How to paint over a sponged wall.
Sponge painting is an application technique that easily gives plain walls a colorful, dramatic effect. Simply painting over it without properly cleaning and preparing the walls only fixes the problem temporarily. You should consider applying an undercoat if you are working on new walls, have repaired scuffs or marks or you are going over existing paint that is. In some instances you may be able to remove the paneling and paint the walls directly.
