How to turn over the old and new latex paint walls

Hello, I'm Mianyu, and I have different wonderful information to share with you every day.

Today, let's talk about it. Walls get dirty easily when painted for a long time. Can you draw again?

Of course. Let's talk about it in detail.

Before the first painting, clean up the whole old wall, polish the wall with sandpaper, so that there will be floating powder on the surface, and then sweep it away. Fill in the concave part of the wall with putty first, and then apply putty as a whole after leveling. When the front is dry, brush with mucilage, and wait for half a day, you can brush wall covering for the first time. When it is dry, apply putty powder, and then you can apply the strong cloth for the second time. Don't let the dust get on it in the meantime! Get ready.

Second, protect the door and window frames: paste color separation paper to protect the joints of doors, window frames, furniture and paint. Finished wooden cabinets, partitions and other furniture should be sealed with newspapers to avoid paint dripping and soiling the furniture.

Attention should be paid to the color matching of paint: for the wall with color requirements, the area should be accurately calculated in advance, and the materials should be evenly mixed at one time. Brush the wall surface primer: the wall surface should be primed before the top coat, which can prevent the wall surface from being damp, make the color of the top coat uniform, and prevent water stains caused by wood acid.

Third? Don't underestimate the construction details.

Roller coating: topcoat construction sequence: ceiling, line first, then wall. The walls should be painted at least twice. For the first time, 5- 10% water can be added to the paint to facilitate wall absorption. No water can be added to the second coat, and there is a certain interval between the first coat and the first coat.

Tips for construction tools: when roller coating, you need to use both thick and thin rollers at the same time, first use the coarse roller and then use the fine roller. Coat the paint evenly on the wall with a coarse roller, and brush it again with a fine roller where the coarse roller has brushed it, so that the wall paint becomes fine and the required pattern is brushed. Be careful not to stick too much paint on the roller when roller coating, and the roller coating pressure should be uniform and the speed should be moderate. Horizontal, vertical and inclined directions shall be evenly rolled.

Fourth, the repair details after construction

Brush repair: Generally, after painting with a roller brush, it is necessary to use a brush to repair the missing parts of the wall and corner, especially the joint position of the wall and corner line, wooden cabinet and partition. And the corner.

Wall polishing: After the wall paint is dry, use sandpaper to polish the wall to reduce brush marks and make the wall smoother. Pay attention to feel the smoothness of the wall surface from time to time when polishing, so as to judge where to polish, and the polishing strength should be moderate and the scope should be wide.
