Mud Cracking

Deep, irregular cracks resemble dried mud in dry paint film.

Possible Cause:

  1. Paint is applied too thickly, usually over a porous surface.
  2. Paint applied too thick, to improve hiding.
  3. Paint is allowed to build up in corners upon application.


  1. Mud cracking areas can be repaired by sanding the surface smooth, then prime, and repaint.
  2. Use high quality Latex paints as it has more flexibility than alkyd paints.
