What Customers Are Saying

The product is generally effective at filling gaps and holes, especially in larger openings, and has fire-retardant properties that allow it to expand significantly. However, some users reported issues with controlling the nozzle, the foam continuing to expand after application, and the product not being approved for certain fire-rated applications. The product can also be messy and difficult to clean up. Overall, the product is useful for many home improvement tasks, but users should exercise caution with the amount used and ensure it is appropriate for their specific application.

Wish I had my foam gun instead of this

Would Recommend

Foam poured out very quickly - I've gotten spoiled by using a foam gun -the gun offers much more precise application and extended use

Not reusable so make sure you are ready to use it.

Would Recommend

Good product but it’s not reusable so it can waste a lot of the can if you don’t plan accordingly. It expands a good bit to fill any gaps.
