Zinsser 3501 Cover-stain Oil-based Primer, White, 1 Gallon

Zinsser Cover-Stain is an all-purpose oil-based primer and sealer designed for both interior and exterior surfaces. This whole-house primer is a favorite with professionals for its ability to block stains, hide dark colors, and prevent tannin bleed on bare wood such as cedar and redwood. It penetrates and seals exterior wood while providing excellent adhesion and flexibility for a durable foundation before topcoating.

The formula hides most common household stains from nicotine, fire, smoke, and water damage. The oil-based composition sticks to all surfaces and sands easily for a smooth finish. Fast-drying coverage allows recoating in less than one hour, reducing project timelines and making it an efficient choice for both interior and exterior work.
