Inert and does not adhere to sealants
Meets all requirements of the 1990 Clean Air Act
Closed cell backer rods are designed to limit the depth of sealants, help the sealant assume an hourglass shape (which prolongs sealant life), and serve as a bond breaker to prevent bottom-side adhesion. Backer rod does not stain sealants and is chemically inert. They are non-gassing, non-exuding, and virtually dust-free. Due to physical and chemical inert nature, backer rod is compatible with virtually all known cold sealants, including self-leveling sealants – butyl, polysulfide, acrylic polyurethane, silicone, and most other cold-applied sealants.
Joint Preparation and Installation:
Clean all joints. Remove any concrete form-release agents, curing compound residue, laitance, and any other foreign materials.
To ensure good bond, joints must be clean and dry when the new sealant is installed. Air compressors must be equipped with traps for oil and moisture removal.
Install backer rod at depth recommended by sealant manufacturer – use a blunt tool.
Commonly used in expansion/contraction joints such as:
