L. Insert backer rod and apply sealant. Install siding, and insert backer rod between the each
jamb cover and the exterior finish material as deep as it will go. Apply a bead of high quality
exterior sealant on top of the backer rod and a corner bead to the top of the head frame
expander. Shape, tool, clean excess sealant. When finished, the sealant should be the shape of
an hourglass.
Note: Backer rod adds shape and depth for the sealant line. This method creates a more
flexible sealant line capable of expanding and contracting.
