Soft Type Backer Rod

Backer rods are round, flexible lengths of foam that are used as a “backing” in joints or cracks to help control the amount of sealant used or the depth of the sealant in the gap. Available in widths from 3/4″ to 2″. Soft Type backer rod is a pliable bi-cellular PE foam material used for filling irregular joints. It is chemically inert and will resist oil, gasoline and most other solvents. Its unique construction is highly compressible, but has a closed cell outer skin to resist moisture. Particularly suited for specialty applications where standard backer rods are not appropriate and for irregular joint applications particularly where self-leveling, flowable sealants are employed.
