Poor Opacity

How It Looks

Description of problem

The old paint or the ground coat is visible underneath the topcoat.

Causes

  • Paint was not stirred well.
  • Paint is over thinned.
  • Thinner is too slow which makes the paint run before the required thickness is achieved.
  • Thinner used is incorrect.
  • Not enough spray passes (too low film build).

Preventive measures

  • Stir the paint well.
  • Use appropriate thinning ratio.
  • Use appropriate thinner.
  • Spray sufficient topcoat to obtain opacity.

Remedy

Allow drying fully. Sand and repaint.
