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.

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.

Cut rope to the length you need, pack it in cracks up to 1" wide, and heat with a propane torch (not included). Rope is self-leveling.

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. When fully cured they create a seal that can withstand pressure of up to 2,000 psi. Apply with a dispensing gun (sold separately). The size listed is the combined total of the two parts. A mixer nozzle is included.

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

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

These crack fillers come in an easy-to-pour jug for filling cracks in asphalt up to _1/2" wide. They’re ready for traffic in 2 to 5 days.

Keep out the elements by sealing roof joints. Thinner than non-sagging sealants, these flow easily into cracks and have a smooth finish. They're good for use in environments with wide temperature fluctuation.

The textured finish matches concrete surfaces. These sealants are 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.

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

Seal concrete joints in high-traffic areas—these sealants stand up to heavy wear and tear, such as steel wheel traffic. They're non-sagging, so they won't drip from vertical and overhead surfaces. Made from silicone rubber, sealants are RTV (room-temperature vulcanizing).

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. For high-wear applications, choose a harder sealant for the most abrasion resistance.

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

Elongation and joint expansion/compression tolerance indicate flexibility. For joints between dissimilar materials and in environments with wide temperature fluctuation, choose a sealant with a higher elongation or joint expansion/compression tolerance. For high-wear applications, choose a harder sealant for the most abrasion resistance.

Stop slow-flowing and weeping leaks in concrete. These crack fillers begin to harden in three to five minutes to create a permanent fix that won't shrink.

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.

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.

Seal concrete joints in high-traffic locations—these sealants stand up to heavy wear and tear, such as steel wheel traffic. Thinner than non-sagging sealants, these flow easily into cracks and have a smooth finish.

Keep out the elements by sealing roof joints. These sealants are non-sagging, so they won't drip from vertical and overhead surfaces. They are good for use in environments with wide temperature fluctuation.

Roll out a fast fix for leaky roofs and gutters with these peel-and-stick rolls. Backing is rubberized asphalt adhesive. Roll can be cut to size.
