Epe Foam Rods

Backer Rod's four main benefits: 1.Increase elasticity in the joint sealant. 2.Reduce caulk consumption by controlling sealant depth— this prevents excessive use of caulking or sealant. 3.Force adhesive into contact with the sides of the joint creating an hour-glass shape for a superior bond. 4.Create a "bond-breaker" which allows the joint to be easily cleaned out and refilled as needed over time.
