About Sealant Flexibility

Silicone Sealants

Made from silicone, these sealants are RTV (room-temperature vulcanizing).

Silicone Sealants with Material Certification

These sealants include a material certificate with traceable lot number, test report, and product shelf life.

Self-Leveling Silicone Sealants

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

Self-Leveling Silicone Sealants
with Material Certification

These sealants include a material certificate with traceable lot number, test report, and product shelf life.

Noncorrosive Silicone Sealants

Also known as neutral-cure sealants, these won't discolor copper, brass, and concrete.

Noncorrosive Silicone Sealants
with Material Certification

This sealant includes a material certificate with traceable lot number, test report, and product shelf life.

Sealants

Puncture-Resistant Sealants

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

Non-Hardening Caulk

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

Caulking Tape

Press this adhesive-backed plastic tape into place for an immediate light-duty seal.

All-Weather Application Structural Sealants

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

Structural Sealants

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

Structural Silicone Sealants

Structural Silicone Sealants with Material Certification

These sealants include a material certificate with traceable lot number, test report, and product shelf life.

Self-Leveling Oil- and Fuel-Resistant Sealants

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

Oil- and Fuel-Resistant Sealants

These non-sagging sealants will not drip while hardening on vertical and overhead surfaces.

Structural Oil- and Fuel-Resistant Sealants

Impervious to the swelling effects of oil, fuel, and solvents, use these high-strength sealants to assemble and repair fuel systems and tanks.

Submersible Sealants

These sealants are marine grade, so they stand up to water, corrosion from salt spray, mildew, and UV light.

Structural Submersible Sealants

The strongest submersible sealants we offer, these combine the mechanical strength of an adhesive with excellent sealing properties and high flexibility.

Concrete Joint Sealants

High-Strength Concrete Joint Sealants

These non-sagging sealants will not drip while hardening on vertical and overhead surfaces.

High-Strength Self-Leveling Concrete Joint Sealants

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

Concrete Joint Sealants

Seal joints and gaps in concrete.

Textured Concrete Joint Sealants

$Textured Concrete Joint Sealants$

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

Sealant Primers

Prepare joints and surfaces to ensure proper sealant adhesion.

Adhesives

Urethane Structural Adhesives

Urethane adhesives are the most flexible, so they bond dissimilar materials and damp vibration.

Construction Adhesives

Install building materials such as wood and drywall with these general purpose adhesives.

Concrete Crack Fillers

Fill cracks in horizontal, vertical, and overhead concrete surfaces.
