Hardware Express 157901 Great Stuff Expanding Spray Foam Sealant, 12 oz.

Hi Groovegirl121, Thank you for sharing your concerns with us regarding GREAT STUFF™ Insulating Foam Sealant products. We apologize for any inconvenience you may have encountered. For further information and assistance please contact our Customer Information Group at 1-800-441-4369. If the foam has not cured or hardened, use acetone or fingernail polish remover (with acetone) to remove the foam being careful not to spread it. GREAT STUFF™ Insulating Foam Sealant products will chemically bond to just about all surfaces in a matter of minutes. Once cured, it cannot be removed with solvents and the only option is mechanical removal. On hard, smooth, or polished surfaces this may be accomplished very carefully with a single-edged razor blade. If this does not work, or if the foam is on a soft or porous surface, the only option is to attempt to remove it using a non-abrasive cleanser. The more effort spent scrubbing, the more likely it is to see positive results. If the non-abrasive cleanser does not work, consider replacement or refinishing. A more aggressive approach such as steel wool or sandpaper will damage the underlying surface. Only UV light will break the foam down and this takes months. Heat has no effect on the foam. It may soften, but it will not melt and the resulting fumes may be harmful.
