agent

If the plaster mortar has poor adhesion to the wall, it is likely to cause the wall to bulge in the later stage, so brush the interface agent. The main function is to enhance the adhesion and waterproof function of the wall, because it has strong water resistance. Therefore, special attention should be paid to the construction method in the construction process, otherwise improper operation will also cause certain damage to the wall.

3, blow be bored with child leveling

Scraping putty and leveling can make the wall more flat. This step emphasizes the consistency of the overall decoration. To scrape putty well, the choice of putty is the key. When buying putty, try to choose brand putty with high particle fineness and hard texture. In order to achieve a smoother effect, putty needs three processes, and the overall thickness should not exceed 3 mm Remember: the previous process needs to be dried before the next process can be carried out.

4, grinding and repair

After the putty is finished, there will still be rough and abrupt places on the wall. Sandpaper comes in handy at this time. Sandpaper can be used to polish the wall surface, and then the corresponding sandpaper can be selected according to the texture of putty, which can have better polishing effect.

5. Formal painting

Painting is divided into primer and topcoat. Many people think that the primer need not be brushed. In fact, primer plays a very powerful role in protecting topcoat and alkali sealing. Primer needs to be brushed three times (still remember: each process is dry before the next process), and then the top coat is brushed. The painting method of top coat is basically the same as that of primer, and it can be brushed twice, that is, "one bottom and two sides".
