Acts as a bond breaker, preventing what is commonly referred to as three sided adhesion.
The backer rod supports tooling. the sealant is pushed to the bond line with a spatula, ensuring wet-out of the sealant to the substrate.
Promotes an hour glass shape, this maximizes the bond area but keeps the depth of sealant consistent in the middle allowing for movement.
