Mud Cracking

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


Possible Cause :

• Paint is applied too thickly, usually over a porous surface.
• Paint is applied too thickly, to improve in herent poor hiding ( coverage ) of a lower quality paint.
• Paints is allowed to build up in corners upon application

Solution :

• Remove coating by scraping and sanding.
• Prime and repaint, using a top quality latex paint.
• Mud-cracking areas can also be repaired by sanding the surface smooth before repainting with a top quality latex paint, this type of paint is likely to prevent recurrence of mud cracking, because it is relatively more flexible than alkyd paint, oil based paint and ordinary latex paint.
• Quality paints have a higher solids content, which reduces the tendency to mud crack. They also have very good application and hiding properties, which minimize the tendency to apply too thick a coat of paint.
