These surface fillers come in a pen for precision application. After applying, use the LED on the back of the pen to instantly cure.

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

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.

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

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.

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

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

Used on ceramic, concrete, and stone floor and wall tiles, grout consists of fine sand, masonry cement, and coloring.

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.

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.

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

The textured finish matches concrete surfaces.

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

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

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

These machinable epoxies are mixed with metal so they can be used to repair cracks and threaded holes.

Acrylics bond to the widest range of materials, especially plastics, and require the least amount of surface preparation.
