Happy to help, Alyssa! Rust-Oleum Zinsser B-I-N Shellac-Based Primer is an excellent choice for sealing and preparing surfaces for paint. However, if the stain is still tacky after a week, that is a sign there is excess stain remaining on the surface. Before applying any primer, all of the uncured stain must be thoroughly removed using mineral spirits and clean rags, then allowed to dry completely. Once the surface is clean, dry, and the stain has fully cured, the primer can be applied and top-coated as desired. - Rust-Oleum Product Support 16
So, if it needs removal, how would I do that?
Thank you for reaching out, Richard. While Rust-Oleum Zinsser BIN Shellac-Based Primer is ideal at masking odors, it sounds like the previous coat of paint may need to be removed. A poorly bonded or not fully cured base coat can hinder the long term adhesion of the following coatings. -Rust-Oleum Product Support 14
Danny, great question! Rust-Oleum Zinsser B-I-N Shellac-Based Primer is helpful when wanting to seal a surface when encountering water or tannin stains. Instead, we recommend using Rust-Oleum Zinsser Gardz Problem Surface Sealer to help with the torn drywall and to help seal it. https://www.homedepot.com/p/Zinsser-GARDZ-5-gal-Clear-Water-based-Interior-Problem-Surface-Sealer-2300/203325628 - Rust-Oleum Product Support 10
Alma, thank you so much for reaching out! Yes, both a water-based and latex paint can be applied over the primer. Ensure you allow the primer to dry for at least 45 minutes. As always, a test application should be done to ensure favorable results. - Rust-Oleum Product Support 10
We're happy to clear things up! Rust-Oleum Zinsser B-I-N Shellac-Base Primer is suitable for only spot priming on exterior wood for knots in the wood but cannot be used for entire exterior applications. Instead, we recommend using Rust-Oleum Zinsser Cover Stain Oil-Based Primer. This primer can be topcoated with an exterior latex paint after 1 hour. For best adhesion, the primer should be topcoated within 7 days. https://www.homedepot.com/p/Zinsser-Cover-Stain-1-qt-White-Oil-Based-Interior-Exterior-Primer-and-Sealer-3504/100398403 — Rust-Oleum Product Support 15
Good question, Pat. Rust-Oleum Zinsser B-I-N White Shellac-Base Primer is not recommended to encapsulate black mastic flooring. B-I.N. is designed as a stain-blocking and bonding primer for surfaces such as wood, drywall, and previously painted surfaces. It has not been tested or approved as a mastic encapsulant or flooring underlayment. Currently, Rust-Oleum does not manufacture an encapsulating product for this purpose. — Rust-Oleum Product Support 15
Doug, we got you covered! After using Rust-Oleum Zinsser B-I-N Shellac Primer, wash application tools in a solution of 1 part ammonia and 3 parts water immediately after use. If primer has dried on application tools, soak tools overnight in a solution of equal parts ammonia and water. - Rust-Oleum Product Support 10
Happy to help, Arturo. While Rust-Oleum Zinsser B-I-N Shellac Based Primer seals odors and tannin bleed through knows, it has not been tested to seal adhesive. We recommend first applying a test application to ensure the results are as desired. -Rust-Oleum Product Support 14
