About Sealant Flexibility

Create-a-Color Caulk

Mix a small amount of water-based paint with this caulk to match the color of your surface. Caulk is non-sagging, so it 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 a sealant can sustain. This caulk is best suited to joints between similar materials that aren't exposed to wide temperature fluctuation.

Silicone Sealants

Made from silicone, these sealants are RTV (room-temperature vulcanizing). 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. Sealants that are good for joining dissimilar materials also work well in environments with wide temperature fluctuation.

Noncorrosive Silicone Sealants


Also known as neutral-cure sealants, these won't discolor copper, brass, and concrete. They’re non-sagging, so they won't drip from vertical and overhead surfaces. Made from silicone, 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. Sealants that are good for joining dissimilar materials also work well in environments with wide temperature fluctuation.
Sealants that cannot be sold to California exceed local regulatory limits on VOCs (volatile organic compounds).

All-Weather Application Structural Sealants











Apply these sealants in cold temperatures, on wet surfaces, and even through running water. They are structural sealants that combine the mechanical strength of an adhesive with excellent sealing properties and high flexibility. 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 good for use between dissimilar materials and in environments with wide temperature fluctuation.

Self-Leveling Oil- and Fuel-Resistant Sealants

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.

Oil- and Fuel-Resistant Sealants

These non-sagging sealants will not drip while hardening on vertical and overhead surfaces. They’re thicker than most non-sagging sealants, so they can be used in vertical joints up to 1/2" wide.
Elongation indicates flexibility—the higher the values are, the more sealants can stretch. These sealants are best suited to joints between similar materials that aren't exposed to wide temperature fluctuation.
Silicone sealants have excellent ozone resistance.
Sealants that cannot be sold to California exceed local regulatory limits on VOC (volatile organic compounds).

Structural Oil- and Fuel-Resistant Sealants


Impervious to the swelling effects of oils, fuels, and solvents, use this high-strength silicone sealant to assemble and repair fuel systems and tanks. Silicone forms a tough, rubbery, UV-resistant seal that remains flexible over time. It's non-sagging, so it won't drip from vertical and overhead surfaces. Also known as RTV (room-temperature vulcanizing).
Elongation and joint expansion/compression tolerance indicate flexibility—the higher the values are, the more joint movement sealants can sustain. This sealant is best suited to joints between similar materials that aren't exposed to wide temperature fluctuation.
