So, I now intend to chisel away the grout and then squeeze in a backing rod and then apply silicone on top. Provides backing against which the sealant is applied, forcing the sealant to the sides of the joint for adhesion. Backer Rod is an integral component of sealant joints, it provides three main functions that allow the sealant joint to perform.
