Standard Backer Rod-Cold is a round, flexible, continuous-length, non-absorbent, non-gassing, non-staining, and non-shrinking
material extruded from a closed cell polyolefin.
This easy to use material provides the correct sealant reservoir
configuration, controls depth and prevents run-out through the
bottom of joint as well as bottom side sealant adhesion. With either cold applied sealants, this product works exceptionally well.
• Non-gassing and heat resistant
• Provides correct form and depth for proper joint configurations
• Retains its original diameter

STANDARD BACKER ROD-COLD is used in large cracks or joints
in concrete or asphaltic pavement. It is installed with a smooth
blunt instrument that will insert the material without stretching
or puncturing it. Cold applied joint sealant applications can follow immediately.
•Roadways
•Parking Lots
•Airport Runways
• Works well with concrete or asphaltic surfaces
• Can be used equally well with hot or cold applied joint sealants
• Will not shrink, melt, evaporate or stain
• Retains its original diameter and is non-gassing
• Prevents run-out through voids or bottom of the joint
• Acts as a bond breaker to stop sealant adhesion to the bottom side of the joint
