mud cracking
MUD CRACKING is deep, irregular cracks resembling dried mud in the dry paint film.
POSSIBLE CAUSES:
- 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
SOLUTION:
- 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
