Q.What is the difference between Great Stuff™ and Great Stuff Pro™ products?
A. There are two key differences between Great Stuff™ and Great Stuff Pro™ products: Great Stuff™ uses a straw dispenser; Great Stuff Pro™ has both straw- and gun-applicator options to dispense foam. Can sizes are larger with Great Stuff Pro™ series, so yield is greater.
Q.How do I get Great Stuff™ foam off of my skin?
A. 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.Can I clean the Great Stuff™ Black gun?
A. Yes! Unscrew used Great Stuff Pro™ from dispensing gun. Clean the gun basket and tip by generously spraying and removing uncured foam with Great Stuff™ Foam Cleaner. Invert the can and install the cleaner onto the dispensing gun. Press the trigger to flush the foam into waste receptable until only the cleaner is visible. Allow gun to sit for several minutes and repeat with a second flush. Remove the can from the dispensing gun and spray into waste receptacle without the can until the gun is completely empty.
Q.Can mice, insects or other pests chew through Great Stuff™ foam?
A. 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.
