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.

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.

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.

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

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.

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

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

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

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.

The textured finish matches concrete surfaces.

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.

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

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

To allow time to adjust and position parts, these epoxies remain workable for at least 90 minutes.

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