Improve instant-bond adhesive performance on hard-to-bond slippery plastics.

Prepare joints and surfaces to ensure proper sealant adhesion.

Prepare metal, wood, and concrete for paint. Paint primers adhere to underlying surfaces to create a base layer that bonds well with paint for a long-lasting finish. They come in an aerosol can, so they’re good for quick jobs and touch-ups.

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.

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.

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.

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.

These paint 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.

Use these paint 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.

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.

Spray these adhesive primers onto a mounting surface to quickly and smoothly apply signs, labels, and protective films. These primers float adhesive-backed sheets above a surface until you press them down, giving you time to position the sheet and remove any wrinkles. Since the sheet doesn’t stick right away, you can apply large sheets without needing a second pair of hands. These primers also work with non-adhesive films. Even in hot or cold temperatures, your sheet will stay put.

Clean the mounting surface with adhesive primer before applying a film, so no residue is trapped underneath. Use a smoothing tool (sold separately) to squeeze out air bubbles and excess fluid. Drying time depends on application—most decals and films will dry within 90 seconds, but 3D printer sheets should dry for 24 hours before printing.

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

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

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.

Use these paint 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.

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.
