Zinsser Gardz Sealer Primer is a clear, water-based acrylic resin primer designed to seal porous interior surfaces like drywall, plaster, and wallpaper adhesive residue. It penetrates deeply to prevent blistering, bubbling, and mould growth, creating a moisture-proof film that ensures smooth, even topcoats. Ideal for preparing damaged drywall, new plaster, chalky paints, and textured finishes, it dries fast, is washable, and offers odour-blocking properties. This 1-litre primer covers approximately 15 square meters per litre, making it a reliable choice for DIY projects and professional redecorating.
