1, water on the wall: It turns out that the wall is covered with water, which saves labor when shoveling.

2. Shovel the wall skin: remove the flooded part of the original wall until the putty layer is exposed.

3, grinding: try to use fine sandpaper, if the sandpaper is too thick, it will leave a deep sand mark, which can not be covered with paint. The polished wall must be thoroughly cleaned to avoid too much dust and affect the adhesion of paint. The concave-convex difference shall not exceed 3mm.

4. Thin the putty: It is better to choose a putty with high particle fineness and hard texture, or add some white latex to the putty to improve the hardness of the putty.

5, dry and then grinding, the same method.

6. Primer: Primer must be brushed evenly to ensure that every part of the wall is brushed. If the wall eats a lot of paint, it is best to add a little more water to the primer to ensure uniform brushing.

7. Topcoat: Do not add too much water, which will affect the thickness, feel and hardness of the paint film. Try to choose better tools. The hair of the roller should not be too short, but it must be thin, so that the paint film drawn will have a delicate feeling. When painting, pay attention to the corner, the indirect stubble in each drum and the direction of paint collection. In most cases, we use combination brush or brush to draw corners, which will easily lead to the inconsistency of corner texture with the whole surface. If you have the conditions, you can buy an edge roller and then use the edge roller to close the corners. Note that the material of the edge-receiving roller should be the same as that of the roller with large brush surface. When painting a large surface, the paint at the next planting place must be collected evenly, neither too thick nor too thin, otherwise the reflection will be inconsistent due to uneven thickness. When painting, every time you roll on the wall, there will be a paint collection action, which requires the paint collection direction to be the same. (suggestion: buy a tray before painting, which will be sold in the store. Using the tray can ensure that the paint on the paint roller is the same every time, which will brush evenly. )

8. Care: Latex paint will dry within 4 hours after painting, but the dried paint film has not reached a certain hardness. This needs to be careful. It's simple. Do not scrub or touch the wall for 7- 10 days.
