Rust-Oleum Zinsser 290971 Bulls Eye 1-2-3 Water-Base Primer, Gray, 13 oz.

Zinsser Bulls-Eye 1-2-3 Gray Primer is a high-performance, water-based primer made for DIYers who want better coverage under rich or dark paint colors. It works indoors or outdoors and bonds to many common surfaces, including wood, drywall, plaster, concrete, masonry, aluminum, vinyl, steel, galvanized metal, PVC, glossy paint, varnish, laminate, and ceramic tile — often without sanding.

This primer helps block common stains, seals porous surfaces for a smoother finish, and dries fast so you can topcoat in about 1 hour. It is also mold and mildew resistant when dry, making it a practical choice for repainting walls, trim, siding, furniture, and other home improvement projects.
