Zinsser Cover Stain Primers (High Performance)

Zinsser Cover Stain Oil-Based Primer is a trusted, all-purpose solution for sealing surfaces and blocking stains in both interior and exterior environments. Known for its high hiding power and fast dry time, this primer is ideal for restoration projects involving smoke, fire, water, or nicotine damage. It penetrates and seals bare wood, blocks tannin bleed from cedar and redwood, and adheres to a wide range of surfaces including drywall, plaster, masonry, metal, vinyl, and glossy finishes—without the need for sanding. Cover Stain dries to the touch in just 30 minutes and can be recoated in one hour, making it a time-saving choice for professionals and DIYers alike. It’s also suitable for hard-to-paint objects like outdoor furniture, posts, railings, and arts and crafts. The primer forms a smooth, sandable film that improves topcoat coverage and sheen consistency. It can be tinted to off-white or pastel shades to enhance hiding power. Application is easy with a brush, roller, pad, or sprayer, and cleanup is done with paint thinner or mineral spirits. For best results, spot-prime heavy stains and prime the entire surface before painting. Whether you're sealing porous surfaces or blocking stubborn stains, Cover Stain delivers reliable performance and long-lasting results across a variety of substrates.
