Product FAQ

Q.
What is Great Stuff™?
-
A.
Great Stuff™ is the brand name for a line of one-component insulating foam sealants that can help make your home more comfortable and energy efficient by sealing the gaps and cracks where air conditioned and heated air escape. Great Stuff Pro™ Polyurethane Foam Sealants can be used for both small and large air sealing and retrofit applications by DIY’s or professionals. Great Stuff™ comes in cans with a straw applicator or the new patented Smart Dispenser™. Cans are in 12, 16, and 20 oz sizes. Great Stuff Pro™ series is available in larger cans (20,24, & 30 oz sizes) and use the dispensing guns to apply.
-
Q.
Can Great Stuff™ products be used outdoors?
-
A.
Yes.
Great Stuff™ and Great Stuff Pro™ products can be used outdoors. However, cured foam will discolor if exposed to ultraviolet (UV) light. If left exposed, the foam will eventually crumble. Paint or coat foam for best results in outdoor applications.
Great Stuff Pro™ Gasket is not approved for used outdoors
-
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.

Helpful Tips
- 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.
- Great Stuff ™ cans featuring the straw tube applicator will seal shut if left to sit for more than 2 hours after its last use.
If using GREAT STUFF™ SMART DISPENSER™, follow these additional steps before application:
- Great Stuff™ cans featuring the Smart Dispenser™ may be reused up to 30 days with the straw left attached to the canister, just clean the tip after your first use. For best results:
- Thread the SMART DISPENSER™ onto the valve until it is secure, ensuring there is no gap between the dispenser and the valve.
- Do not unwind the dispenser after you have started using it.
- Let up on the trigger slowly to release pressure in the straw and prevent spurts during the next use and to achieve the most consistent bead.
- Shake vigorously for a minimum of 60 seconds. If the can sputters, simply shake the can while held upside down.
