3. PRODUCT DESCRIPTION
GREAT STUFF PRO
™
Gaps & Cracks
Insulating Foam Sealant is a minimal-
expanding, single component
polyurethane foam sealant for general
purpose building envelope air sealing.
In the United States, the sealant is easily
identified by its bright orange color. It
has led the way in the industry by being
recognized as a fireblock, which means
it resists the free passage of flames to
other areas of the building through
concealed spaces.

dispensing guns simplifies the application
of GREAT STUFF PRO

Gaps & Cracks. 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, allowing a can to be
reused up to one month later.

Gun Cleaner is a
solution to simplify cleanup of uncured
polyurethane foam from dispensing guns
and work areas. Cured foam must be
mechanically removed or allowed to wear
o in time.
