Dow GREAT STUFF PRO™ Wall & Floor Adhesive - Manual (Page 3)

TIP: Never leave a foam dispensing
gun without a can of adhesive
attached unless it has been
thoroughly cleaned with GREAT
STUFF PRO™ Gun Cleaner.
Cleanup
• Excess adhesive can be cleaned
from the substrate while still
uncured using a dry cloth, putty
knife or paint scraper. Uncured
adhesive can be removed with
GREAT STUFF PRO™ Gun
Cleaner. Cured adhesive must be
mechanically removed or allowed
to wear off in time.
• For short-term storage, tighten
the flow control knob until fully
closed. Use can within 30 days
of initial use. Store upright with
foam dispensing gun attached. To
reuse, shake vigorously for one
minute before dispensing. Adjust
flow control knob to the open
position.
• For long-term storage, unscrew
can and use GREAT STUFF
PRO™ Gun Cleaner to clean
uncured adhesive from the
exterior assembly. Wear gloves
and safety goggles while
cleaning the gun. To clean the
foam dispensing gun’s interior
assembly, invert can of cleaner
and screw onto adapter, being
careful not to overtighten. Spray
until all adhesive is blown out of
the foam dispensing gun and only
cleaner is visible (approximately
half the can of cleaner will be
used). Allow the gun containing
the solvent to sit for several
minutes and repeat with a second
flush.
• Do not leave a can of cleaner
mounted on the foam dispensing
gun. This will dissolve the lip
seals inside the gun and render
it useless. Foam escaping at the
handle or trigger indicates a faulty
seal.
NOTE: If this happens, the gun should
be replaced. If the foam dispensing
gun has not been cleaned, add a new
can of GREAT STUFF PRO™ Wall &
Floor Adhesive immediately. If left
without a can attached, exposure to
air and moisture will cause the foam
in the gun to cure. A fresh can of
adhesive may be left attached to a
foam dispensing gun that has been
cleaned for up to 30 days.
TIP: Treat your gun like a tool. The
better you take care of it, the longer
it will last.
Safety and
Conditions
of Use
• Read the label and Material Safety
Data Sheet carefully before use.
• GREAT STUFF PRO™ Gun
Cleaner contains 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.
• 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™ Gun
Cleaner is 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 lace can in hot
water. Do not puncture, incinerate
or store at temperatures above
120ºF (149ºC).
• GREAT STUFF PRO™ Gun
Cleaner 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 temperatures above 240ºF
(116ºC) for long periods of time.
