PRODUCT DESCRIPTION
Backer Rod Closed-Cell is a resilient, polyethylene backer rod used as a backup material for construction joints and applications that require sealants. It performs as a depth control for most known cold-applied sealants. Sealants will not adhere to it; no bond breaker is required.

COMPOSITION AND MATERIALS
Backer Rod is a round, black, resilient, extruded closed-cell polyethylene backer rod with a water-resistant outer skin. It is compatible with most known cold-applied sealants such as urethane, silicone, acrylic, butyl, polysulfides, latex, and chinking sealants.

Backer Rod is chemically inert and will resist gasoline, oil, and most solvents. The product will not stain or adhere to sealants.

SPECIFIC USES INCLUDE

• Expansion joints
• Highway joints
• Curtain wall joints
• Pavement joints and repairs
• Partitions
• Window and door applications
• Precast concrete coping
• Glazing
• Log home chinking
• Parking Decks

LIMITATIONS

Backer Rod Closed-Cells should be installed with a roller or blunt, flat-sided tool. Please follow sealant manufacturer specifications for recommended sealant width and depth ratio. For best results, do not puncture, fold or overly stretch the product. The product is made with a water-resistant outer skin, therefore where moisture resistance is important, care should be taken not to puncture this outer surface skin.
