Introducing Zinsser Cover Stain White Primer and Sealer, a dependable foundation for any painting project that demands serious stain blocking and a consistent topcoat. This 5-gallon white primer and sealer is designed to seize control of surface imperfections before you apply your finish coat, helping you achieve a smooth, uniform result from edge to edge.
Why this primer stands out
Cover Stain is formulated to address tough staining and porosity in a single, practical layer. Its white base is tintable, so you can tailor the undercoat to match or slightly underlay your chosen topcoat, reducing the number of coats needed and improving color fidelity. The result is fewer topcoat applications and a more even, long-lasting finish.
