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

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.

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.

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

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

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 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.

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

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.

Also known as neutral-cure sealants, these won't discolor copper, brass, and concrete.

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

These structural sealants combine the mechanical strength of an adhesive with excellent sealing properties and high flexibility.

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.
