Backing rod is a closed cell, non absorbent and chemically inert polyethylene foam flexible rod. Polyrod is designed for use as a compressible joint backing material for elastomeric and a wide variety of cold applied joint sealants.
Expansion, isolation, control and coping joints.
Highway and pavement joints.
Perimeter of window and door frames.
Log home chinking.
Select a backer rod whose diameter is at least 20% larger but not greater than 33% of the joint width. This will ensure that the backer rod remains in compression and in place during sealant installation. The backing rod shall be inserted into the joint by using a blunt tool or roller and forced gently into the joint till the desired depth is achieved, whilst making no damages to the joints & edges.
