Factors Affecting Spray Paint Shelf Life

Temperature

Spray paint should be stored in a cool, dry place, ideally between 60°F and 80°F. Extreme temperatures can cause the paint to separate or become unusable.

Humidity

High humidity levels can cause the paint to clump or become sticky. Keep spray paint in a low-humidity environment to prevent these issues.

Exposure to sunlight

Direct sunlight can cause the paint to break down over time. Store spray paint cans in a dark, cool place to extend their life.

Tips for Proper Storage and Usage

  • Keep spray paint cans upright to prevent leakage or clogging
  • Regularly check the storage area's temperature and humidity levels
  • Shake the can well before use, as this helps mix the paint and maintain its quality
