Backer Rod (round) is extruded, closed-cell polyethylene rod/rope that is used in cracks, checks and gaps before filling them with sealants such as, Energy Seal caulk, Check Mate 2 or Perma-Chink. Backer Rod provides a firm yet flexible surface on which to apply sealants. The sealant will adhere to the log above and the log below but float over the Backer Rod which is a natural releasing agent. The Backer Rod allows the sealant to expand and contract as the log moves due to natural settling and weather changes.
Uses: Caulk joints should be no more than 3/8” thick and Backer Rod provides a way to fill a deep crevice or gap while maintaining the proper sealant thickness for maximum performance. Backer Rod should also be used in checks / cracks over 1/4” wide before applying Check Mate 2.
