Zinsser Gardz Clear Coat
A unique water-based sealer for porous and potential problem surfaces. Gardz is formulated to deeply penetrate and dry to a hard, moisture resistant film that seals and binds down porous, chalky and crumbling surfaces, paints and textured finishes. Gardz takes the “problem” out of problem surfaces. Deeply penetrating, it dries to a rock-hard, water-resistant finish; this protects surfaces from damage during the next redecorating project. Gardz is recommended for damaged drywall, new drywall, spackling and joint compound skim coats, plaster, calcimine, uncoated wallpaper, wallcovering adhesive residue, textured paint and more
