Zinsser Peel Stop Flexible Paint Sealer for Problem Surfaces 5.0 kg

Zinsser Peel Stop is a professional-grade, flexible paint sealer designed to stabilise surfaces affected by peeling, flaking, chalking, or dusting. Formulated for both interior and exterior use, this clear bridging sealer penetrates and bonds to old or failing paint layers, creating a tough, breathable film that allows moisture to escape while preventing further peeling. Its unique acrylic chemistry binds cracking and chalking areas, extending the life of problem surfaces and providing a sound base for new paint applications.

Unlike conventional primers, Peel Stop forms a flexible membrane that moves with the substrate, ensuring long-lasting protection on wood siding, trim, yellow pine, rough-sawn cedar, textured plywood, stucco, concrete, concrete block, and galvanised gutters. Quick-drying and water-cleanable, it is easy to apply with a brush, roller, or airless sprayer.
