• Manifestations
  1. Term is used to describe patterned cracking on the paint’s surface.
  2. It is named for resemblance to scales on the skin of an alligator.
• Causes
  1. Applying an extremely rigid coat of something similar to alkyd enamel over a coat of something more flexible, such as a latex primer.
  2. Applying a top coat before undercoat has dried adequately.
  3. As the natural aging process of oil-based paint occurs, the elasticity of the paint film is lost due to constant expansion and contraction caused by temperature fluctuation.
• Solutions
  1. Completely remove old paint by scraping the surface, followed by sanding.
  2. Use a heat gun to facilitate faster results on large surfaces.
  3. WARNING: When using a heat gun be cautious not to ignite paint or substrate.
  4. Prime the surface with premium quality latex or oil-based primer.
  5. After drying, apply the highestquality exterior latex paint.
