Insulating Foam Sealant
GREAT STUFF PRO
™
Window &
Door Insulating Foam Sealant air
seals the gap around an installed
window or door frame and the rough
opening. The product also reduces the
amount of moisture intrusion through
fenestration openings, which can help
prevent moisture damage and wood
rot. This flexible polyurethane foam
expands only enough to generate
an effective seal, and is proven to
not distort or bow window and door
frames when properly applied.
To determine the amount of GREAT
STUFF PRO

for an application, see Table 1.
Safety and Conditions
of Use
Data Sheet carefully before use.
™
Insulating
Foam Sealants contain isocyanate
and a flammable blowing agent.
Vapor may travel to other rooms.
Ensure adequate ventilation. Shut
off all pilot lights and extinguish
open flames; eliminate all sources
of ignition before use. Do not smoke
or use lighters or matches while
dispensing foam.
well-ventilated areas or wear proper
respiratory protection. Isocyanate
is irritating to the eyes, skin and
respiratory system, and may cause
sensitization by inhalation or skin
contact.
™
foam is very
sticky and will adhere to most
surfaces and skin. Do not get foam
on skin. Wear long sleeves, gloves,
and goggles or safety glasses.
Cured foam must be mechanically
removed or allowed to wear off in
time.
The can may burst if left in areas
susceptible to high temperatures,
such as motor vehicles, or near
radiators, stoves or other sources of
heat. Do not place can in hot water.
Do not puncture, incinerate or store
at temperatures above 120°F (49°C).
™
foam is
combustible and will burn if exposed
to open flame or sparks from high-
energy sources. Do not expose to
temperatures above 240°F (116°C).
GREAT STUFF PRO
™
foam should
not be used around heaters,
furnaces, fireplaces, recessed
lighting fixtures or other applications
where the foam may come in contact
with heat-conducting surfaces. For
proper ventilation of combustion
appliances, visit www.epa.gov/iaq/

foam into large or confined cavities
such as behind holes in drywall or
under tub wall surrounds where
flammable vapors may collect. Foam
must be exposed to atmospheric
moisture to thoroughly cure.
Preparation
1. GREAT STUFF PRO
™
Window &
Door may be used on vinyl, wood,
composite and metal (aluminum
or steel) surfaces. The product
adheres best when surfaces are
clean and free of oil or chemicals.
2. GREAT STUFF PRO
™
Window
& Door should be applied at
temperatures between 40°F and
100°F (4°C and 38°C) at relative
humidity ≥20%.
3. Skin of cured foam can discolor if
exposed to direct and continuous
sunlight for 24 hours or more. Foam
should be painted or coated if
prolonged exposure to sunlight is
expected.
4. Using one of the PRO Series
foam dispensing guns simplifies
the application of GREAT STUFF
PRO
™
Window & Door. In addition
to enabling pinpoint application
control, an airtight and moisture-
tight seal between the gun and the
can prevents the foam from curing
and blocking the dispensing valve.
5. Shake can vigorously for 1 minute
before dispensing and between
uses. Shaker ball must tap. To free
shaker ball, rap can firmly against
base of hand.
6. Invert can and screw foam
dispensing gun (or threaded end of
straw assembly firmly) onto valve
as shown in Figure 1. Screw until
finger-tight; do not overtighten or
cross-thread. (When changing cans
using the foam dispensing gun,
tighten the flow control knob before
removing the empty can [Figure 2].
Use GREAT STUFF PRO
™
Gun
Cleaner to remove any residual
foam from the attachment area
before attaching fresh can.)
7. Dispense foam for 3-6 seconds to
purge air from gun or straw.
