These primers convert rust into a layer of protection that prevents new rust from forming. Use them to prepare your surface to extend the life of paint and coatings.

Apply coatings in a can 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.

Polyurethane primers can be applied in environments with high humidity. They allow underlying moisture to escape while preventing additional water from getting in. Surface must be visibly dry and free of frost and ice. Apply with a brush, roller, or sprayer.

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

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.

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.

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.

Improve instant-bond adhesive performance on hard-to-bond slippery plastics. These primers cannot be sold to the regions listed because they exceed local regulatory limits on VOCs (volatile organic compounds).

Primers in brush-top bottles also include a spray head for easy dispensing.

To speed cure time on coated fasteners, aluminum, stainless steel, or titanium, apply these primers before using threadlocker or retaining compound. They also work with no-mix acrylic adhesives.

Primers in brush-top bottles also include a spray head for easy dispensing.

Prepare joints and surfaces to ensure proper sealant adhesion.

Primer for use on PVC plastic and TPO plastic is often used on roof joints.
