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

Seal joints and gaps in concrete.

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.

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.

Clear enough to read through, this UV-resistant sealant allows optimal light transmission for use with solar cells and fiber optics.

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

Tested to meet ASTM E595, a standard used by NASA, these sealants fill joints and seams while releasing almost no volatile emissions that could damage sensitive electronics, even in a vacuum.

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.

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

Fix roof leaks in cold and wet conditions. These sealants can even be applied underwater.

Pour these ready-to-use fillers in cracks up to ½" wide and ¼" deep on horizontal surfaces to make fast, light duty repairs.

Fill cracks up to 4" deep on horizontal surfaces, such as floors and sidewalks.

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 and stairs in cold environments, such as freezers. At room temperature, they cure faster than any of our other concrete patching compounds.

Patch concrete floors and stairs with these compounds.

These leveling compounds stand up to acid and chemical spills, making them a good choice for corrosive environments. They also withstand steel wheels and heavy impacts.

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

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.

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

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.

Able to withstand temperatures up to 2300° F, these ceramic surface fillers are often used as thermal insulation on brick, mortar, burner blocks, furnace holders, and thermocouples.

An easy way to make repairs in the field. Cut patches to size, peel off the backing, and press into place. Expose them to sunlight or a UV lamp and they begin to harden immediately.
