B-I-N Advanced 1 qt. White Synthetic Shellac Interior/Spot Exterior Primer and Sealer (4-Pack)

Glad to lend a hand, Gary. Rust-Oleum Zinsser B-I-N Advanced Synthetic Shellac can be used under and over any latex or oil-based architectural paint. For priming wallpaper, we recommend using Rust-Oleum Zinsser Gardz instead. https://www.homedepot.com/p/Zinsser-GARDZ-1-qt-Clear-Water-Based-Interior-Problem-Surface-Sealer-6-Pack-2304/205145658 - Rust-Oleum Product Support 5

Great question, Jay! While Rust-Oleum Zinsser B-I-N Advanced Synthetic Shellac Primer and Sealer can be used on most surfaces, we recommend Rust-Oleum Zinsser Gardz Problem Surface Sealer for this instead. Once the surface has been sealed with Gardz, the B-I-N Advanced can be used to prime the surface. https://www.homedepot.com/p/Zinsser-GARDZ-1-gal-Clear-Water-Based-Interior-Problem-Surface-Sealer-4-Pack-2301/202596339 - Rust-Oleum Product Support 3

Happy to help. Zinsser B-I-N Advanced Synthetic Shellac Primer cannot be used over wallpaper glue residue. The correct primer to use is Zinsser GARDZ Problem Surface Sealer. https://www.homedepot.com/p/Zinsser-GARDZ-1-gal-Clear-Water-Based-Interior-Problem-Surface-Sealer-4-Pack-2301/202596339 - Rust-Oleum Product Support 6

If you're looking to take care of the mold, the Rust-Oleum Zinsser B-I-N Advanced Synthetic Shellac is not going to work well to continue to prevent or stop the mold. If you have a non-porous surface with mold, consider using the Zinsser Mold Killing Primer for your needs. If you have a porous surface, we do not have any other product we can suggest for mold. https://www.homedepot.com/p/Zinsser-1-gal-Mold-Killing-Interior-Exterior-Primer-276049/204994675 - Rust-Oleum Product Support 1

You can apply a primer such as the Rust-Oleum Zinsser B-I-N Synthetic Shellac Primer, but please be sure that the drywall mud had dried properly. You may need to test the application in an inconspicuous area to ensure desired results. - Rust-Oleum Product Support 1

We appreciate your interest! Rust-Oleum Zinsser B-I-N Advanced Synthetic Shellac Primer is suitable for use on interior surfaces or spot priming on exterior surfaces. We do not recommend it for use under floor paints or on exterior metal doors. Rust-Oleum Zinsser Bulls Eye 1-2-3 Water-Based Primer can be used on your door, but we do not recommend it for use on the porch due to the exposure to direct foot traffic. If wanting to use this primer on flooring, we recommend it on subflooring only. https://www.homedepot.com/p/Zinsser-Bulls-Eye-1-2-3-1-Gal-White-Water-Based-Interior-Exterior-Primer-and-Sealer-2001/100398391 - Rust-Oleum Product Support 3

Great question, Barclay. The Rust-Oleum Zinsser B-I-N Advanced Synthetic Shellac Primer can be applied over an oil-based polyurethane finish. Just make sure that the surface is thoroughly cleaned beforehand. - Rust-Oleum Product Support 5
