Knockdown Texture

A drywall texture that is created by adding water to joint compound to thin it and then spraying through a drywall spray hopper powered by an air compressor onto the ceiling or wall. After a short time the finisher comes back and flattens out the globs of joint compound with a special lexan blade giving a modern desirable appearance. Most popular in Southern USA and Western USA not as common in the Northeast where smooth is preferred.
