Safety and Conditions of Use
• Read the label and Material Safety Data Sheet
carefully before use.
• GREAT STUFF PRO ™ Window & Door Insulating
Foam Sealant contains isocyanate and a
fl ammable blowing agent. Vapor may travel to
other rooms. Ensure adequate ventilation. Shut
off all pilot lights and extinguish open fl ames;
eliminate all sources of ignition before use. Do
not smoke or use lighters or matches while

• Do not breathe vapor or mist. Use in well-
ventilated areas or wear proper respiratory

skin and respiratory system, and may cause
sensitization by inhalation or skin contact.
• GREAT STUFF PRO ™ 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 contents are under pressure. 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 120ºF
(49ºC).
• GREAT STUFF PRO ™ products should not
be used around heaters, furnaces, fi replaces,
recessed lighting fi xtures or other applications
where the foam may come in contact with heat-
conducting surfaces. GREAT STUFF PRO ™ foam
is combustible and will burn if exposed to open
fl ame or sparks from high-energy sources. Do not
