Zinsser Cover Stain High Hide Oil-Based Primer, 1 Gallon

Zinsser Cover Stain is a professional-grade, oil-based primer designed to block tough stains and provide exceptional hide on both interior and exterior surfaces. Its high-hide formula penetrates and seals porous substrates—such as bare wood, drywall, and plaster—while preventing tannin bleed, water marks, smoke and fire damage from showing through your topcoat. With excellent adhesion and enamel holdout, this low-VOC (100 g/L) primer creates a smooth matte base that accepts any finish coat for a flawless result.
