Mud cracking

Mud Cracking

This refers to the deep, irregular cracks – resembling dried mud – that may occur in the dry paint film.

POSSIBLE CAUSES

• Paint is applied too thickly, usually over a porous surface.
• Paint is applied too thickly in an attempt to improve the coverage of a lower-quality paint.
• Paint is allowed to build up in corners when applied.SOLUTION
  Remove the coat of paint by scraping and sanding; then prime and paint the surface with a top-quality water-based paint, which has a higher solids content and is more flexible than solvent-based, and ordinary water-based, paint. It also has very good application and hiding properties, helping to eliminate the tendency to apply the paint too thickly.

  Alternatively, sand the surface smooth and repaint it using a top-quality water-based paint.
