ABSTRACT:
Joints between surfaces are sealed by a method which cleans the joint surfaces, installs a backer rod between the joint surfaces, applies a sealant in the space over the backer rod and allows the sealant to cure. The backer rod is an open cell foam having an impervious skin. Preferably, when the surfaces are horizontal, as in a highway, the sealant used is a self-leveling sealant, preferably a silicone sealant.
