Description
Zinsser Gardz Sealer Primer is a clear, water-based acrylic resin that penetrates deeply into porous surfaces. It forms a hard, moisture-proof film, preventing drywall blistering and bubbling. Ideal for damaged drywall, new plaster, and chalky surfaces, it seals in wallpaper paste and strengthens texture finishes. Suitable for high-pH surfaces, it ensures a sound base for painting or wallcovering.
