5. Cut two pieces of
self-adhered ashing
9" wide by the sill
pan width + 3" long.
a. For continuous
slab landings
only, cut out the
insidecorner.
b. Adhere the pieces
of ashing to the
inside corners.
Stretch ashing
as needed to
cover corners and
layat.
6. Smooth gaps or
bubbles beneath
self-adhered ashing
with a J-roller
(remove and replace
if necessary).
7. Seal back corners of
sill pan with sealant.
8. For step-down
landings only, cut
plastic drain screen
to length of sill +
2" and staple 1/2"
below sill edge. The
drain screen provides
a path for air to
dry any incidental
moisture in the
rough opening.
End of Stud-Framed
Wall Instructions,
continue with section 6, “INSTALL DOOR.”
PREPARE BUILDING WRAP
Verify these steps are allowed by the building wrap manufacturer.
1. Trim the sides
sufciently to allow
the nailing n to be
mounted against the
sheathing.
2. If the door extends
beyond the exterior
plain of the building
and a drip cap is
desired, at the head,
slit building wrap
6" at 45°. Tape
up as shown. We
recommend installing a drip cap because this integrates the building
wrap and drip cap to protect the structure and the product from
incidental water.
INSTALL JOBSITE FABRICATED SILL PAN
Note! The rest of the steps in this section only apply to a job site
fabricated sill pan. If installing a sill pan that you have purchased,
follow manufacturer's instructions for installation and skip to section 6,
“INSTALL DOOR.”
3. Apply spray adhesive/primer to the sill pan and surrounding area.
Follow manufacturer’s instructions for application methods.
4. Cut a piece of self-
adhered ashing the
length of the sill and
apply over the sill
pan as shown. The
bottom of the sill pan
should be completely
covered by the self-
adhered ashing. For
step down landings,
fold ashing down
as shown. For
continuous slabs,
trim ush with rough
opening.

and the concrete/masonry with sealant.
2. Cover the buck and the surrounding concrete/masonry at the head
and jambs (apply over sill pan if installing a job site fabricated
sill pan) with liquid applied or self-adhered ashing. If using self-
adhered ashing, follow manufacurers’ instrucions for appropriate
use of primers and other application methods.
