Generally, 0.5 ~ 1 hour after scraping is the best wet grinding time (polishing with water mill, and painting can only be carried out after the water vapor dries out). 2 ~ 3 hours is the best dry grinding time. After grinding, the dust on the surface can be removed, and subsequent operations such as painting, topcoat and varnish can be carried out. For occasions with high requirements, it is necessary to scrape putty (red ash and filler ash) to fill tiny defects after polishing putty, then spray the display layer and polish it to check tiny defects, and then carry out subsequent spraying.
