    • 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.

    • 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.
  • Q.Are the Great Stuff™ Insulating Foam Sealant and Great Stuff Pro™ Polyurethane Foam Sealant cans recyclable and are there restrictions on their disposal?


    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 DuPont Contact Center (DCC) at 1-833-338-7668.

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

    Q.Can I clean the Great Stuff™ Black gun?



    Unscrew used Great Stuff Pro™ from dispensing gun.

    Clean the gun basket and tip by generously spraying and removing uncured foam with Great Stuff™ Foam Cleaner.

    Invert the can and install the cleaner onto the dispensing gun.

    Press the trigger to flush the foam into waste receptable until only the cleaner is visible.

    Allow gun to sit for several minutes and repeat with a second flush.

    Remove the can from the dispensing gun and spray into waste receptacle without the can until the gun is completely empty.

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


    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.How many windows can one can of GREAT STUFF™ Window & Door fill?


    Fills an average of four to six residential windows (36" x 60", a 3/8" gap, 1" deep) with a single 12-oz. can
