Add long-term corrosion protection to uncoated or rusty metal surfaces. These paint primers prepare your surface to extend the life of paint and coatings. Apply with a brush, roller, or sprayer.

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.

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

Use these paint 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.

Get the power of a two-part epoxy paint primer in an easy-to-use aerosol can. These primers have excellent chemical and corrosion resistance. Spray them on uncoated or rusty metal to extend the life of paint and coatings. The two parts are contained in the same can; after activating, epoxy is usable for up to four days.

A high concentration of zinc gives these paint 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.

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 paint primers can be welded through without affecting the weld’s integrity.
