How soon can metal steel be painted after sandblasting?

　　How soon can metal steel be painted after sandblasting? If abnormalities occur, what additional surface treatment is required?

　　Immediately after shot blasting, sand blasting or grit blasting, the surface must be cleaned with a soft cloth or chamois. Wait, the paint job must be completed quickly. Paint coatings will adhere to new surfaces very effectively, giving them a long life.

　　In fact, the wear of the paint coating depends on the quality of the base metal preparation. For the best surface finish, the life of the paint coat should stay in. If there are contaminants, the quality of the paint consumed will be greatly reduced.

　　In summer, in a closed atmosphere, a one-hour interval may be given. In winter, the time interval should not exceed 30 days. It is the rainy season and the duration should not exceed 15 days. For further removal of contamination, areas where rust is found should be selectively scrubbed with fine sandpaper and wiped clean with a cloth.

　　If delays are expected, it's a good idea to spray ethanol on the metal surface, scrub it with sandpaper, and then clean it with a muslin cloth. In short, the best way is to paint the metal immediately after sandblasting.
