This high-performance formula blocks even the most stubborn stains and odors—whether caused by water, smoke, pets, grease, ink, or fire damage—helping you start fresh with every coat. Designed for use on a wide variety of surfaces including drywall, plaster, wood, metal, vinyl, and masonry, it adheres tightly without the need for sanding and dries lightning-fast, ready to recoat in just 45 minutes. Its powerful sealing properties create a smooth base that enhances paint coverage and helps reduce the number of topcoats required. From sealing porous surfaces and wood knots to covering dark colors and offensive smells, B-I-N delivers professional-grade results whether you’re restoring damaged areas or prepping trim, cabinets, or furniture. Ideal for homeowners, painters, and contractors, this shellac-base primer is especially trusted for smoke and fire restoration jobs, offering long-lasting odor control and a clean, sealed finish.
