Backer Rod for Expansion Joint Repair or Cracks
SealGreen Soft Type Backer Rod is a soft, pliable and non-gassing backup material that is inserted into a joint to control sealant depth. This creates a backstop to facilitate proper sealant tooling, yielding a quality bond breaker between the backup material and the sealant. ITP Soft Type Backer Rod can also be used as a temporary joint seal.
SealGreen Soft Type Backer Rod is suitable for specialty applications where standard backer rods are not appropriate. They are ideal for irregular joint applications, particularly where free flowing and self-leveling sealants are employed. SealGreen Soft Type Backer Rods can also be used in place of most standard backer rods, and are highly recommended for applications in which bubbling is a critical concern.
Backer rod needs to fit tightly with in the opening to remain in place and contain the self leveling caulk (45 SSL Caulk)
