GARDZ® by Zinsser
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. A typical application for GARDZ is on wallboard after the removal of wallcovering. GARDZ fights wall board paper delamination and potential bubbling. GARDZ has been reviewed and approved by TRIARCH as a substrate preparation material and maintains all applicable Triarch product warranties.
