Epoxy Structural Adhesives

Epoxy Structural Adhesive Assortments

Assortments include eight different epoxies in 0.1-oz. packets to handle a variety of small jobs.

Metal-Reinforced Epoxy Structural Adhesives

These machinable epoxies are mixed with steel, but won’t rust, so they can be used to repair cracks and threaded holes.

Multi-Surface Fillers

Surface Fillers

These surface fillers can be used on vertical surfaces without sagging. They repair cracked, worn, and damaged surfaces.

Pourable Surface Fillers

Make castings and fill voids with these two-part pourable epoxies.

Aerosol Surface Fillers

Spray to fill in small dents, cracks, and scratches. These surface fillers build on themselves to cover minor surface imperfections.

Surface Filler Patches

Knead the epoxy-coated patch and resin together to make repairs to pipes, tanks, drums, and containers in the field.

Light-Activated Surface Fillers

Press these putty surface fillers in place to fill in holes, cracks, and dents. When exposed to sunlight or a UV lamp, they begin to harden immediately.

Light-Activated Surface Filler Patches

An easy way to make repairs in the field. Cut patches to size, peel off the backing, and press into place. Expose them to sunlight or a UV lamp and they begin to harden immediately.

Water-Resistant Surface Fillers

Mix these two-part epoxy surface fillers to create a strong repair in wet environments or underwater.

Water-Resistant Surface Filler Kits

Everything you need to repair cracked, worn, and damaged surfaces—even underwater.

Fuel-Resistant Surface Fillers

Also known as sloshing compounds, these surface fillers bond to rough, rusty surfaces in fuel tanks to repair leaks and prevent further corrosion.

Surface Fillers for Metal

Mix these two-part surface fillers together to repair leaks and cracks as well as to rebuild rough spots in metal.

High-Temperature Surface Fillers for Metal

Repair and rebuild metal surfaces that are exposed to heat. These surface fillers withstand temperatures over 450° F.

Impact-Resistant Surface Fillers for Metal

These rubber-filled epoxies have excellent wear and impact resistance. Use them to repair and rebuild surfaces such as pump liners, hoppers, and vibrating feeders.

Fine-Particle Abrasion-Resistant
Surface Fillers for Metal

For use in processing equipment that carries small particles less than 1/16" in diameter, these ceramic-filled epoxies rebuild and repair surfaces exposed to abrasion from particles, such as dust collectors, fan blades, and fan housings.

Large-Particle Abrasion-Resistant
Surface Fillers for Metal

For use in processing equipment that carries large particles 1/16" in diameter and larger, these ceramic-filled epoxies rebuild and repair surfaces exposed to abrasion from particles, such as pump housings, chute linings, and hoppers.

Chemical-Resistant Surface Fillers for Metal

Chemicals will not affect these two-part epoxies. They repair cracked, worn, and damaged surfaces.

Leak-Repair Patches for Metal

Seal leaks around small holes.

High-Pressure Leak-Repair Sticks for Metal

To stop leaks in metal tanks and equipment without draining the contents, heat the area with a heat gun or torch to melt the stick and form a permanent seal. The resulting patch can withstand pressure up to 600 psi.

Surface Fillers for Porcelain

Keep the surface of your porcelain fixtures looking like new.

Surface Fillers for Concrete

Large-Area Concrete Patching Compounds

Cover large sections of damaged concrete with these durable patching compounds. Made up of a resin, hardener, and aggregate, they cover more area than any of our other concrete patching compounds.

Concrete Patching Compounds

Patch concrete floors, stairs, and walls with these compounds.

Low-Temperature Concrete Patching Compounds

Use these two-part compounds to patch concrete floors, stairs, and walls in cold environments, such as freezers. At room temperature, they cure faster than any of our other concrete patching compounds.

Concrete Surface Fillers

Fill in and shape horizontal, vertical, and overhead concrete surfaces, such as steps and columns.

Chemical-Resistant Heavy-Traffic
Concrete Leveling Compounds

These leveling compounds stand up to acid and chemical spills, making them a good choice for corrosive environments. They also withstand steel wheels and heavy impacts.

Concrete Leveling Compounds

Repair sidewalks and factory floors in areas with heavy pedestrian traffic. They can also be used to fill minor depressions and cracks.

Heavy-Traffic Concrete Leveling Compounds

Not only do these leveling compounds withstand severe abrasion, wear, and impact, they also stand up to steel wheels and heavy blows without cracking.

Sand Mixes

For use when thickness will be less than 2", sand mixes consist of cement and sand.

Concrete Mixes

For use when thickness will be more than 2", concrete mixes consist of cement, sand, and gravel.

Self-Leveling Deep-Crack Concrete Fillers

Fill cracks up to 4" deep on horizontal surfaces, such as floors and sidewalks.

Deep-Crack Concrete Fillers

Fill cracks up to 10" deep on vertical and overhead surfaces.

Concrete Crack Fillers

Fill cracks in horizontal, vertical, and overhead concrete surfaces.

Leak-Stopping Concrete Crack Fillers

Stop slow-flowing and weeping leaks in concrete. Also known as hydraulic cement, these crack fillers begin to harden in three to five minutes to create a permanent fix that won't shrink.

High-Flow Leak-Stopping Concrete Crack Fillers

Stop active leaks of up to 50 gallons per minute in concrete, brick, and stone. These crack fillers begin to harden within seconds to create a permanent fix that won't shrink.

Surface Fillers for Plastic

Use these two-part fillers to rebuild cracked or worn plastic surfaces.

Surface Fillers for Wood

Wood Crack Fillers

Press these putty-like fillers into cracks in wood up to 1/8" wide.

Wood Surface Fillers

Fix damaged wood or build up and replace missing wood.

Surface Fillers for Drywall and Ceilings

Ceiling Texture Compounds

Spray these compounds onto ceilings to create a popcorn texture that covers stains, patches, and chips. The nozzle is upright for easy application.

Drywall Texture Compounds

Spray these compounds onto drywall to create an orange-peel texture that covers stains, patches, and chips. The nozzle adjusts from a light to heavy spray.

Drywall Joint Compounds

Also known as drywall mud, these joint compounds are ready to use. Apply with drywall tape over seams for a finished appearance.

Spackling Compounds

Fill and conceal small cracks, nail holes, and blemishes. Compounds are ready to use.

Drywall Crack Fillers

Fix cracks in drywall and stop them from spreading. Place the included fabric over wall cracks and cover with the acrylic paste. This results in a flexible, nonshrinking repair that prevents cracks from reappearing as the building continues to settle.

Plaster Surface Fillers

Also known as Plaster of Paris, these fillers conceal small cracks, nail holes, and blemishes. Mix with water.
