Causes

  1. Impurities due to paint residue/encrustation of the spray gun, paint hoses and clothing
  2. Overspray clusters (multicoloured particles) from the spray booth fall into the wet paint film. These particles often form at the ceiling of the spray booth due to incorrect airflow or clogged filters.
  3. Overspray from adjacent paint jobs.

  3. Keep jobs separate from adjacent paint jobs
