Zinsser B-I-N 904 Shellac-Base Primer, White, 1 Qt.

Zinsser B-I-N is a shellac-base primer-sealer that permanently blocks tough stains, odors, and wood knots before painting. This original shellac-base formula is the reliable choice contractors keep on hand for interior prep work and spot exterior repairs. It solves the problems that standard primers cannot: stubborn stains that bleed through topcoats, persistent odors trapped in surfaces, and difficult-to-paint glossy finishes that require no sanding.

B-I-N can be used to block water, grease, rust, smoke, asphalt, graffiti, and many other types of stains. The shellac base ensures superior adhesion and fast dry times, letting you recoat in just 45 minutes and move on to painting.
