Zinsser CoversUp™ Aerosol is a low odour vertical 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. CoversUp™ is an odourless solvent based formula with only a brief odour from propellants that diminishes quickly. Specification Size: 400ml.Colour: White.
