  • Q.Can Great Stuff™ products be used outdoors?


    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?


    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 do I get Great Stuff™ foam off the side of my house?


    There is no solvent that will remove cured insulating foam. If the foam has not cured yet, use Great Stuff Pro™ Foam Cleaner or fingernail polish remover (with acetone) to quickly remove the uncured foam. Test a small area of the substrate first as the chemicals in the nail polish remover and gun cleaner may not be compatible with the substrate being cleaned. For cured foam, remove as much as possible with a dull scraper or a hacksaw blade and then try scrubbing the remaining film with a non-abrasive cleaner. If that does not work, gradually move up to more aggressive means including sanding, sandblasting and repainting.
