Zinsser B-I-N Aqua is a white-pigmented, low-odour, water-based primer and sealer with knot-blocking properties.

It seals porosity to achieve a smooth finish and helps hide stains effectively. The formulation is designed for interior and exterior use, offering odor sealing for tannin, knots, sap streaks, and common staining sources, while maintaining practical handling with clean-up by soap and water.
