Backer Rod

For joints greater than 1/4” a round, flexible length of extruded polyethylene backer rod can be used to create a surface backing. At the same time it insulates and acts as a bond breaker allowing the caulking material used to adhere better. Easy to install, backer rod will compress to fit a wider range of joint sizes. It allows for a faster cure of caulk. For indoor applications only. Open cell.
