For Use with Cold Applied Sealants
Closed Cell Polyethylene Foam
Nonimpregnated, nonstaining, and nonbleeding
Inert and does not adhere to sealants

Meets all requirements of the 1990 Clean Air Act

Is a "Domestic End Product" as defined by the Buy American Act, Title 41 USC 10

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 rods do not stain sealants,  and are 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

Diameter of Rod: 3/8"
Feet per Roll: 50 Ft. 

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:
Curtain Wall Partitions
Bridge and Highway Construction
Parking Decks
Pre-Cast Assemblies
Glazing Applications
Panel Systems
