What should we do if the paint is polluted and blistered?
1. Definition:
Pollution blistering: Also known as bubbles or "prickly heat", irregular blistering on the surface of the paint layer.
2. Cause:
① The main reason is that the substrate is contaminated, and proper cleaning and preparation work has not been carried out before painting.
②Contamination from air supply pipes or spraying tools.
3. Solution:
①Clean the sprayed surface and thoroughly remove substances such as wax, grease and polishing agent.
② Ensure that the tools such as compressed air, air supply pipes and spray guns are clean.
③ If prickly heat has occurred, lightly sand the surface, taking care not to wear through the paint film, and re-spray. In severe cases, sand to bare metal and re-spray.
