WRINKLING

Shriveling, Crinkling

The surface of the paint contains irregular grooves or ridges resembling the skin of a prune.

CAUSE

• Excessive film thickness or "piling on" of heavy wet coats.
  
• Placing a newly painted finish in hot sun too soon after spraying.
  
• Using lacquer thinner to reduce synthetic enamel.
  
• Spraying in extreme hot, humid weather conditions.
  
• Under reduced and/or too fast evaporating thinner/reducer for spray conditions.
  
• Air pressure too low during spray application.
  
• Force drying of air-dry enamels without the recommended additives.
  

REPAIR

If defects are minor; Sand the top surface smooth, allow to cure and refinish.

If defects are severe; Remove the affected area and refinish.

PREVENTION

• Avoid excessive film thickness and heavy coats. Always allow for sufficient flash times.
  
• Keep newly painted finish away from direct sunlight until finish has dried/cured.
  
• Use reducer that is specifically recommended for the topcoat.
  
• Use the recommended reducer, additive, and/or retarder when spraying in hot humid weather.
  
• Select recommend thinner/reducer based on temperature, humidity, air movement, and size of repair.
  
• Use the proper reduction ratio and spray at recommended air pressure.
  
• Select the recommended additives to suit drying conditions. Follow force dry temperatures and time recommendations.
