Review: USE SPARINGLY!!! - So I used this to make a seat insert for my race car. I did not know how much to use... so I used the entire thing. I poured it into a trash bag and sat in the seat. The foam expanded so much that it pushed me out of the race car... foam got on me.. the car.. the seat... the steering wheel. USE SPARINGLY!!!!! Foam works very well. Hardens nicely and you can add layers. If I had read the instructions, this would have been much easier. I had to order more foam since I wasted the entire first batch. I recommend actually reading the instructions. Review: Good quality, doesn’t expand very much - Excellent item. I’ve used it to ship expensive items on usps. Foam is sturdy. But it doesn’t expand a lot . So you must use a lot of the chemicals to fill in a void . ## Features - Fast-Acting Liquid Urethane Foam: Fast-acting formula provides quick buoyancy, flotation, filling, soundproofing and insulation. - High Density Foam: 2 lb density foam provides excellent insulation and buoyancy for boats and other watercraft. - Waterproof and Durable: The urethane foam is waterproof and durable for long-lasting use in wet environments. - Easy to Apply: The liquid foam can be easily applied to any surface for quick and easy buoyancy and insulation. - Complete Kit: The 1/2 gallon kit includes enough foam to cover a small to medium-sized boat or other watercraft. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B079H225XM | | Best Sellers Rank | #296,420 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #56 in Packaging Foam | | Brand | TRUE COMPOSITES | | Brand Name | TRUE COMPOSITES | | Country of Publication | USA | | Customer Reviews | 4.1 out of 5 stars 89 Reviews | | Item Weight | 907 g | | Manufacturer | Polymer Planet | | Manufacturer Part Number | 2LBFOAMHGK | | Material | Urethane Foam | | Material Type | Urethane Foam | | Model Number | 2LBFOAMHGK | | Number of Items | 2 | | Number of Packs | 2 | | UPC | 850019564013 | | Unit Count | 64.0 Fluid Ounces | ## Product Details - **Brand:** TRUE COMPOSITES - **Manufacturer:** TRUE COMPOSITES - **Material:** Urethane Foam - **Number of Packs:** 2 - **UPC:** 850019564013 ## Images ![Liquid Urethane Closed Cell Rigid Pour Foam 2 Lb Density - 1/2 Gallon Kit Total - Image 1](https://m.media-amazon.com/images/I/81VxDEKvvUL.jpg) ![Liquid Urethane Closed Cell Rigid Pour Foam 2 Lb Density - 1/2 Gallon Kit Total - Image 2](https://m.media-amazon.com/images/I/81diGpbkLhL.jpg) ![Liquid Urethane Closed Cell Rigid Pour Foam 2 Lb Density - 1/2 Gallon Kit Total - Image 3](https://m.media-amazon.com/images/I/61AWd-ccezL.jpg) ![Liquid Urethane Closed Cell Rigid Pour Foam 2 Lb Density - 1/2 Gallon Kit Total - Image 4](https://m.media-amazon.com/images/I/61cRIlviR+L.jpg) ![Liquid Urethane Closed Cell Rigid Pour Foam 2 Lb Density - 1/2 Gallon Kit Total - Image 5](https://m.media-amazon.com/images/I/514Vx--tkvS.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ USE SPARINGLY!!! *by A***. on 6 May 2021* So I used this to make a seat insert for my race car.

But it doesn’t expand a lot . So you must use a lot of the chemicals to fill in a void . ### ⭐⭐⭐⭐ Works as advertised. *by N***H on 25 May 2020* It mixes easily and creates a very sturdy, bouyant foam. Just a heads up that it begins to expand QUICKLY and you need to be ready to pour soon after getting a uniform cream. I'd say within 30 seconds mixed you'd better get it poured. Once it sets it is rigid and easy to cut, if needed. I bought it twice, so I definitely trust it. ## 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-1/2 Gallon Kit - Lifeboat Urethane Pour Foam - 2lb Density - 1 Gallon Kit 2-Part Closed Cell Rigid Pour Foam - Fast-Acting Formula - Great for Boat Buoyancy, Flotation, Filling, Soundproofing, & Insulation - TotalBoat 2 Lb Density Expanding Foam Kit, 2 Part Closed Cell Pourable Polyurethane for Boat Flotation, Insulation, Reinforcement and Void Filling (2 Gallon Kit) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/452735831-liquid-urethane-closed-cell-rigid-pour-foam-2-lb-density](https://www.desertcart.tn/products/452735831-liquid-urethane-closed-cell-rigid-pour-foam-2-lb-density) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-07-04*
