mud cracking

MUD CRACKING is deep, irregular cracks resembling dried mud in the dry paint film.


  • Paint is applied too thickly, usually over a porous surface
  • Paint is allowed to build up in corners during application
  • Paint is applied too thickly, to hide the inherent poor coverage of a lower quality paint


  • Remove mud cracking by scraping and sanding back to a sound, smooth surface finish.
  • Prime with Prominent Ultra Prime and repaint using a premium quality paint, for example, Prominent Premium Satin.
  • This type of paint is likely to prevent the recurrence of mud cracking, because it is relatively flexible compared to alkyd, oil-based and ordinary PVA paints.
  • Quality paints have a higher solids content, which reduces the tendency to mud crack.
  • They also have very good application and hiding properties, which minimise the tendency to apply too thick a coat of paint
