At times, an isolation joint may need a bond breaker between the joint filler and the joint sealant to ensure that both have free movement and don’t tear. Without this bond breaker, the two materials may form a molecular bond. Bond breakerscan either be either membrane-forming or non-memb...
However, a backer rod or bond breaker tape should be installed over the joint filler to prevent the sealant from bonding to the filler. SIZE/PACKAGING PER SKIDWidth Thickness 3/8" 1/2" 3/4" 1" 3" 16000' 12000' 8000' 6400' 4" 12000' 9000' 6000' 4800' 5" 9000' 6750' ...
