The wall covering at home is peeling off, and the thickness of the falling wall covering is three to four millimeters? !
Is there any way to solve it?
In this case, there is no good way, but to shovel all of them and deal with it again!
This situation is typical when the putty is shaved too thickly.
This is also a misunderstanding of many owners.
I feel that the more times the wall putty is shaved, the better.
In fact, this is not the case! ! !
Many owners will ask whether the wall surface should be scraped twice or three times.
If you tell the owner to scrape twice, many owners may feel that we are saving materials, so why not scrape three times.
In fact, the putty layer is not as thick as possible! !
Putty does not have much effect on wall leveling! ! !
The biggest role of putty is to play the role of the base layer, because the putty is relatively soft, easy to polish, and easy to brush latex paint later.
The real leveling effect on the wall is gypsum powder.
According to the normal process, you need to level with plaster, and then scrape the putty on the plaster surface, so that the wall can be firm and not easy to fall off.
01
Before scraping the putty, check if the wall has returned to alkali
The picture will not say what factors cause the wall to return to alkali
Whenever you encounter the phenomenon of whitening and sanding on the wall, you must wash the wall first, wash it with grass acid, and then scrape the putty after it is dry, otherwise the wall skin will fall off in the future~
02
See if the putty is dry every time the master shaves the putty
It is inevitable that some decoration teams start to scrape the next layer before the first floor is dry in order to catch up with the construction period.
The water in the putty cannot be completely volatilized, and cracks and hollow drums are prone to appear.
In general, after the first putty is slowly dried in the shade, the second layer can be scraped.
03
After the putty is scraped, is there any careful inspection?
After scraping the putty, look at it with a searchlight at night, pay attention to it at night! Not broad day! Close to the wall, you can clearly see the polishing situation, and then see if there is an empty drum.
Once you find that it is not done, quickly find a master to repair it, otherwise it will be difficult to rework after the paint is applied!
