Regardless of whether it is a new house or an old house, the bottom plaster leveling needs to be carried out after the wall skin is removed.
Precautions for plaster leveling.
First brush the wall solid, and then the yin and yang corners of the position with PVC yin and yang angle strips, new walls, light walls, construction holes, trunking positions paste grids, the use of high-strength gypsum batch scraping smooth error requirements within 5 mm, there are cabinets to do vertical flattening, and finally dry before putty construction.
3. 7 steps for plaster powder leveling the wall.
3. 7 steps for plaster powder leveling the wall.
Gypsum leveling is to use gypsum board or gypsum powder to mix with glue to fill the uneven area of the wall or ceiling surface. It can be partially leveled, without raising the ground, which is convenient for construction and cheap.

Seam treatment. When pasting seams at the junction of different materials, it is necessary to paste them flat and firmly.
The difference between plaster leveling and putty scraping.
Gypsum leveling and scraping putty have construction and material differences, which are suitable for internal wall construction, putty has different points of indoor and outdoor construction, and can be constructed according to their own needs. Gypsum is mostly used for local leveling, and putty is suitable for large-area batch scraping construction.
Fourth, scrape putty.
The oiler's work of scraping putty has a great impact on the flatness and cracking of the wall of decoration, and the following is the order and precautions for scraping putty.

5.All the yin and yang corners of the whole house need to be leveled with yin and yang corner strips.
6.The bare leakage of the steel bar should be treated with anti-rust.
Precautions for scraping putty:
1. The first putty and the second putty should be leveled with a level, and the problems of the wall should be solved when the putty is scraped for the first and second passes, and the putty can not have rust spots or putty blistering on the last putty.
