Generally, the ceiling is installed first, and then the putty is scraped, because in the process of drilling the ceiling, a lot of dust will be generated and the wall will be dirty. If the ceiling installed at home involves carpentry, it is necessary to complete the main frame first, and then blow putty to avoid the dust generated by the ceiling polluting the wall.

Second, what are the precautions for blowing putty?

1, it is best not to be too thick at a time, and generally it is best to be around 0.5 ~ 1mm, in order to prevent the putty from cracking or peeling due to excessive shrinkage.

2, do not scrape back and forth, it is best to scrape in one direction to avoid curling or falling later.

3. If the base has strong adsorption, it can be sealed with some primer first, so that the adhesive of putty will not be absorbed too much, which will affect its adhesion.

4. There are certain requirements for the use of tools when scraping, such as how much the angle is inclined and whether the strength is uniform, so as to ensure the fullness of putty.
