Problem

Mud cracking

Cause

The most likely cause of mud cracking is applying a thick, heavy, unthinned coat of paint to a textured or embossed surface such as blown vinyl wallpapers or pebbledash. This is especially true if the paint was applied by brush.

Putting it right

One or two thinned coats of paints may fill in the cracks. For internal walls, a soft sheen paint is the most suitable product to use. If the affected area is over wallpaper, the best way to solve the problem is to remove the paper and start again.
