This refers to patterned cracks in the surface of the paint film that resemble the scales of a crocodile.


  • Applying an extremely hard, rigid coating, like a solvent-based enamel, over a more flexible coating, like a water-based primer.
  • Applying a topcoat before the undercoat is dry.
  • The natural aging of solvent-based paints as temperatures fluctuate. The constant expansion and contraction results in a loss of paint film elasticity.

Remove the old paint completely by scraping and sanding the surface. A heat gun may be used on large surfaces to speed up the process, but take care to avoid igniting the paint or substrate.

Prime the surface with a high-quality water-based or solvent-based primer, and follow with two coats of a top-quality exterior water-based paint.
