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 with a brush 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 size listed is the combined total of the two 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.

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.

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.

Use primer in an aerosol can for quick jobs and touch-ups.

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.

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.

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.

Epoxy primer prepares surfaces for epoxy coatings. The size listed is the combined total of the two parts.

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

Acrylic primer can be applied directly to metal. It resists corrosion, mold, and mildew. Apply with a brush, pad, roller, or sprayer.

Shellac primer seals in odors and has the best stain-blocking ability of any of the primers we offer. It also seals knots and sap in wood. Apply with a brush, roller, or sprayer.

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.

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

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.

Prevent threaded fasteners from loosening due to shock and vibration. These threadlockers begin to harden once coated surfaces are threaded together and exposure to air is blocked. Primer (sold separately) cleans the surface and decreases the time to reach full strength. It is recommended when working with aluminum, stainless steel, and titanium; black-oxide finishes; and cadmium and zinc coatings.

Threadlockers with medium locking strength require a hand tool to unthread.

Threadlockers with high locking strength require both heat and a hand tool to unthread.

To withstand demanding, high-vibration applications such as motor and pump housings, these threadlockers have high breakaway torque. They begin to harden once coated surfaces are threaded together and exposure to air is blocked.

Primer (sold separately) cleans the surface and decreases the time to reach full strength. It is recommended when working with aluminum, stainless steel, and titanium; black-oxide finishes, and cadmium and zinc coatings.

Apply these threadlockers on fasteners that are already installed—their thin consistency allows them to flow into small gaps. They begin to harden once coated surfaces are threaded together and exposure to air is blocked.

Threadlockers with medium locking strength require a hand tool to unthread.

Fill gaps up to 0.01" to secure unthreaded cylindrical metal parts such as shafts, bearings, and press-fit assemblies. These retaining compounds begin to harden once coated surfaces are pressed together, blocking exposure to air.

Primer (sold separately) cleans the surface and decreases the time to reach full strength. It is recommended when working with aluminum, stainless steel, and titanium; black-oxide finishes, and cadmium and zinc coatings.

These threadlockers give a secure hold, but can be easily adjusted with hand tools. They can be removed without damaging countersunk fasteners, set screws, and other small fasteners. These threadlockers begin to harden once coated surfaces are threaded together and exposure to air is blocked.

Primer (sold separately) cleans the surface and decreases the time to reach full strength. It is recommended when working with aluminum, stainless steel, and titanium; black-oxide finishes, and cadmium and zinc coatings.

Threadlockers begin to harden once coated surfaces are threaded together and exposure to air is blocked.

Prepare joints and surfaces to ensure proper sealant adhesion.

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