Zinsser Gardz is a high-performance, water-based sealer specifically designed for use on all porous surfaces such as new gypsum drywall, joint compound, and spackling. This product is ideal for both trade professionals and DIY enthusiasts aiming to achieve a uniform and smooth finish. Gardz penetrates deeply into the surface, creating a moisture-resistant film that effectively protects drywall from issues such as blistering and tearing during future redecorating.
Additionally, Gardz features good alkali-resistant properties, making it suitable for high pH surfaces. It can be used to seal a variety of materials, including damaged drywall, new drywall, spackling, joint compound, skim coats, plaster, calcimine, uncoated wallpaper, wallcovering adhesive residue, and textured paint finishes. For optimal results, ensure that surfaces are clean, dry, and free of contamination before application.
