Ratings may include incentivized customer reviews.
What Customers Are Saying
Customers overwhelmingly praise this spray foam for its exceptional ability to seal gaps, cracks, and drafts around pipes, windows, and crawl spaces. The powerful expansion and ease of application are frequently highlighted as standout features for reaching hard-to-access areas. Most note the product is messy and sticky, requiring gloves and cleanup with acetone or specialized wipes. Many report the nozzle clogs after first use, making it single-use only, though some find workarounds. Despite these drawbacks, the vast majority consider the sealing performance outstanding and well worth the trade-offs.

Fills gaps well, just super messy unless you're very careful

No
Would RecommendIf you don’t use it all on the first try, it will be unusable when you go get it… Also, the nozzle will start spinning by itself when you set the can down. And it’s not a wide spray if you spray it on the wall, it runs down the wall like a wooly bear…
Handy and effective for sealing
Would RecommendThis spray foam did exactly what I hoped. The straw applicator made it easy to reach into tight gaps around pipes, window frames, and baseboards without making a mess. It expands to fill the space and cures quickly
