Zinsser B-I-N Primer

Zinsser B-I-N Primer is a highly effective shellac-based primer, sealer and stain killer. Apply BIN primer and undercoat to interior & exterior multi-surface, using a brush, to prepare the surface for painting. It permanently blocks odours and stains and takes just 45 minutes to dry. Ideal for spot priming of exterior surfaces.

B-I-N offers unparalleled adhesion to glossy surfaces – including glass – without the need for scuff sanding and blocks stubborn and persistent stains. The high adhesion shellac formula seals porous surfaces with excellent enamel holdout, even sealing bleeding knots and sap streaks.
