Smooth Application: This acrylic latex primer provides excellent coverage and seals surfaces for long-lasting topcoats with a smooth, thick formula that applies easily. Versatile Use: Suitable for use on interior walls, ceilings, woodwork and trim to promote adhesion of topcoats over drywall, plaster, wood and more. Stain-Blocking Formula: The milky white primer hides minor surface imperfections and blocks common stains like water marks, grease or tannin bleed-through from showing through the topcoat. Dries Quickly: Can be recoated in just 1 hour for fast project completion, with low odor as it dries to a soft matte finish that won't change the look of topcoats. Easy Clean-Up: Soap and water remove fresh primer from brushes, rollers, and other tools so no primers solvents are needed, making it safer for use around home and family.
