Now I’m going to install and flash a brick mold door unit using DuPont™ FlexWrap™
and StraightFlash™ VF. I’m going to start with the head flashing first to avoid any
reverse laps. First adhere it to the back side of the brick mold. Pull the release paper
off, fold it against the head jamb, cut on a 45 degree angle, fold the head flap piece
down, and I’ll put a piece of release paper on the back side to protect the adhesive so
it doesn’t get stuck where you don’t want it to. I’ll use a J-roller to apply even
pressure, get good solid contact consistent across the door head and the back of the brick
mold. Putting the head flashing on is the first step, the next step is to put the jamb
flashing on. We have a piece of the StraightFlash™ VF, we’re going to flip this over and pull
off the release paper. This should extend two and a half inches up past the door head.
The piece should be cut at least six inches longer. And again we’ll apply the first
adhesive side to the back side of the brick mold. After it’s got contact we pull off
the second piece of release paper and we fold it against the door jamb. Cut this flap down
and protect both sides underneath with some release paper. At the top we make a 45 degree
angle cut, fold this piece over. We’re going to do the same with the other door jamb, 45
degree cut from the corner, fold our pieces down. The next step is to apply corner patches
using FlexWrap™ to cover this small open corner. Now I’ve got a sealed corner patch
over that slight open corner. After the sill flashing is installed, we install the door
unit. We’ll put the door in; I’ll fasten it plumb and level, and hang the door. We
want the door fully installed, plumb and level, the fit of the door checked, the complete
installation done 100 percent and then we’ll come back out and take care of the exterior
flashing details. After the door is completely installed, the door is fit, we’re comfortable
with the way the door is hanging, closing, we’re going to come back and take care of
the exterior flashing details. First we’ll remove the protective release paper we put
on the jamb flashing when we installed the versa flash on the back side of the brick
mold, we’ll remove the one on the other side and we’ll peel off the two pieces of
release paper. We’ve pulled the release paper off and we want to make sure we get
at least an inch of contact between these two pieces of the adhesive area on the jamb
flashing and the head flashing. We want to make sure that we get at least one inch of
contact between the adhesive of the jamb and the head piece on the back side. Get good
adhesive contact using the J-roller. After the head flashing and the jamb flashing is
adhered to the HomeWrap™ and the OSB for the head, we’re going to put a piece of
cap flashing over the brick mold of the door. Before we install the cap flashing we’re
going to apply a bead of DuPont™ sealant on the back edge. I’ll hold this so it just
extends past the edge a little bit and we’ll put a few screws in there to hold it. After
I’ve installed the metal cap flashing I’m going to finish off the flashing installation
by putting a piece of Flashing Tape over the top of the vertical leg of the cap flashing
and adhere it directly to the OSB sheathing which will direct any moisture that were to
get behind the HomeWrap™ down over top of the cap flashing. I’ll peel off a little
bit of the release paper to get started and I’ll install this piece so it extends beyond
the jambs an inch. Then I work my way across, again letting this last piece of Flashing
Tape extend at least an inch beyond the head flashing piece that we put on the back of
the brick mold. We’ll use the J-roller to roll it out. Take our head flap that we cut
when we cut the opening, fold it down, cut off that excess covered by the brick mold,
tape our 45 cut, and then we’ll tape that head flap all the way across the lower horizontal.
We’ll cover the exposed butyl with DuPont™ Tyvek Tape to prevent dirt from getting stuck
to it or any other stray materials. When then flooring is installed, we can lift up the
piece of FlexWrap™ that still has the release paper on the back, slide our flooring tight
up against the back of the threshold and cut off any excess FlexWrap™ with a utility
knife for a nice tight joint. And now we have a properly flashed brick mold door, using
DuPont™ FlexWrap™ and StraightFlash™ VF.
