Zinsser B-I-N’s shellac-based formula is engineered to block even the toughest stains — including water marks, smoke damage, tannin bleed and ink — preventing them from bleeding through your topcoat.

Superior Adhesion
It adheres to difficult surfaces without the need for sanding or deglossing, saving time and preparation effort.

Seals Porous Substrates
By sealing porous materials, B-I-N enhances topcoat coverage and promotes smoother, more durable finishes with reduced paint usage.

Fast drying times accelerate project completion and allow earlier application of topcoats.
