Where Should You Not Use Great Stuff?

When should you not use Great Stuff foam?

Great Stuff is a brand of expanding foam insulation commonly used to fill gaps and cracks around the home. However, it’s not suitable for every application. Here are a few instances where you should not use Great Stuff foam:

Around Heat Sources: Great Stuff foam is flammable and should not be used near open flames or heat sources, such as furnaces, water heaters, fireplaces, or recessed lighting fixtures.

Large, Enclosed Cavities: Expanding foam can exert considerable pressure as it cures. It can warp or break the surrounding material if used in large, enclosed spaces.

Moisture-Sensitive Areas: While some versions of Great Stuff foam are waterproof, they aren’t intended for areas with continuous water exposure or high humidity, such as inside a shower or bath enclosure.

Moving Parts: The foam hardens as it dries, so it shouldn’t be used around doors, windows, or other elements that need to move or be adjusted.

Visible Areas: Once cured, Great Stuff foam is difficult to remove and can’t be easily painted over or made to blend in with surrounding materials. Therefore, it’s not the best choice for visible areas unless it will be covered with something else.
