Zinsser 1 gal. Gardz Problem Surface Sealer

Zinsser Gardz Problem Surface Sealer is a high-performance, water-based acrylic resin sealer formulated for interior application on porous and damaged surfaces. It deeply penetrates and seals problem substrates prior to painting, texturing, or wallpaper installation, ensuring a solid foundation for topcoats. Ideal for repairing torn paper on damaged drywall, locking down old wallpaper adhesive, and sealing porous surfaces such as spackling, joint compound, plaster, stucco, and acoustic finishes. The low-odor formula dries quickly to a clear, hard moisture-resistant barrier that eliminates bubbles and protects surfaces.
