Zinsser Cover Stain Interior Oil-Based Primer - Product Information

📋 Product Description

Zinsser Cover Stain® is a high-performance, oil-based primer-sealer and stain blocker designed for both interior and exterior applications. It is a professional-grade primer known for its exceptional stain-blocking power, superior adhesion, and versatility across virtually any surface .

Key Features & Benefits:

  • Superior Stain Blocking: Effectively seals and blocks tough stains including water, smoke, fire damage, nicotine, graffiti, crayon, rust, and tannin bleed from wood . It is particularly recommended for sealing tannin-rich woods like cedar and redwood .

  • Exceptional Adhesion: Sticks to glossy and difficult surfaces without the need for sanding or de-glossing, including enamel paints, varnishes, paneling, laminates, ceramic tile, and metal .

  • Versatile Application: Suitable for use on wood, drywall, plaster, masonry (brick, concrete, stucco), metal (aluminum, steel, copper), vinyl, PVC, and previously painted surfaces . Can be used under both oil-based and water-based (latex) topcoats .

  • Odour Blocking: Specifically formulated to seal in and block odours associated with smoke, fire, and pet damage .

  • Fast Drying: Dries to the touch in 30 minutes and can be recoated in 1 to 2 hours .

  • Hides Dark Colors: Provides excellent hiding power for dark or bold existing colours .

  • Tintable: Can be tinted with up to 2 oz. of universal colorant per gallon for off-white or pastel shades .

Recommended Uses:

  • Interior: Previously painted drywall, cured plaster, wood, metal, glossy surfaces, cabinetry, and as a sealant for wallpaper before painting .

  • Exterior: New or previously painted wood, hardboard, metal, vinyl, PVC, and as a sealer for porous surfaces .
