5/8 Backer Rod : 5/8″ Backer Rod

Joint or opening must be clean, dry and free of obstructions. Using the Proper Sizing Chart on reverse side, select the proper rod diameter and cut to length or use directly from spool. With a blunt instrument or roller, uniformly install rod at the level recommended by the sealant manufacturer, specifier or architect involved. Generally, the depth of the joint after the backer rod is installed is one half the width. Very large and very small joints vary in terms of this depth ratio. Do not puncture, stretch or over compress.

Extruded round, closed cell, low density polyethylene (PE) foam material with a skin-like outer texture. Standard backer rod is non-absorbent, flexible and compressible allowing for easy installation in joints as a backup material for sealants. It’s available in spools in ¼” to 1 ¼” diameters or 6’ lengths for sizes over 1 ½” diameter. Standard backer rod is recommended for glazing installations, window and door applications, expansion joints, log construction, pavement joints or repairs and precast concrete joints and copings. It’s compatible with most cold-applied sealants.
