Questions and Answers for Zinsser 1 gal. Odor Killing Interior Primer

A:  Happy to clear things up, Heather! Since most wood stains are penetrating, you will likely need to stain the floor prior to applying Rust-Oleum Zinsser Odor Killing Primer. Make sure the stain is applied as directed and allowed to fully dry prior to applying this product. This primer can then be topcoated with the floor polyurethane of your choice. - Rust-Oleum Product Support 3

A:  Happy to help, Steve! Yes, Rust-Oleum Zinsser Odor Killing Primer can be used on interior walls. Since this is a primer, it will require a topcoat for full durability and performance when used on a wall. - Rust-Oleum Product Support 3

A:  Happy to clear things up, Charlotte! While Rust-Oleum Zinsser Odor Killing Primer can be used over most finishes and can be topcoated with a polyurethane, the shellac on the surface now may need an additional sealer to allow it to be coated over. Most shellac finishes, such as our Bulls Eye Shellac, contain wax and can prevent paints and most other finishes from properly adhering. If this is the case, we recommend applying a coat of Rust-Oleum Zinsser Seal Coat Universal Sanding Sealer to ensure full adhesion. https://www.homedepot.com/p/Zinsser-1-gal-Universal-Sanding-Sealers-2-Pack-851/202057181 - Rust-Oleum Product Support 3
