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
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.
Where can I use Great Stuff™ and Great Stuff Pro™ products?
Great Stuff™ and Great Stuff Pro™ products can be used in a variety of interior and exterior applications, most commonly in air sealing and home retrofit applications.
