General Description – Covers UP Ceiling Paint & Primer in One is a low odor aerosol that is a stain killer and ceiling touch-up paint in
one. It seals water damaged ceilings and sprays vertically for ease of use. It’s perfect for touch up when you don’t want to repaint the
entire ceiling due to spot damage. Zinsser’s stain blocking primer technology is incorporated into this new generation product that
offers a flat white finish that matches most new acoustical ceiling tiles and white ceiling paints. Covers UP is an odorless oil-base
formula with only a brief odor from propellants that diminishes quickly.

dry two hours before recoating.

most ceiling tiles.

surface. May be topcoated with ceiling paint in two hours when used as a primer.
