Use these primers on metal surfaces in enclosed occupied areas, such as hospitals, schools, and offices. They have excellent resistance to moisture and corrosion and bond well to metal to extend the life of paint and coatings. Apply with a brush, roller, or sprayer.

A high concentration of zinc gives these primers excellent corrosion resistance for protecting steel—when exposed to moisture and chemicals, the zinc rusts before the underlying steel can. They’re often used with structural steel to prepare the surface for paint while forming a protective layer.

Epoxy primers have excellent abrasion resistance. Apply with a brush or roller. The container size listed is the combined total of the three parts.

Protect steel and iron parts from corrosion without having to remove the primer before welding them together. Often used on structural steel in demanding environments, these primers can be welded through without affecting the weld’s integrity. Apply with a brush or sprayer.

Use these primers on your surface before antislip coatings to maximize longevity. They do not contain grit. Apply with a brush, roller, or sprayer. The size listed is the combined total of the two parts. They cannot be sold to the regions listed because they exceed local regulatory limits on VOCs (volatile organic compounds).

Extend the life of your paint and coatings on damage-prone metal surfaces. When scratched or worn, these primers release small capsules of uncured primer to provide continued corrosion resistance. Apply with a brush, roller, or sprayer. The size listed is the combined total of the two parts.

These primers fill surface cracks and are sandable for a smooth basecoat. Use them to prepare your surface to extend the life of paint and coatings. Choose gray for light-color topcoats; red for medium-color topcoats; and black for dark topcoats.

Primers that cannot be sold to California exceed local regulatory limits on VOC (volatile organic compounds).

Use these primers in enclosed occupied areas, such as hospitals, schools, and offices. They cover stains and prepare your surface, extending the life of paint and coatings. Apply with a brush, roller, or sprayer.

Acrylic primer prepares surfaces for paint.

Prepare metal, wood, and concrete for paint. Primers adhere to underlying surfaces to create a base layer that bonds well with paint for a long-lasting finish.

Apply primer in a one-gallon can with a brush, roller, or sprayer. Use red primer on rusty and abrasive-blasted steel. Follow with a coat of gray primer. Use gray primer on galvanized steel and on all other surfaces.

Primers that cannot be sold to the regions listed exceed local regulatory limits on VOC (volatile organic compounds).

Cover stains from smoke, water, and ink to prevent them from bleeding through your topcoat, extending the life of paint and coatings.

For use in damp areas, these primers dry to a finish that prevents future stains caused by mold and mildew. Use them to cover existing stains and to extend the life of paint and coatings. Apply with a brush or roller.

Increase paint’s ability to bond to hard, smooth surfaces, such as tile and metal.

Acrylic primer is often used on previously painted hard, slick, or glossy surfaces. Use it indoors or out. Apply with a brush, roller, or sprayer.

Epoxy primer is designed for use on floors to improve the longevity of paint and coatings. This low-odor primer can be used in enclosed occupied areas. For indoor use only. The size listed is the combined total of the two parts. Apply with a brush or roller.

Use this zero-VOC primer on drywall in enclosed occupied areas, such as hospitals, schools, and offices, to extend the life of paint. Apply with a brush, roller, or sprayer.

These primers have excellent adhesion to plastic. Use them to prepare your surface to extend the life of paint and coatings.

Also known as block filler, these primers fill cracks and smooth surface irregularities. Use them to prepare concrete floors to extend the life of paint and coatings. Apply with a brush, roller, or sprayer.

These thin primers penetrate deeply into concrete floors to create a hard surface that can then be coated with any urethane or epoxy coating. Primers resist abrasion and chemicals, such as mild acids, alkalies, salt, and fuel. Apply with a roller. The size listed is the combined total of the two parts.

Use these primers on concrete floors before antislip coatings to maximize longevity. They do not contain grit. Apply with a brush or roller. The size listed is the combined total of the two parts.

Make your surface magnetic with this paint. It’s designed for use as an undercoat—cover with water-based paint. Apply with a brush, roller, or sprayer.
