Zinsser B-I-N Advanced Shellac Primer, 1 qt – White | Rust-Oleum

Overview

Meet the Zinsser B-I-N Advanced Synthetic Shellac Primer from Rust-Oleum. This modern primer sealer combines the quick-dry strength of shellac with a contemporary water-based dispersion to deliver faster recoat times and a more comfortable indoor aroma. It supports both whole-surface interior priming and exterior spot priming, making it a flexible choice for builders, remodelers, and restoration projects.

Key benefits include superior odor sealing, exceptional stain blocking, a high hiding white base, and excellent adhesion. The formula is designed to seal knots, sap, and tannin bleed, helping you create a clean canvas before applying topcoats on a variety of substrates.

• Interior priming for new drywall, renovations, or water-impacted areas
• Exterior spot priming on weathered siding, trim, or outdoor wood
• Prevents stains from bleeding through the final paint and improves color fidelity

Fast, low-odor performance

The primer dries quickly and features a relatively low odor profile, which can reduce downtime between coats and improve comfort when painting occupied spaces.

• Fast dry time supports quicker project progress
• Low odor is friendlier for indoor environments
• Strong adhesion helps topcoats glide on smoothly

Versatile coverage and finish

Designed to provide high hiding power with a bright white base, B-I-N helps smooth out surface imperfections and creates a solid foundation for color coats. It seals knots and tannins, helping prevent discoloration in the final finish.

Usage guidance

Best used on wood, drywall, plaster, and common substrates encountered in new construction, remodeling, and restoration work (including fire or water damage scenarios). Always follow label instructions for mixing, application, ventilation, and drying times between coats.
