Prepare metal surfaces for powder coating. These primers create a base layer that bonds with your top coat to extend the life of your powder coating. Use a powder coating sprayer to apply these primers directly to unpainted metal and cure in an oven.

Epoxy primers are good general purpose primers for most metal.

Zinc/epoxy primers have excellent corrosion resistance, so they’re often used to protect metal that rusts easily, such as steel and cast iron.

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).

These primers stand up to marine exposure and salt spray. Use them to prepare your surface to extend the life of paint and coatings.

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 primers in a can with a brush or sprayer.

Product labeling requirements restrict sales to the listed areas.

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. Apply with a brush, roller, or sprayer.

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.

Epoxy primers have excellent abrasion resistance. The container size listed is the combined total of the three parts.
