Mudcracking

DESCRIPTION
Deep, irregular cracks resembling dried mud in the dry paint film.
POSSIBLE CAUSES
  • Paint is applied too thick.
  • Paint is allowed to build up in corners during application.
  • Surface was not prepared properly; contaminants were not removed.
SOLUTIONS
Follow label and data page directions for the appropriate surface preparation.

Follow label and data page directions for the appropriate film build.

Determine the correct roller cover based on the coating being applied and the surface. On smooth surfaces, a mohair, 1/4", or 3/8" roller nap is usually sufficient. On textured surfaces, a 3/4" nap or greater is needed.

Smooth the coating by scraping and/or sanding, prime if needed, and repaint.

Quality paints have very good application and hiding properties, which minimize the tendency to apply too thick a coat of paint.
