Zinsser Gardz is a water-based penetrating sealer designed for porous and problem interior surfaces. It soaks deeply into chalky, crumbling and damaged substrates, drying to a hard, moisture-resistant film that seals and stabilises surfaces before decorating.
Ideal for repairing torn drywall paper, sealing residual wallpaper adhesive and protecting new plasterboard, Gardz binds down textured finishes and skim coats to prevent further surface damage. Fast-drying and easy to apply, it provides a reliable foundation for your next decorating project.
