Application

Application Information

Ambient Air Temperature

40-100 °F. Sealant should be installed when joint is at mid-range of its anticipated movement.

Substrate Temperature

40-100 °F. Sealant should be installed when joint is at mid-range of its anticipated movement.

Application Steps

SUBSTRATE PREPARATION

Clean all surfaces. Joint walls must be sound, clean,dry, frost-free, and free of oil and grease. Curing compound residues and any other foreign matter must be thoroughly removed. A mechanically roughened surface will also enhance bond. Sikaflex®-1c SL can be applied in green concrete after the concrete has cured for a minimum of 24 hours at 75°F. (23°C). For green concrete applications in control joints the concrete must be cut 8 hours (min.) prior to sealant installation and in expansion joint the forms must be removed 6 hours (min.) prior to sealant installation. For wet concrete applications all excess or standing water must be displaced and concrete must then dry for a minimum of 60 min prior to sealant installation. Install bond breaker tape or backer rod to prevent bond at base of joint. If sealant will be used in immersion service then priming is required - when using primer, green and damp concrete conditions should be avoided.
