Application Method
The joint surface should be sound, clean, dry and free from grease, oil and contamination. Dust and debris should be removed by wire brushing, grinding and vacuuming. A backing rod or suitable bond breaker should be properly installed before applying the sealant.
The sealant sausage is placed into a hand-operated application gun and applied into the joint with slight excess for tooling. Immediately tool the sealant with a tooling knife to remove air pockets and ensure complete contact and adhesion.
