SYSTEM OVERVIEW
General Information
The instructions outlined here describe how to use DuPont™
Enerfoam™Professional Foam Sealant* to fill gaps and cracks
around the home.
Designed to form a durable, airtight and water-resistant seal
in gaps up to 3” (75 mm), Enerfoam™expands to take the shape
of cracks and voids, forming a permanent, airtight and water-
resistant bond to wood, brick, vinyl, foam board, metal and most
plastics.** Once cured, it remains soft and flexible, permitting
natural expansion and contraction of surrounding surfaces.
In the U.S., Enerfoam™ is also recognized as an effective fireblock
penetration sealant. Applications include adhering insulated
concrete forms, architectural foam and drywall, and sealing
cracks and voids such as pipe penetrations. The foam expands
only enough to generate an effective seal, retaining elasticity as
the structure expands and compresses. To determine the amount
of Enerfoam™required for an application, see Table 1.
* DuPont™Enerfoam™Professional Foam Sealant is a former product of The Dow Chemical Company.
** For cavities, cracks and penetrations larger than 3” (75 mm), DuPont recommends Froth-Pak™Foam Sealant or Froth-Pak™ Foam Insulation. For window and door framework, minimal-expanding
DuPont™Great Stuff Pro™Window & Door Polyurethane Foam Sealant is proven not to distort or bow the framework when properly applied.

Safety and Conditions of Use
•Read the label and Material Safety Data Sheet carefully
before use.
•Enerfoam™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™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™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
performance.
•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 one of the PRO Series foam dispensing guns
(shown in Figure 1) simplifies the application of Enerfoam™.
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.

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 2. Screw until finger-tight; do
not overtighten (Figure 3). When changing cans using the foam
dispensing gun, tighten the flow control knob before removing
the empty can (Figure 4). Use DuPont™Great Stuff Pro™Foam
Cleaner to remove any residual foam from the attachment
area before attaching fresh can.

INSTALLATION
Straw-applied version:
Attach the nozzle by twisting it clockwise into the valve.
Outdoor water faucet Fireplace gas line
Pipe penetration Sewer plumbing penetration
Electrical wire penetration Wall-ceiling juncture
Electrical outlet* Attic hatch
HVAC vent
*Foam should be applied around the edges of the metal box. Do not apply within
the metal box.

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.* Tip: Using grease
or petroleum jelly in the adapter of the gun may reduce
possibility of foam gluing the can on the gun.
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
DuPont™Great Stuff Pro™Foam Cleaner between extended
periods of non-use. Tip: Treat your gun like a tool. The better
you take care of it, the longer it will last.
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. Tip: Always close the flow control knob
when the gun is not in use.
7. To reuse, shake can vigorously for 1 minute before dispensing
and follow dispensing instructions stated above.
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. 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.
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.
Tip: Apply foam in a continuous bead, with no voids or
breaks, to achieve an effective seal.
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).
*Dependent upon temperature, relative humidity and size of foam bead
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.
Clean Up & Disposal
•On solid surfaces, uncured foam can be dissolved with
Great Stuff Pro™Foam Cleaner. Cured foam must be
mechanically removed or allowed to wear off in time.
•To clean foam dispensing gun, install a can of Great Stuff Pro™
Foam Cleaner 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 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 as nonhazardous household waste.
