Dust particles
Paint Defects
Causes
- Poor cleaning of substrate prior to painting
- Lint containing overalls or clothes
- Spray booth dust problem due to dirty filters causing incorrect air supply, extraction and pressure
- Intake of contaminated air from outside the spray booth (polishing residues, fine dust etc.)
Prevention
- Thorough cleaning before application of new paints
- Use lint-free overalls and cloth
- Ensure regular maintenance and filter changes of the booth
- Ensure polishing/finishing areas are away from the paintshop and separated by filtered and ventilated systems
How to repair
- Polishing with a propriety high gloss polish. More extensive defects are to be sanded down for re-painting
