Note: Application of closed cell foam backer rod
and sealant does not apply to stucco.
A. Insert closed cell foam backer rod into the space
around the door as deep as it will go. This should
provide at least a 1/2” clearance between the
backer rod and the exterior face of the door.
Note: Backer rod adds shape and depth for
the sealant line.
B. Apply a bead of high quality exterior grade
sealant to the entire perimeter of the door. On
doors where the bottom fin has been removed,
insert sealant into the spaces between the bottom
of the door and the sill support and connect it to the
perimeter sealant.
Note: Refer to the sealant manufacturer’s label
to Confirm compatibility with vinyl and the
adjoining building components and priming
requirements.
C. Shape, tool and clean excess sealant. When
finished, the sealant should be the shape of an
hourglass.
Note: This method creates a more flexible sealant
line capable of expanding and contracting.
When applying siding, brick veneer or other exterior finish material, leave adequate
space between the door frame and the material for sealant. Refer to the illustration
corresponding to your finish material.
Note: The sealant details shown are standard recommendations from the sealant
industry. Contact your sealant supplier for recommendations and instructions for these
and any other applications.
