What is the difference between Great Stuff™ and Great Stuff Pro™ products?
There are two key differences between Great Stuff™ and Great Stuff Pro™ products:
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.
Can I clean the Great Stuff™ Black gun?
Can mice, insects or other pests chew through Great Stuff™ foam?
Rodents and small animals, if determined enough, can chew through many materials, including Great Stuff™ foam. We have specifically designed a variation of our Great Stuff™ foam to solve this issue, Great Stuff™ Pestblock and Great Stuff Pro™ Pestblock. They BLOCK insects and pests from entering the home by sealing gaps, cracks and holes where they commonly enter. Great Stuff™ Pestblock and Great Stuff Pro™ Pestblock expand to fill, seal and insulate gaps up to 1" (25 mm), forming a long-lasting, airtight and water-resistant barrier.
