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

These patching compounds are the most flexible and watertight we offer.

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

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

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.

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

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

Mix this two-part epoxy—a resin-aggregate blend and a pigmented hardener—to create a grout that resists chemicals and doesn't require sealing. Use on ceramic, concrete, and stone floor and wall tiles.

Epoxies are the strongest and most weather- and chemical-resistant structural adhesives. They work especially well on metals.

For quick repairs, these epoxies begin to harden in 6 minutes or less.

Also known as thumb-grade caulk, this forms a non-hardening, moisture-resistant seal that remains pliable.

Mix a small amount of water-based paint with this caulk to match the color of your surface.

Resistant to mold and mildew, these sealants are well suited to high-humidity environments.

Meeting requirements for semiconductor, biomedical, and electronics clean rooms, these sealants won’t contaminate air and surfaces.

A combination of hardness and surface tension makes these sealants resistant to punctures, cuts, and abrasion.

Apply these sealants in cold temperatures, on wet surfaces, and even through running water.

With chemical and metal additives that are picked up by X-ray machines and metal detectors, these sealants are designed to help you comply with Hazard Analysis and Critical Control Point (HACCP) programs in food-processing facilities.

Thinner than non-sag sealants, these flow easily into cracks and have a smooth finish.

These non-sagging sealants will not drip while hardening on vertical and overhead surfaces.
