Sealants

These sealants are non-sagging, so they won't drip from vertical and overhead surfaces.

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

All-Weather Application Structural Sealants


Cartridge	Limestone

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.

High-Strength Self-Leveling Concrete Joint Sealants

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.

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.

Sikaflex—When Sika Sikaflex Polyurethane requires a primer, for best results use Primer 260 on metal and Primer 449 on plastic and rubber.

Silicone Rubber—Silicone rubber sealant is RTV (room-temperature vulcanizing).

Structural Glass Sealants

Sausage Pack

Make seals that support glass under heavy loads in equipment and buildings. These sealants are also known as glazing compounds. They’re non-sagging, so they won't drip from vertical and overhead surfaces. Made from silicone rubber, sealants are RTV (room-temperature vulcanizing).

Joint compression/expansion tolerance indicates flexibility—the higher the value is, the more joint movement a sealant can sustain.
