Structural Sealants
 |  |
Cartridge | Sausage Pack |
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.
Elongation and joint compression/expansion tolerance indicate flexibility—the higher the values are, the more joint movement sealants can sustain. 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.

High-Strength Concrete Joint Sealants
|
Cartridge |
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.

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.
