Zinsser Gardz High Performance Sealer is a specialist sealer and bond coat specifically designed for use on porous surfaces such as new or old plaster, plasterboard, wallpaper, lining paper and filler. GARDZ can be used to size new plaster just 24 hours after application.
It can also be used to seal old plaster, filler and joint compound, preventing patchiness when painted.
Another use for Zinsser GARDZ High Performance Sealer is to repair torn or peeling plasterboard and wallpaper, producing a uniform moisture resistant film that’s great for further painting or papering. Zinsser GARDZ not only repairs, it also protects surfaces by creating a tough, hardened layer that’s extremely durable.
