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.
