Stop slow-flowing and weeping leaks in concrete. These crack fillers begin to harden in three to five minutes to create a permanent fix that won't shrink.

Polyurethane fillers are thin to penetrate deep into cracks. When fully cured they create a seal that can withstand pressure of up to 2,000 psi. Apply with a standard caulk gun (sold separately). For especially large cracks, use a packer (sold separately) with a grease gun or a grout pump.

To use cement fillers, mix with water.

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. When fully cured they create a seal that can withstand pressure of up to 2,000 psi. Apply with a dispensing gun (sold separately). The size listed is the combined total of the two parts. A mixer nozzle is included.

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. Once cured, they withstand impact, abrasion, and chemicals. The size listed is the combined total of the two parts.

Polyurea compounds are ready for foot traffic in ten minutes and vehicle traffic in 30 minutes. They are self-leveling, but can be mixed with sand (not included) and applied with a trowel.

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. Use them to fix pitted, worn, and cracked concrete floors, stairs, and loading docks. Compounds resist salt water, oil, and chemicals, and stand up to forklift and truck traffic. The resin, hardener, and aggregate come in separate containers that can be mixed in the pail. Use the squeeze bottle for precision applications, such as in cracks and holes. The size listed is the combined total of the parts.

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

Mix cement surface fillers with water. They can be used to fill holes up to 7" deep. These quick-setting fillers are ready for foot traffic in just 30 minutes. Application time, after mixing, is 7 minutes.

Epoxy surface fillers are nonsagging. They resist oil, grease, water, alkalies, and chemicals. Application time, after mixing, is 1 hour. The size listed is the combined total of the two parts.

For use when thickness will be more than 2", concrete mixes consist of cement, sand, and gravel. Mix them with water. Concrete is ready for foot traffic when it reaches full strength.

For use when thickness will be less than 2", sand mixes consist of cement and sand. Mix them with water. They are ready for foot traffic at full strength.

Make a temporary repair to cracks in any flat roof. These patching compounds are a powder that forms a thick gel in minutes when poured directly into standing water and rain.

These patching compounds are the most flexible and watertight we offer. Developed for use on flashing, chimneys, and high-stress areas, they are highly vibration resistant.

Dispense compounds in a cartridge in a standard caulk gun (sold separately).

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

Repair holes and seal gaps in roofing and gutters. These patching compounds are durable and water resistant.

Apply acrylic compounds to dry surfaces. Apply asphalt compounds to wet or dry surfaces.

Reinforce hot- and cold-applied asphalt patching compounds and coatings with this flexible fabric.

Roll out a fast fix for leaky roofs and gutters with these peel-and-stick rolls. Backing is rubberized asphalt adhesive. Roll can be cut to size. Use primer (sold separately) for optimal adhesion.

Mix this two-part epoxy—a resin-aggregate blend and a pigmented hardener—to create a grout that resists chemicals, such as acids, alkalies, salt water, and common solvents and cleaners. Its lightweight formula makes this grout easy to spread. Use in horizontal or vertical joints—grout won’t sag or shrink. Apply with a grout float. It can be cleaned up with water when wet; it doesn’t require a sealer once it cures. The size listed is the combined total of the two parts.

Used on ceramic, concrete, and stone floor and wall tiles, grout consists of fine sand, masonry cement, and coloring. Apply with a grout float.

Mix cement grout with water.

Acrylic grout does not require mixing. It resists shrinking, cracking, and staining.

Used for brick, block, and stone laying as well as for repairing masonry, mortar mixes consist of fine sand and masonry cement. Mix it with water.

This putty-like glue cures into a pliable rubber. Use it to repair seals and cracks, or mold it into hooks and bumpers.

These machinable epoxies are mixed with metal so they can be used to repair cracks and threaded holes. The strongest and most weather- and chemical-resistant structural adhesives, epoxies work especially well on metals. For putty adhesives, slice off the required amount, then knead it together to form a moldable adhesive.

8267 is reinforced with steel, but won't rust.

Epoxies are the strongest and most weather- and chemical-resistant structural adhesives. They work especially well on metals. For putty adhesives, slice off the required amount, then knead it together to form a moldable adhesive.

For quick repairs, these epoxies begin to harden in 6 minutes or less. Epoxies are the strongest and most weather- and chemical-resistant structural adhesives.

The size listed is the combined total of the two parts.

50132 works especially well on plastics and composites.

To allow time to adjust and position parts, these epoxies remain workable for at least 90 minutes. The strongest and most weather- and chemical-resistant structural adhesives, epoxies work especially well on metals.

The size listed is the combined total of the two parts.

Urethane adhesives are the most flexible, so they bond dissimilar materials and damp vibration.

The size listed is the combined total of the two parts.
