Reciprocating scraping method
First, the putty is painted on the edge of the plane in a line, and the tip of the scraper is pushed outward at an angle of 30 45, and the putty is painted on the depression, and the excess putty is squeezed into the right side of the scraper mouth in a line. When the scraper is scraped to the front end, the tip of the knife is folded back at an angle of 35 and 45, and the putty is scraped to another depression, and the excess putty is on the right side of the scraper. In this way, the whole surface is filled back and forth. This method is suitable for scraping metal plates.
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.
Scraping method of circular object
The putty for circular objects can be scraped with a rubber scraper. Because rubber is elastic, the rubber scraper can scrape putty into a round layer with the deformation of the round surface, and so can other scrapers, but the skills should be mastered.
Blow putty completely
That is, the surface of the object is completely scraped off. Need to decorate the surface, especially so; 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.
Local embedding method
For surfaces with defects such as large holes and low requirements for surface smoothness, local scraping or repair can be adopted.
