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.
