1 Inch Diameter Closed Cell Foam Backer Rod Gray Color In Crack Sealing

Backer rod comes in various sizes - 1/4", 7/8", 1 1/8", etc. You should chose the size that is just a bit bigger than the expansion joint or crack that you are trying to repair so that when the backer rod is inserted into the joint or crack that it creates a tight bond. You want it to fill the crack or joint so that when you apply the joint sealant caulk that the caulk stays above the backer rod and does not run under the backer rod and waste your caulk. Backer rod is an essential part of the package of materials you will need for expansion joint repair or expansion joint replacement.

Backer Rod is an ideal non-absorbent compressible backup material inserted into a joint to control sealant depth, create a backstop to allow proper sealant tooling, allows proper sealant of the joint surfaces, yields a proper bond between the back-up material and the sealant. It can also be used as a temporary joint seal.
