Its non-absorbent structure can make it good for long-term outdoor applications like driveways and foundations. As a good foam rope and caulk backer rod, it serves as the good backing material for sealants, ensuring a neat, professional finish.
Application is straightforward: measure your need, cut the foam rod to size, and insert it using our recommended backer rod insertion tool (or a simple tool) for deep or narrow cracks. This backing rod compresses easily to fill irregular shapes, creating a tight, lasting seal. Use it as a caulk cord weatherseal for doors and windows to block drafts, as a foam dowel for crafts, or for industrial noise and vibration damping.
