Zinsser 1 gal. Gray All-Purpose Primer is a high-performance, water-based primer engineered for interior and exterior residential, commercial, and industrial applications. It delivers exceptional stain-blocking resistance, adheres firmly to glossy surfaces without requiring sanding, and provides a uniform seal across a wide variety of substrates. Formulated to dry quickly, this primer works under and over any architectural oil or latex paint. It is ideal for use under rich or dark topcoat colors to improve hide and coverage, while the dried film resists mold and mildew growth.
