    • Any uncured product that gets on the skin can be removed with acetone.
    • Best results if used when product temperature ranges from 60-90°F (15-32°C). The can should not be exposed to temperatures more than 120°F. Cured foam should not be exposed to temperatures in excess of 240°F.

    • Thread the SMART DISPENSER™ onto the valve until it is secure, ensuring there is no gap between the dispenser and the valve.
    • Do not unwind the dispenser after you have started using it.
    • Let up on the trigger slowly to release pressure in the straw and prevent spurts during the next use and to achieve the most consistent bead.

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

    A.

    Yes.
    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?

    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.
