Defect treatment of sandpaper

For defect handling, fine-grained sandpaper is generally chosen because it can better polish and smooth the surface, achieving the goal of removing defects.

Specifically, defects can be treated with sandpaper of specifications such as 800 mesh, 1000 mesh, 1200 mesh, etc. When using, appropriate sandpaper should be selected based on the degree of defects and surface material. First, use thicker sandpaper to polish off obvious defects, and then gradually use fine sandpaper for polishing treatment to achieve better results.

Please note that when using sandpaper for defect treatment, it is important to operate gently and meticulously to avoid excessive polishing or causing new damage. At the same time, one should also pay attention to protecting their own safety and avoid causing harm.
