Cracking and Flaking

Cracking, splitting, flaking, or chipping paint is usually caused by a loss of elasticity in underlying layers, most often due to inadequate adhesion from poor preparation. 

Cracking and flaking paint 


  • Paint was applied to bare wood without priming first.
  • Paint was overly thinned or spread too thin.
  • Latex paint dried too fast because it was applied under cold, windy, or very hot conditions.

What to do:

  • Completely remove the failed paint down to bare wood and sand the surface. Feather sand any surviving paint so there is a smooth transition to the bare wood, and remove the dust with a tack cloth. Prep with an exterior latex primer and repaint with exterior latex paint.
