Slow Drying
Description
The paint film requires an excessive drying period, or fails to harden thoroughly.
Cause
Slow evaporation of solvent from the paint. This may be due to:
- Excessive thickness of the paint film.
- Poor atmospheric conditions during spraying or drying, coldness, humidity, lack of air movement.
- Insufficient drying time between coats.
- Insufficient, poor quality or incorrect thinner.
Prevention
- Apply paint in thin web films.
- Ensure adequate warmth and ventilation. Avoid spraying in excessively humid conditions.
- Allow sufficient drying time between coats.
- Use the correct amount of recommended thinner.
Rectification
Move the vehicle to a warm, well ventilated area. Low heat may be applied to improve drying, but care must be exercised to avoid wrinkling.
