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.

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

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 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).

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.

Primers cannot be sold to the listed regions due to regulatory limits on VOCs (volatile organic compounds).

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.

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. They come in an aerosol can, so they’re good for quick jobs and touch-ups.

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.

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.

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.

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.

These primers have excellent adhesion to plastic. Use them to prepare your surface to extend the life of paint and coatings.

These thin primers penetrate deeply into concrete floors to create a hard surface that can then be coated with any urethane or epoxy coating. Primers resist abrasion and chemicals, such as mild acids, alkalies, salt, and fuel. Apply with a roller. The size listed is the combined total of the two parts.

Also known as block filler, these primers fill cracks and smooth surface irregularities. Use them to prepare concrete floors to extend the life of paint and coatings. Apply with a brush, roller, or sprayer.

Use this zero-VOC primer on drywall in enclosed occupied areas, such as hospitals, schools, and offices, to extend the life of paint. Apply with a brush, roller, or sprayer.

Prepare PVC and CPVC pipe for bonding.

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.

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.

Certificates with a traceable lot number and product shelf life are available for these products. Download certificates from ORDER HISTORY after your order ships.

Use these primers with structural epoxies, acrylics, and urethanes to promote bonding to EPDM rubber, polyolefin, and thermoplastic elastomers. They cannot be sold to the regions listed due to local regulatory limits on VOC (volatile organic compounds).

Shorten the time it takes instant-bond adhesives to reach full strength. Apply these accelerators before bonding with instant-bond adhesives for strength, or after bonding to keep adhesive from turning cloudy.

Bottles of Scotch-Weld 87937, 712, 7109, and 7113 include both a brush and spray head for easy dispensing.

Scotch-Weld 87937 also works as a primer on porous materials.

7109 is nonflammable.

7113 helps bond coils to ferrite cores in electromagnets.

QFS16 does not contain ODCs (ozone-depleting chemicals). It can be used on porous materials.

Accelerators that cannot be sold to the regions listed exceed local regulatory limits on VOC (volatile organic compounds).

Create strong, leakproof joints between unthreaded pipe and fittings. Cleaner and primer (sold separately) are recommended to prepare pipe for adhesion.

Cement for CPVC plastic and for PVC plastic meets NSF/ANSI 61 safety standards for use on drinking water systems. It is also suitable for drain, waste, and vent pipes.

Prepare joints and surfaces to ensure proper sealant adhesion.

3M P592 primer cannot be sold to the listed regions due to volatile organic compound regulations.

Clean surfaces before applying sealant to promote bonding. Cleaners cannot be sold to the listed regions due to regulatory limits on VOCs (volatile organic compounds).
