Note: be careful don’t use over heat to anything. ### ⭐⭐⭐⭐⭐ Follow instructions, be quick, and dont bother trying to pour it down a funnel *by T***S on July 7, 2019* Its foamy, 4 gallon was not quite enough to re foam a 19ft sea ray monoco, it is very chemical resistant, wear gloves it's been weeks and I still have some of this stuff stuck to my finger nails ### ⭐⭐⭐⭐ Great Product, Didn't Expand as Advertised *by J***P on January 2, 2021* The foam did exactly the job I needed and performs perfectly for my project. My only complaint is the foam did not expand to the advertised volume. I purchased the 2 lb 4 gallon kit and after all the product was mixed I only yielded about 12 cubic feet, vs. the advertised 16 cubic feet. I would buy this again but do so aware that I needed more product. ## Frequently Bought Together - TRUE COMPOSITES Liquid Urethane Pour Foam Base-2 Part Closed Cell Rigid Pour Foam-2 lb Density-Fast-Acting Formula-Boat Buoyancy, Flotation, Filling, Soundproofing & Insulation-4 Gallon Kit - Wax Additive - 4 oz Surfacing Agent for use with Gelcoat and Polyester resins --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/103409779-liquid-urethane-pour-foam-base-2-part-closed-cell-rigid](https://www.desertcart.co.uk/products/103409779-liquid-urethane-pour-foam-base-2-part-closed-cell-rigid) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-18*
