Air pockets in wet paint cause cratering on the surface. When air bubbles rise to the surface, they burst, causing crater-like imperfections. You can prevent this by using the right paint gun speed, applying paint farther away from the surface, and in other ways.
This article will explain what causes air entrapment, how to prevent it, and what steps you can take to eliminate it.
When bubbles or air pockets in wet paint rise to the surface, they pop, which results in small craters. If paint is not applied in a way that prevents air pockets from forming, the surface will have tiny but noticeable imperfections.
Bubbles and air pockets can be caused by:
Trying the following things will help you achieve a smooth paint finish:
There are two ways to fix a paint surface that has craters:
Air entrapment can look similar to paint surface issues caused by a solvent pop or dust contamination.
Taking these steps will help you avoid and eliminate paint surface craters.
