Essentially the same composition as joint compound, Knockdown is a thinned-out formula sprayed in a consistent and uniform pattern, then smoothed or sanded flat.

Knockdown is very useful in masking imperfections in walls and ceilings while providing a modern and sweeping look. After applying knockdown texturing, the compound must then be sealed and painted as it only covers about 75 percent of the drywall surface with the finalized painting covering up any of the uncovered background.
