Zinsser GARDZ Problem Surface Sealer is a clear, water-based acrylic resin sealer designed for interior application to porous surfaces prior to painting, texturing, or wallcovering. GARDZ is recommended for sealing problem porous surfaces such as bare or damaged drywall, plaster, cement and cementitious coatings, spackling paste and joint compound, calcimine, stucco, acoustic and texture finishes, and uncoated wallpaper. It is suitable for application to interior walls, ceilings, and related surfaces. GARDZ will also adhere to and seal in old wallpaper paste and adhesive residue. GARDZ has a milky blue-white color that helps to determine where it has been applied but dries clear.
