How to use the putty:
1. The surface to be scraped must be cleaned of oil, rust, old paint film, and moisture. It must be confirmed that it is dry and polished.
2. The main ash and the curing agent are uniformly formulated according to 100:1.5~3 (by weight) and used up in the gel time (the general gel time of the putty varies from 5 minutes to 15 minutes). The lower the temperature, the more the curing agent is used, but generally it should not be greater than 100:3. The atomic ash on the market has summer and winter types, and different types of putty are used depending on the seasonal temperature.
3. Scrape the adjusted atomic ash on the polished two-component primer or the surface of the pre-treated sheet with a spatula. If thick coating is required, it is best to scrape it to the desired thickness. If air bubbles penetrate during the application, it must be thoroughly smoothed with a spatula to ensure good adhesion. Generally, 0.5 to 1 hour after scraping is the best wet grinding time (water polishing, it needs to be sprayed after the water vapor is dry). 2 to 3 hours is the best dry grinding time. After polishing, remove the surface dust, and then spray the paint, top coat, clear varnish and other subsequent operations. For high-demand occasions, after the grinding of the putty, it is necessary to scrape the fine scrape (red ash, ash) to fill in the small defects, then spray the display layer and polish it to check the small defects, and then follow up. Spraying.
