FillPro® Standard Backer Rod (formerly ITP Standard) is an extruded round, closed-cell, low density polyethylene 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.
Commonly used in glazing installations, window and door applications, expansion joints, curtain wall joints, partitions, log construction, pavement joints, repairs, pre-cast units and copings.
FillPro Standard is an ideal non-absorbent backer rod used to control sealant depth and create a back stop to allow proper wetting of the joint surfaces and yield a proper bond breaker between the backer rod and the sealant. Limiting the depth of the sealant prevents excessive use, saving on caulk or sealant. Standard backer rod can also be used as a temporary joint seal.
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.
