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.

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.

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

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

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

Roll out a fast fix for leaky roofs and gutters with these peel-and-stick rolls.

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

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.

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

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

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.

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

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

Thinner than non-sagging 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.

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

These sealants are non-sagging, so they won't drip from vertical and overhead surfaces.

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

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

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

With high shear strength and peel strength, these form the strongest bonds of our urethane adhesives.

Also known as Gorilla Glue, this glue expands to form stronger bonds than other glue.
