HBR Backer Rod is a closed-cell, polyethylene foam backer rod joint filler that is used as a backing material for elastomeric and other cold-applied sealants. It helps the sealant assume the optimum shape to prolong service life and acts as a barrier to the flow of sealant through the joint. It will not absorb water.
