    Q.

    What is the difference between Great Stuff™ and Great Stuff Pro™ products?

    A.

    There are two key differences between Great Stuff™ and Great Stuff Pro™ products:

    • Great Stuff™ uses a straw dispenser; Great Stuff Pro™ has both straw- and gun-applicator options to dispense foam.
    • Can sizes are larger with Great Stuff Pro™ series, so yield is greater.
     
     
     
    Q.

    How do I get Great Stuff™ foam off of my skin?

    A.

    If the foam has not cured or hardened, use fingernail polish remover (with acetone); a polyglycol-based skin cleanser or corn oil may be effective. Then wash with soap and plenty of water. If the foam has hardened, there is no solvent that will remove it. It will not harm your skin and will wear off over time. To remove cured foam from skin, use a pumice stone (available at most drug stores) and warm, soapy water. Then apply petroleum jelly.

     
     
     
    Q.

    Can I clean the Great Stuff™ Black gun?

    A.

    Yes!

    1. Unscrew used Great Stuff Pro™ from dispensing gun.
    2. Clean the gun basket and tip by generously spraying and removing uncured foam with Great Stuff™ Foam Cleaner.
    3. Invert the can and install the cleaner onto the dispensing gun.
    4. Press the trigger to flush the foam into waste receptable until only the cleaner is visible.
    5. Allow gun to sit for several minutes and repeat with a second flush.
    6. Remove the can from the dispensing gun and spray into waste receptacle without the can until the gun is completely empty.
     
     
     
    Q.

    Are the Great Stuff™ and Great Stuff Pro™ cans recyclable and are there restrictions on their disposal?

    A.

    Since local regulations vary, it is best to contact your local waste disposal facility to inquire about disposal of pressurized aerosol cans. DuPont manufacturing facilities are typically not licensed to receive hazardous waste and therefore cannot take back used canisters. If you have additional questions, call our Customer Information Group at 1-866-583-BLUE (2583).

    Please see the attached document for more information surrounding the disposal and recycling information of Great Stuff ™ and Great Stuff Pro™ Foam products.

    Great Stuff™ can recyling 2015.pdf (93.25 KB)

    • Shake vigorously for a minimum of 60 seconds. If the can sputters, simply shake the can while held upside down.
    • Any uncured product that gets on the skin can be removed with acetone.  
    • Best results if used when product temperature ranges from 60-90°F (15-32°C). The can should not be exposed to temperatures more than 120°F. Cured foam should not be exposed to temperatures in excess of 240°F.
    • Firmly screw straw assembly onto valve and dispense SLOWLY.
    • Mist with water to speed cure.
    • Trim cured foam with serrated blade.
    • If applied outdoors, be sure to paint or cover foam to prevent discoloration and UV damage.

    If using GREAT STUFF PRO™ with the Foam Dispensing Gun, follow these additional steps before application:

    • With the can secured, set your desired bead size by adjusting the flow control knob on the back of the gun (bead can be adjusted from 1/8"-3"). Then, pull the trigger to fill the gun with foam, dispensing excess foam into an appropriate waste receptacle. Lastly, test the bead size before applying.
    • Tighten the flow control screw until fully closed for storage. Use can within 30 days of initial use.
    • Store upright with a foam dispensing gun attached.
    • Fill gaps <50%
    • Always leave a can of foam attached to the gun with the flow control screw closed.
    • When ready to change cans, shake the new can of foam for a minimum of 60 seconds.
    • NEVER leave a gun without a can of adhesive without a can of Great Stuff Pro™ attached unless the gun has been thoroughly cleaned with Great Stuff™ Foam Cleaner.
