Description: Cause:
The paint viscosity is too low.
Too much thinner has been added, or a low-quality thinner has been used.
Poor adhesion of the primer or application of the topcoat over a primer that is not fully dry.
Application on a poor-quality substrate.
Prevention:
Use the correct type of primer and allow it to dry properly before applying the topcoat.
Add the correct amount of thinner according to the product instructions.
Ensure the paint is thoroughly mixed and applied under proper conditions using appropriate spraying techniques.
Properly prepare the substrate before painting.
