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 the first
foam sealant to be recognized as
a fireblock, which means it resists
the free passage of flames to
other areas of the building through
concealed spaces.
BASIC USE
GREAT STUFF PRO
™
Gaps &
Cracks Insulating Foam Sealant fills
and seals gaps up to 3" (75 mm).*
GREAT STUFF PRO
™
Gaps &
Cracks Insulating Foam Sealant:
• expands to take the shape of
cracks and voids, forming an
airtight and water-resistant bond
to wood, metal, masonry, glass
and most plastics
• reduces pathways where insects
can enter
• installs in minutes (tack-free
in 5-10 minutes, trims within
30 minutes)
GREAT STUFF PRO
™
Gaps &
Cracks Insulating Foam Sealant is
both cost-effective and effective as
an air sealant.
SIZES
GREAT STUFF PRO
™
Gaps &
Cracks Insulating Foam Sealant is
available in 24 oz (680 g) and 30 oz
(850 g) gun- and reusable straw-
applied versions. See Table 1 for
yields. Contact your Dow sales
representative with questions.
ACCESSORIES
Using one of several PRO Series
foam 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.
GREAT STUFF PRO
™
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 off in
time.
