What Causes Paint Cratering?

What is the source of paint cratering? Before the drying process can begin, craters and pinholes are formed by liquid or solid contamination that has been present on the substrate, in or on the paint, or in the surrounding environment. The differential in surface tension between the liquid paint and the contaminant is responsible for the development of craters.

Carrier craters are created by contamination with a low surface tension that is present on the substrate being painted, in the paint, or that falls on the paint. This results in a surface tension gradient, which causes flow away from the low surface tension area, resulting in a circular low patch on the surface of the water (see Figure 1 for an example).

What is cratering in paint?

Cratering, sometimes known as craters, is a condition in which paint on a coated surface has retreated, frequently in a concentric pattern, leaving a place where there is no paint. Crating is caused by incompatible foreign elements that can be found either within or on the surface of a painted surface.

What is the reason for the formation of craters?

The differential in surface tension between the liquid paint and the contaminant is responsible for the development of craters. Surface tension variations enhance the likelihood of such faults occurring.

How do you fix paint dimples?

If the fault is only superficial, the procedure is as follows:

  1. Use a sander and an abrasive disc with the P1500 grit to begin sanding, increasing the grit as necessary.
  2. Once the fault has been eliminated, polish the surface of the component using an abrasive polish before applying a brightening polish on top of it.
