First, do you want to shovel off the decorated wall?
1, when serious problems such as cracking, peeling, hollowing and falling off occur on the wall surface, this is basically a problem of the wall surface at the grass-roots level and must be shoveled and redone.
2. If the test feels blank, or white water will flow when spraying water, this is basically a problem with putty and should be shoveled off.
3. If the wall quality can pass the test, there is no need for the owner to completely tear it down and redo it. You can put putty on one side. This can not only save part of the decoration budget, but also the quality of some second-hand houses is good, so there is no need to shovel and redo them.
Second, the steps of wall treatment
1, wall foundation inspection
Before you start, you need to check the foundation of the wall to see if it is flat and solid and if there is any hole. If there is a serious problem, you should report it to the developer. You can test the water resistance of the white wall. If the water resistance is not good, shovel it before doing it.
2, finished product protection
The protection of finished products also belongs to the preliminary work. If carpentry and floor tiles have entered the site, the owner needs to do a good job of protection. Dust, paint, etc. can easily pollute articles.
3, sealing layer processing
It is to block the base, which can prevent the accumulation of floating soil or dust and increase the construction difficulty. One is to fill cracks, holes and gaps with gypsum products, and the other is to seal thermal insulation walls, loose walls and cracked walls with kraft paper, and choose any one according to the situation.
4. Leveling treatment
If the flatness of the outer surface of the wall is poor, with a difference of more than 5mm, leveling is needed, so that only one batch of scraping is enough for construction, but it should be as thin as possible, and too thick will easily lead to the later cracking of the wall.
5, brush primer
After grinding the thin sandpaper, clean the dust on the wall and then brush the primer. Generally, it only needs to be constructed once, but it takes 2-4 hours to dry evenly and thoroughly before the next step can be carried out.
Step 6 brush the top coat
Then coat the surface and coat it twice. After the second drying, the next process can be carried out, which usually takes 2-4 hours. Of course, it depends on the weather. It takes 1-2 days for the second brush to dry completely. Pay attention to dustproof, sunscreen and waterproof in the process.
8. Accept
Only the acceptance is left, and the qualified ones should be smooth, crack-free, pinhole-free, uniform in color and full in paint film.
