1. Probable Cause / Reason:
• Rapid drying of the surface, forming a skin that wrinkles as the solvent evaporates from the underlying soft paint.
• Solvent evaporation is slower beneath the skin, leading to uneven drying.
• Use of excessive paint thickness or improper spraying technique.
• Environmental factors, such as temperature and humidity, contributing to rapid skin formation.
2. Correction:
• Apply a thinner coat to allow proper leveling and even drying.
• Use slower-drying thinners to extend the drying time and prevent premature skinning.
• Ensure application conditions, such as temperature and humidity, are within the recommended range for the coating.
• Modify spraying technique to prevent over-application.
3. Corrective Action:
• Remove the affected paint film and ensure proper surface preparation.
• Reapply the paint with a thinner layer and adjust drying conditions.
• Monitor and adjust spray conditions to avoid premature skin formation.
