General Instructions
DuPont
Flashing Systems products should be installed on clean, dry surfaces that are free of frost. Wipe surfaces to
remove moisture, dirt, grease and other debris that could interfere with adhesion.

Remove all wrinkles and bubbles by smoothing surface and repositioning as necessary.
When flashing the sill area for windows and doors, DuPont recommends the use of 7” wide DuPont
FlexWrap
for
2”x 4” framing and 9” wide DuPont
Flexwrap
for 2” x 6” framing. When rigid back dams are required or desired, an
option would be to use a ¾” corner guard (back dam) cut to the length of the sill and nail into place on the interior edge of
the sill prior to installation of DuPont
FlexWrap
. Then install DuPont
FlexWrap
over sill and corner guard back dam.
Door and window rough sill framing must be level or slightly sloped to the exterior to ensure proper drainage to the
exterior. DuPont recommends the use of the SureSill
Sloped Sill Pan
, manufactured by SureSill, Ltd, on all exterior doors
and in certain applications on windows. This best practice ensures continuous support with positive slope to the exterior.
Please contact your local DuPont
Tyvek
Specialist for additional information and installation instructions.
DO NOT STRETCH DuPont
FlexWrap
when installing along sills or jambs. DuPont
FlexWrap
is only intended to be
stretched when covering corners or curved sections.
DuPont
Flashing Systems products perform best when installed at temperatures above 25°F (–4°C).
Avoid placing DuPont
Tyvek
®
Wrap Caps where flashing will be installed; however, DuPont
Tyvek
®
Wrap Caps can be
applied over the flashing.
Where buildings could be exposed to extreme weather conditions (ie. sustained wind-driven rain above 50mph), install a
high pressure skirt to help prevent water intrusion at the sill.
Priming is generally not required for adhering DuPont
Flashing Systems products to most common building materials.
However, adverse weather conditions or cold temperatures may require use of a primer to promote adhesion. Additionally,
