Gardz Problem Surface Sealer is a unique water-base sealer for porous and potential problem surfaces. It 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 texture finishes.
GARDZ is recommended for: damaged drywall, new drywall, spackling and joint compound skim coats, plaster, calcimine, uncoated wallpaper, wallcovering adhesive residue, texture paint, popcorn ceilings and builder’s flat paint.
