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.

Sand fillers are also known as hydraulic cement. 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.

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.

Epoxy compounds are ready for foot traffic in ten minutes and vehicle traffic in two hours. Urethane compounds are ready for foot traffic in five minutes and vehicle traffic in ten minutes. Both can be applied with a trowel when mixed with the included aggregate or used as a self-leveling compound when used alone. Mix in the included pail.

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.

Give new life to damaged and worn concrete floors. These leveling compounds also fill minor depressions and cracks. Apply with a trowel.

Cement compounds are ready for foot traffic in 3 to 4 hours. Add water and mix before applying.

Epoxy compounds resist abrasion for use in high-traffic areas. They’re ready for foot traffic in 8 hours. The resin and hardener are in separate containers that can be mixed in the pail. The size listed is the combined total of the two parts.

These leveling compounds stand up to acid and chemical spills, making them a good choice for corrosive environments. They also withstand steel-wheel traffic and heavy impact. Apply with a trowel. They're ready for foot traffic in 12 hours. The resin and hardener are in separate containers that can be mixed in the pail. The size listed is the combined total of the two parts.

Not only do these leveling compounds withstand severe abrasion, wear, and impact, they stand up to heavy steel-wheel traffic and heavy blows without cracking. Apply with a trowel. They're ready for foot traffic in 12 hours. The resin and hardener are in separate containers that can be mixed in the pail. The size listed is the combined total of the two parts.

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.

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.

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