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.

Sizes & Coverage

5 Litre
Coverage: 7.4–9.8 m² per litre, depending on surface porosity and condition

Surface Preparation
Ensure the surface is clean, dry, and free of loose paint, dust, grease, or mildew. Remove flaking or chalking areas, but do not sand back to the bare substrate unless necessary. For best adhesion, lightly wipe down the surface with a damp cloth and allow it to dry.

Mixing
Stir Peel Stop thoroughly before use to ensure uniform consistency. Do not think the product can be applied directly from the container.

Application
Apply using a brush, roller, or airless sprayer in a uniform coat. Work systematically across the surface, ensuring coverage of edges and corners. Multiple light passes are preferred for textured or porous surfaces to avoid pooling.

Drying & Recoating
Touch dry within 1 hour at 18 °C. Surfaces can be recoated after 2 hours. Complete cure occurs in 7–10 days.

Coverage
Approximately 7.4–9.8 m² per litre, depending on surface porosity and condition. Adjust the application rate for rough or highly absorbent substrates.

Clean-Up
Clean brushes, rollers, and tools immediately with warm, soapy water before the product dries. Dispose of any unused product in accordance with local regulations.

Pro Tips for Best Results

Avoid application in direct sunlight or on hot surfaces.
Apply on stable weather days for exterior use to prevent premature drying or rain interference.
Test on a small, inconspicuous area if the surface condition is uncertain.
After the recommended recoat time for heavily peeling surfaces, a second coat may be applied.
