Performance & Benefits

Superior Stain Blocking
Zinsser B-I-N’s shellac formula permanently blocks tough stains — including tannin bleed, water marks and smoke residue — so they don’t bleed through your topcoat.

Excellent Adhesion
Achieves reliable grip on difficult surfaces such as glossy enamel, glazed tiles, PVC and non-sanded metal.

Seals Odours & Porous Substrates
Effective at sealing porous surfaces and blocking strong odours (e.g., smoke, pet smells) for improved topcoat performance.

Fast Drying
Dries quickly, accelerates project timelines and allows recoating within a short window.
