What tools are used to scrape putty and what are the methods to scrape putty?

Putty scraping is done before painting, so whether the paint is done well depends on whether the putty is scraped well. Putty (filled with mud) is a decorative material for leveling the wall, a thick slurry coating and an essential product before painting. So what tools are used to scrape putty, and what are the methods to scrape putty? Scraping putty requires a gray knife and trowel, and mixing putty requires a mixing electric drill. What are the methods of scraping putty? (1) back and forth scraping method. First, the putty is coated on the edge of the plane to form lines, and the tip of the scraper is pushed outward at an angle of 30 ~ 45 degrees, and the putty is coated on the depression, and the excess putty is squeezed to the right side of the scraper mouth to form lines. When the scraper is scraped to the front end, the tip of the scraper is folded back at an angle of 30 ~ 45, and the putty is scraped to another depression, and the excess putty forms a line on the right side of the scraper. This can fill the whole surface of the object, and this method is suitable for scraping and coating the plane body. (2) One-sided scraping method. That is, the scraper scrapes only one side, such as scraping from top to bottom, scraping from front to back or scraping from bottom to top. Scraping putty on the car body means scraping from top to bottom or from front to back. (3) Scraping method for circular objects. The putty for circular objects can be scraped with a rubber scraper. Because rubber is elastic, rubber scraping can deform with the circular surface, putty can be scraped into a circular layer, or other scraping methods can be used, but skills should be mastered. (4) Blow putty completely. That is, the surface of the object is completely scraped off. The surface needs to be decorated, especially. Sometimes it is necessary to combine local embedding to meet technical requirements. The putty for all-round scraping should be soft and easy to operate. (5) local embedding. For surfaces with defects such as large holes and low requirements for surface smoothness, local batch or embedding can be used. Partially embedded putty will be harder. That's all the knowledge about scraping putty. The above introduces several methods of scraping putty, which you can adopt. Here, I want to remind you that in order to keep the wall flat and smooth, we need to pay special attention to the treatment of the grassroots when dealing with the grassroots. After the treatment is completed, we will carry out putty scraping acceptance on the wall.
