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 active leaks of up to 50 gallons per minute in concrete, brick, and stone. These crack fillers begin to harden within seconds 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.

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

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.

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

This putty-like glue cures into a pliable rubber. Use it to repair seals and cracks, or mold it into hooks and bumpers.

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

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

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.

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

Resistant to mold and mildew, these sealants are well suited to high-humidity environments.

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

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

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.
