Dry spray on painted components

Formation of dry powders on painted componets results poor finish.

Remedies

• Avoid fast evapoating solvents in the spray thinners.
• Avoid spraying under hot sun.
• Mix some retarder thinner with spray thinner.
• If it is ordinary air drying alkyd based enamel add a few drops of pine oil. It stops fast evaporation.
• If it is NC based lacquer or acrylic paints, add a few mL of butyl cellosolve or butanol.
• Avoid spraying in the proximity of finished components.
• Use appropriate exhaust system.
• Your exhaust fan may need cleaning.
