Some of the most common uses for expanding foam are for sealing cracks and holes around the home, such as along the foundation or in the attic. It also is a standard product for using around window and door installations.
In this regard, what will expanding foam not stick to?
Expanding polyurethane foam sealant requires moisture to expand and cure. If you're applying foam to dry wood or other dry surfaces, or working on a day with little humidity, misting the area first will help the foam expand and cure faster. Foam sealant won't stick well to a wet surface.

This version of Great Stuff expanding foam also offers water resistance. It is not meant to be in constant direct contact with water but is suitable for outside locations where exposure to water is likely. Examples include sealing around external piping and faucets, basement areas, and electrical and cable lines.
- Wipe excess spray foam insulation from the skin while the foam is still wet.
- Wipe the area with acetone.

- Rub the dried foam with a pumice stone to wear as much of the foam away as possible.
- Apply lanolin or petroleum jelly generously to the affected area.
