Zinsser B-I-N Advanced Interior Multi-purpose Shellac Wall and Ceiling Primer ( 1-quart )
Can this be used on smooth side of OSB for a shop prior to painting

We're happy to help! Yes, Rust-Oleum Zinsser B-I-N Advanced Synthetic Shellac can be applied to either side of an OSB board. We recommend lightly scuff sanding any smooth surfaces to help build a surface profile that allows for the best adhesion of the primer. -Rust-Oleum Product Support 14
