Dow ENERFOAM Operating instructions

The instructions outlined here
describe how to use ENERFOAM™
Professional Foam Sealant to fill
gaps and cracks around the home.
Designed to fill gaps up to 3" (75
mm), ENERFOAM™ Professional
Foam Sealant expands to take the
shape of cracks and voids, forming
a permanent, airtight and water-
resistant bond to vinyl, wood and
metal surfaces.* Once cured, it
remains soft and flexible, permitting
natural expansion and contraction
of surrounding surfaces.
To determine the amount of
ENERFOAM™ Professional Foam
Sealant required for an application,
see Table 1.
PREPARATION
1. Read and follow the Safety and
Conditions of Use instructions
below. Wear gloves, safety
glasses or goggles and
long sleeves. Provide good
ventilation and eliminate all
sources of ignition.
2. Shake can vigorously for 1
minute before dispensing and
between uses.
3. Gun-applied version: Invert can
and screw foam dispensing gun
assembly firmly onto valve as
shown in Figure 1. Screw until
finger-tight; do not overtighten
(Figure 2). When changing cans
using the foam dispensing gun,
tighten the flow control knob
before removing the empty can
(Figure 3). Use gun cleaner,
acetone or other adhesive
remover to remove any residual
foam from the attachment area
before attaching fresh can.
Straw-applied version:
Attach the nozzle by twisting it
clockwise into the valve.

*For cavities, cracks and penetrations larger than 3" (75 mm), Dow recommends FROTH-PAK™ Foam Sealant or FROTH-PAK™ FS Foam Insulation. For window and door framework, minimal-expanding GREAT STUFF PRO™
Window & Door Insulating Foam Sealant is proven not to distort or bow the framework, when properly applied.

APPLICATION
GUN-APPLIED VERSION:
1. Adjust flow control screw on
back of gun to an open position.
Immediately press trigger to fill
gun with foam while dispensing
into an appropriate waste
receptacle.
2. Keeping can inverted, insert
applicator nozzle into the
penetration to be filled and
begin dispensing foam slowly.
Fill gap less than 1/3 full to
allow for proper expansion.
3. The foam dispensing gun is
recommended to control size
of the foam bead (from 1/8"
to 3" [3 mm to 75 mm]). This
is achieved by squeezing the
trigger on the foam dispensing
gun or by adjusting the flow
control knob on the back of the
gun to set how far the trigger
can be pulled (Figure 5).
CAUTION:
Do not inject the foam sealant
into blind six-sided cavities, such
as window mullions. The foam
must be exposed to atmospheric
moisture to thoroughly cure.
TIP: Using grease or petroleum
jelly in the adapter of the gun
may reduce possibility of foam
gluing the can on the gun.
TIP: Apply foam in a continuous
bead, with no voids or breaks, to
achieve an effective seal.

4. If the gap is overfilled, stuff
excess cured foam into the gap
with a blunt tool or trim away
with a sharp knife. Foam will be
tack-free in less than 20 minutes
and can be trimmed in 1/2 hour.
It is fully cured 1 hour after
application.**
5. Clean foam dispensing gun
periodically by rubbing the end
on soft wood to free it from
foam. Do not use a sharp object
to clean foam dispensing gun.
Use a solvent cleaner such as
gun cleaner, acetone or other
adhesive remover between
extended periods of non-use.
6. To store partially used can,
tighten flow control screw
closed and store can upright
with gun attached. Use can
within 30 days of initial use.
7. To reuse, shake can vigorously
for 1 minute before dispensing
and follow dispensing
instructions stated above.
STRAW-APPLIED VERSION:
1. Attach the nozzle by twisting it
clockwise into the valve. Press
the button until the appropriate
size of foam bead is achieved.
Fill gap less than 1/3 full to
allow for proper expansion.
2. If the gap is overfilled, stuff
excess cured foam into the gap
with a blunt tool or trim away
with a sharp knife. Foam will be
tack-free in less than 20 minutes
and can be trimmed in 1/2 hour.
It is fully cured 1 hour after
application.**
3. Clean straw periodically by
rubbing the end on soft wood to
free it from foam.
4. When finished, bend the straw
back onto the plug on top of
the trigger assembly. The plug
prevents moisture from entering
and curing inside the straw or
valve.
5. To use after storage, gently
rotate or twist the straw to break
the adhesive bond of the foam.
Pull the straw off of the plug and
dispense.
CLEANUP
• Onsolidsurfaces,uncured
foam can be dissolved with
gun cleaner, acetone or other
adhesive remover. Cured foam
must be mechanically removed
or allowed to wear off in time.
• Tocleanfoamdispensinggun,
install a can of gun cleaner,
acetone or other adhesive
remover to the foam dispensing
gun and spray until all foam
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 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. If
this happens, the gun should be
replaced. If the foam dispensing
gun has not been cleaned, add
a new can of ENERFOAM™
Professional Foam Sealant
immediately. If left without a can
attached, exposure to air and
moisture will cause the foam in
the gun to cure.
DISPOSAL
• Disposaloffullorpartially
used aerosol cans must be in
compliance with all federal,
state/provincial and local laws
and regulations. Regulations
vary in different locations.
Empty cans are not considered
hazardous waste and may be
disposed of an nonhazardous
household waste.
SAFETY AND
CONDITIONS OF USE
• ReadthelabelandMaterial
Safety Data Sheet carefully
before use.
• ENERFOAM™Professional
Foam Sealant 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.
• ENERFOAM™Professional
Foam Sealant 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
120°F (49°C).
• ENERFOAM™Professional
Foam Sealant may be used
on vinyl, wood, composite
and metal (aluminum or steel)
substrates. The product adheres
best when surfaces are clean
and free of oil or chemicals.
• Extremelycoldtemperatures
can affect dispensing perfor-
mance.
• Skinofcuredfoamcan
discolor if exposed to direct
or continuous sunlight for 24
hours or more. Foam should be
painted or coated if prolonged
exposure to sunlight is
expected.
• Usingfoamdispensingguns
(shown in Figure 1) simplifies
the application of ENERFOAM™
Professional Foam Sealant. 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.

TIP: Always close the flow
control knob when the gun is
not in use.
TIP: Treat your gun like a tool.
The better you take care of it,
the longer it will last.
