Unlike standard silicone sealants, this silicone sealant can be painted. It’s non-sagging, so it won't drip from vertical and overhead surfaces. This sealant is also known as 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 good for use between dissimilar materials and in environments with wide temperature fluctuation.

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).

These structural sealants combine the mechanical strength of an adhesive with excellent sealing properties and high flexibility. They’re non-sagging, so they won't drip from vertical and overhead surfaces. Made from silicone, these sealants are RTV (room-temperature vulcanizing). They cannot be sold to California due to local regulatory limits on VOC (volatile organic compounds).

Elongation indicates flexibility—the higher the values are, the more sealants can stretch. These sealants are good for use between dissimilar materials and in environments with wide temperature fluctuation.

Press this adhesive-backed plastic tape into place for an immediate light-duty seal. It has a score line for easy installation in a corner.

Also known as thumb-grade caulk, this forms a non-hardening, moisture-resistant seal that remains pliable.

Butyl mastic has a clay-like consistency.

These non-sagging sealants will not drip while hardening on vertical and overhead surfaces. They’re marine grade, so they stand up to water, corrosion from salt spray, mildew, and UV light.

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.

The strongest submersible sealants we offer, these combine the mechanical strength of an adhesive with excellent sealing properties and high flexibility. They’re marine grade, so they stand up to water, corrosion from salt spray, mildew, and UV light. Sealants are non-sagging, so they won't drip from vertical and overhead surfaces.

Elongation indicates flexibility—the higher the values are, the more sealants can stretch. These sealants are good for use between dissimilar materials and in environments with wide temperature fluctuation. For high-wear applications, choose a harder sealant for the most abrasion resistance.

Certificates with a traceable lot number and product shelf life are available for these products. Download certificates from ACTIVITY after your order ships.

Prepare joints and surfaces to ensure proper sealant adhesion.

Primer for use on PVC plastic and TPO plastic is often used on roof joints.

These sealants don't degrade in sunlight. Also known as glazing compounds, use these sealants to install glass in framing. They’re non-sagging, so they won't drip from vertical and overhead surfaces. Made from silicone, these sealants are RTV (room-temperature vulcanizing).

Elongation and joint compression/expansion tolerance indicate flexibility. For joints between dissimilar materials and in environments with wide temperature fluctuation, choose a sealant with a higher elongation or joint compression/expansion tolerance.

Use these two-part compounds to patch concrete floors, stairs, and walls in cold environments, such as freezers. At room temperature, they cure faster than any of our other concrete patching compounds. Once cured, they withstand impact, abrasion, and chemicals. The size listed is the combined total of the two parts.

Epoxy compounds are ready for foot traffic in ten minutes and vehicle traffic in two hours. Urethane compounds are ready for foot traffic in five minutes and vehicle traffic in ten minutes. Both can be applied with a trowel when mixed with the included aggregate or used as a self-leveling compound when used alone. Mix in the included pail.

Also known as Gorilla Glue, this glue expands to form stronger bonds than other glue. It is waterproof, paintable, stainable, and sandable at full strength.
