Zinsser White Interior Water Base Prime & Seal Primer, 1 Gallon is a specially developed general-purpose primer designed for professional painters. This high-performance primer quick drying, excellent hiding power, and universal adhesion, making it for all interior surfaces. Its heavy-bodied formula flows smoothly and can be applied easily with a brush, roller, or airless spray. Compatible with all architectural topcoats, it levels evenly to a flat, easy-to-sand finish that provides an i base for both latex and oil-based paints. This primer effectively blocks bright colors and patterns, unifies porosity in remodeled areas, and serves as a great enamel undercoat for new wood by resisting grain-raise and sanding easily within just one hour. It is suitable for priming and sealing interior walls, ceilings, doors, trim, and paneling on new or previously painted drywall, wood, cured plaster, metal doors, and galvanized metal. Each gallon covers approximately 400 square feet depending on surface porosity. The white primer is also tintable with up to 2 ounces of universal colorant per gallon. Cleanup is simple with warm water and liquid detergent. Model Number: 01801
