Zinsser Peel Stop is a clear, flexible, binding primer designed for surfaces that are peeling, chalking, or cracking.
Even after painted surfaces have been scraped and sanded, tiny cracks and gaps remain under the edges of old paint. Zinsser Peel Stop seeps into these spaces and ‘glues’ them down, forming a tight bond that helps stop future peeling. The special formula of Peel Stop penetrates and binds chalky residues. Applied over cracked or crazed surfaces, Peel Stop acts as a flexible bridging primer to seal face crazing and prevent the finish coat from cracking, providing a sound surface for primer and paint. Glues down edges of old coatings. Seals and bridges cracking and checking. Binds chalky surfaces. Flexible / breathable. Recoat in 2 hours. Soap and water cleanup. Recommended for application to problem interior / exterior painted surfaces that exhibit chalking, alligatoring, cracking, flaking, and peeling.
Exterior Surfaces – Previously painted wood siding, windows, doors, fences, and trim; dry and denatured timber; metal gutters and downspouts; masonry siding, walls and foundations (inc. cured concrete, stucco, concrete block, brick, vinyl and galvanised siding, etc.)
Interior Surfaces – Previously painted drywall, plaster, cement, concrete, or stucco walls and ceilings; wood doors, windows, baseboards and trim.
Thorough surface preparation is very important. Surfaces should be clean, dry, sound and free of dust, dirt, grime, grease, oil, wax, mould, wallpaper adhesive, or any contamination that may interfere with adhesion. If unsure, always wash surface with an appropriate cleaning solution or solvent. Surfaces must be thoroughly scraped and sanded to remove all poorly adhered paint. Lightly sand exposed wood to remove loose fragments. Dull glossy painted areas with sandpaper. Spot prime areas where paint has been scraped or sanded off. In most cases only one coat is necessary. Excessively porous surfaces may require a second coat. Shake or stir well before using. Do not thin. Apply with brush and/or roller or airless sprayer. Back brush or roll to work Peel Stop into cracks and edges of old paint. Proper application of Peel Stop will dry to a slight sheen. Apply a second coat if dull spots appear. For best brushing performance use quality synthetic bristle brushes. Natural bristle brushes are not recommended for use with this product.
