Substrate Temperature and Application Conditions

  • Coating performance is, in general, proportional to the degree of surface preparation
  • Abrasive blasting is usually the most effective and economical method. When this is impossible or impractical, coating can be applied over mechanically cleaned surfaces
  • All surfaces must be clean, dry and free of all contaminants, including salt deposits. Contact PPG for maximum allowable salt containment levels
  • Surface temperature during application should be at least 3°C (5°F) above dew point
  • Ambient temperature during application and curing should be between 4°C (40°F) and 50°C (122°F)
  • Relative humidity during application should not exceed 85%
