Dust inclusions

Usually small, irregular lifting of the paint film caused by foreign matter (e.g., dust/dirt) which can occur in different sizes, shapes, types and patterns.

Causes

1. Poor cleaning of substrate prior to painting
2. Lint containing overalls or clothes
3. Spray booth dust problem due to dirty and clogged filters causing incorrect air supply and incorrect overpressure
4. Intake of contaminated air (polishes, fine dust etc.) from other parts of the workshop

HOW TO AVOID

1. Clean thoroughly before applying the paint.
2. Use lint-free overalls and cloths.
3. Have air flow settings set by the booth manufacturer.
4. Ensure regular cleaning and maintenance of the spray booth and filters.
5. Ensure that polishing/finishing areas are away from the paintshop and are separated by a filtering and ventilation system.
