What is Great Stuff™?

Can I use Great Stuff™ and Great Stuff Pro™ foam to air seal my electrical receptacles?
Great Stuff™ and Great Stuff Pro™ foam can be used to air seal around and behind electrical boxes and insulated wires but should never be used inside a box where it may be exposed to bare copper wires
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.
*Note: Great Stuff™ Insulating Foam Sealants are not for use in aviation, or food/beverage contact, or as structural support in marine applications.
