The construction of putty powder can be roughly divided into two parts.
Puttying powder generally needs three times.
The second time of scraping is for further leveling.
During the specific construction, the workers’ methods are not necessarily the same.
As a common wall priming material, the production of putty powder has been relatively mature.
After the second scraping, collect the slurry slightly, then scrape for the third time, and then start calendering to achieve the effect of brightness and firmness.
Precautions: when applying putty, avoid the direct blowing of cold air.

Before painting on the wall, it is generally necessary to scrape and prime with putty powder.
If you apply paint in this way, when heating in winter, the original dry wall materials will begin to evaporate, showing a “dry crack”.
Special attention should be paid to: it must be dried thoroughly, otherwise it will seriously affect the subsequent construction effect.
The third scraping is the most important link, that is, calendering the putty powder.
The first is the cleaning of the base course, which is to better connect the putty powder with the wall and lay a solid foundation for the next step.
The second is the scraping of putty powder.
The first time is mainly for priming.

The second time of putty mixing is not easy to be too thin, so as to ensure that the water after scraping the second time of putty is absorbed by the first time of putty as soon as possible.
Brightness and strength coexist.
However, even if there is no problem with the quality of putty powder, the project effect may still be negatively affected by construction problems.
The drying time of the first pass is normally 24 hours, but the specific time varies due to wall conditions and climate conditions.
Although it seems to dry the wall, it actually locks the water in the wall.
We respect originality,.
