Preparation
1. Apply GREAT STUFF PRO ™
Window & Door when tem-
peratures are between 40°F
and 100°F (4°C and 38°C),
at relative humidity ≥20%.
2. Be sure window/door and
frame surfaces are clean and
oil- and chemical-free.
3. Shake can vigorously for 60
seconds before dispensing
and between uses. Shaker
ball must tap. To free shaker
ball, rap can firmly against
base of hand.
4. Invert can and screw foam
dispensing gun (or threaded
end of straw assembly firmly)
onto valve as shown in
Figure 2. Screw until finger-
tight; do not overtighten
(Figure 3).
(When changing cans using
the foam dispensing gun,
tighten the flow control
knob before removing the
empty can [Figure 4]. Use
GREAT STUFF PRO
™ Gun
Cleaner to remove any
residual foam from the
attachment area before
attaching fresh can.)
5. Dispense foam for 3-6
seconds to purge air from
gun or straw.
Application
1. Keeping can inverted, insert
applicator nozzle into the
space between the window
or door and the rough
opening and begin applying
foam (Figure 5). Fill openings
less than 50 percent full to
allow room for expansion.
Do not overfill gap (Figure 6).
GREAT STUFF PRO
™
Window & Door should be
applied around all four
sides of a window opening,
and top and sides of a door
opening. Diameter of foam
bead should not exceed 3"
(75 mm).

TIP
Apply foam in a contin-
uous bead, with no voids
or breaks, to achieve an
effective seal.
CAUTION:
Do not inject the foam
sealant into blind six-
sided cavities, such as
window mullions. The
foam must be exposed to
atmospheric moisture to
thoroughly cure.
