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. Install bond breaker tape or backer rod to prevent bond at base of joint.

   

Priming is not usually necessary. Substrates only require priming if testing indicates a need. Consult Sikaflex Primer Technical Data Sheet or Technical Service for additional information on priming.
