step 1: plastering refers to plastering the wall with a layer of lime and other materials, but before plastering, the surface of the wall should be fresh and clean, including cleaning the dust, loose objects, dirt and oil stains on the first wall, and cleaning the wall well.

if there are obvious concave and convex parts on the surface of masonry foundation, it should be leveled in advance and filled with 1: 3 cement mortar; Before plastering, the wall surface should be watered. Generally, the brick wall foundation will be watered twice, and the water seepage depth of the brick surface is about 8-11 mm, which can meet the requirements of plastering.

Step 2: Before scraping putty, you should first level the wall with gypsum, and do a good job of leveling the wall. Then it is time to scrape putty on the wall.

in the process of decorating the wall surface, scraping putty needs to go through many processes, and the materials used should also have a delicate feeling, and the putty materials should be evenly daubed on the wall surface to form a flat and neat decorative effect.

The general gypsum interface agent is about one kilogram of 2 yuan money, and a bag of 21 kilograms is 41 yuan money. It is thinly daubed on the cement wall, and the first putty project is completed.

the tools used are also special tools for painting putty on the wall, so if the owner needs to try painting putty himself, he doesn't have to worry about the poor handling of the putty layer on the wall.

Step 3: After the project of scraping putty with sand is completed, it is necessary to do the sand repair work on the wall next.

sand patching refers to finishing and grinding the wall that has been touched with putty once, and smoothing the uneven places in the wall.

sand patching is a hard and patient job. after the workers finish the sand patching, if the owner needs to check whether the wall is smooth, he can turn on the high-power light at night to check whether it is smooth and smooth.

especially in the details of the combination of doors, windows and walls, it is necessary to check carefully to avoid bubbles in the process of painting glue.

step 4: in the project of painting, you can directly roll paint twice, but generally, before painting, the wall will be coated with a waterproof putty layer, which can effectively prevent mildew and water leakage on the wall.

the spraying method is better, but you need to put a decorative putty (barreled decorative putty) on top of the water-resistant putty, spray a thin layer, polish it with 1211 mesh sandpaper, and then spray adhesive paint, and spray the paint only once.

if the wall decoration takes a long time and you want to make up the wall paint, you can spray it directly on the wall without removing the original paint.
