Application and Use

Use between 40° and 100°F, in cool weather store at room temperature for 24 hours prior to use. For best performance apply Sikaflex when joint is at mid-point of its expansion and contraction. Apply sealant with steady pressure, forcing the sealant into the joint. Sealant should be applied to both sides of joint, use bond breaker tape to prevent bond at base of joint. If the depth of the joint exceeds 1/2" use of a backer rod is recommended. Tool sealant to ensure full contact with joint walls and remove trapped air. Do not tool with detergent or soap solutions. Tooling results in a correct bead shape, a neat joint and maximum adhesion.

Allow 1 week cure when using Sikaflex 1c SL in total water immersion situations.
