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.
