Questions and Answers for Zinsser GARDZ 5 gal. Clear Water based Interior Problem Surface Sealer

A:  Use this first to seal/smooth down torn paper, then mud/texture as needed, then use another mild primer before painting. If you specifically want mold prevention there is one in the Kilz brand.

A:  Great question! Rust-Oleum Zinsser Gardz Primer can certainly be used in a bathroom over torn drywall paper. However, it does not protect against mold/mildew. For that, you would need to use the Rust-Oleum Zinsser Perma-White Interior Paint. https://www.homedepot.com/s/perma%2520white?NCNI-5 - Rust-Oleum Product Support 5

A:  Happy to help! We recommend removing any loose primer on the surface and at least using Rust-Oleum Zinsser Gardz Sealer on the damaged areas. Gradz can be used on the whole surface, but any loose or blistering primer does need to be removed first, as this is not a binding sealer. - Rust-Oleum Product Support 3

A:  Skimcoat then apply Gardz for drywall. Tile should be going on cement board. Remove the drywall and install cement board to the studs.

A:  You can technically apply the Rust-Oleum Zinsser Gardz first and skim coat after; however, if you apply your skim coat first and then apply the Gardz product, it'll seal it all in. That's going to be your best case here if you're able. We hope this helps! - Rust-Oleum Product Support 1
