Backer Rod is a closed cell, 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

Our backer rod is a round, 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.

SPECIFIC USES

  • Glazing installations
  • Window and door applications
  • Expansion joints
  • Curtain wall joints
  • Partitions
  • Log construction
  • Pavement joints and repairs
  • Pre-cast units and copings

LIMITATIONS

Backer Rod 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.

INSTALLATION

Joint or opening must be free of all contaminants, loose materials, dry and free of frost. Select correct rod size for joint width. With a blunt instrument or roller, seat Backer Rod to depth recommended by sealant manufacturer.
