PRO Series Foam Dispensing Gun
Care Tips
• Do not breathe vapor or mist.
Use in 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.
• GREAT STUFF PRO
™
sealant
and adhesive products are very
sticky and will adhere to most
surfaces and skin. Do not get
foam on skin. Wear 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
120°F (49°C).
• GREAT STUFF PRO
™
products
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.
GREAT STUFF PRO
™
foam will
burn if exposed to open flame or
sparks from high-energy sources,
and it will start to thermally
degrade if exposed to tempera-
tures above 240°F (116°C).
Loading a Can of
GREAT STUFF PRO
™
Product
To load a can of GREAT STUFF
PRO
™
Insulating Foam Sealant or
Adhesive to a PRO Series foam
dispensing gun, make sure that
the threads on the can align with
the threads on the gun. Cross-
threading the can to the gun can
cause the foam to dispense under
the valve. Screw the can onto the
gun firmly, but do not overtighten.
Control Bead Size With
Flow Control Knob
Use the flow control knob on
the back of the gun to vary bead
size. Unscrewing the knob enables
additional “play” in the trigger.
Bead size can be controlled from
1/8" to 3" (3 mm to 76 mm).
Introduction
A PRO Series foam dispensing
gun, once activated, is just like a
garden hose that has been turned
on – it’s pressurized right to the
tip. When a can of GREAT STUFF
PRO
™
Insulating Foam Sealant or
Adhesive is loaded onto the gun,
the foam goes right to the tip.
One pull of the trigger, and foam
is dispensed.
But remember, since the foam
is cured by moisture in the air,
allowing air into the gun assembly
can cause the foam to cure and
render the tool useless. Follow
the steps in this document to help
ensure long-lasting performance
from any PRO Series foam dis-
pensing gun.
