A Permanent Seal
3M™ Strip-Calk never hardens or becomes brittle, so seams stay smooth and gaps stay filled. It is also non-shrinking, which makes it excellent as a sealer for plugging holes and preventing noise and moisture penetration. You won’t have to reapply, and you’ll never have to perform rework because the sealer shrank, dried up and stopped working.

It’s great as a seam and gap filler as well as a sealer for noise and moisture, even in high-temperature spaces.
