Fill cracks with these coatings to stop leaks and deaden sound. They resist rust, salt, and acid.

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.

Use this rubber tape to splice cable in high-voltage applications.

These patching compounds are the most flexible and watertight we offer. Developed for use on flashing, chimneys, and high-stress areas, they are highly vibration resistant.

With bright-colored dye and a fully equipped kit, you have everything you need to spot leaks in your HVAC system. These kits come with the correct amount of dye required for your system's size. Inject the dye into your system and scan it with the UV light—the dye is fluorescent, so it’s easy to spot most leaks right away. For small leaks, let the dye circulate for 24 hours and then inspect it again. Use the dye cleaner before you fix a leak. If the repair isn’t sufficient, you’ll be able to spot more dye.

Twice the sticking power of standard duct tape. With a thicker, rubber-based adhesive, this tape has a strong grip even on rough surfaces, such as wood, stucco, and cement. Also known as Gorilla Tape.

Clear enough to read through, this UV-resistant sealant allows optimal light transmission for use with solar cells and fiber optics. Apply it in cold temperatures, on wet surfaces, and even through running water. The sealant is non-sagging, so it won't drip from vertical and overhead surfaces. It cannot be sold to the regions listed due to local regulatory limits on VOC (volatile organic compounds).

Elongation indicates flexibility—the higher the value is, the more a sealant can stretch. This sealant is good for use between dissimilar materials and in environments with wide temperature fluctuation.

Fix roof leaks in cold and wet conditions. These sealants can even be applied underwater. They're non-sagging, so they won't drip from vertical and overhead surfaces. They are good for use in environments with wide temperature fluctuation.

Elongation indicates flexibility—the higher the value is, the more joint movement a sealant can sustain.

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

Apply these sealants on wet surfaces and in cold temperatures. They're non-sagging, so they won't drip from vertical and overhead surfaces.

Elongation and joint compression/expansion tolerance indicate flexibility—the higher the values are, the more joint movement sealants can sustain. These sealants are best suited to joints between similar materials that aren't exposed to wide temperature fluctuation.
