Basic Use: ITP Standard Backer Rod is an ideal compressible and non-absorbent backup material that is inserted into a joint to control sealant depth. This creates a backstop to facilitate accurate sealant tooling and proper sealant wetting of the joint surfaces, yielding a quality bond breaker between the backup material and the sealant. ITP Standard Backer Rod can also be used as a temporary joint seal.
Specific Uses: ITP Standard Backer Rod is suitable for glazing installations, window and door applications, expansion joints, curtain wall joints, partitions, log construction, pavement jobs, repairs, precast units and copings.
Compatibility: ITP Standard Backer Rod is compatible with butyl, polysulfide, acrylic polyurethane, silicone and most other cold applied sealant compositions.
