That said, it will fill cracks as long as you're not depending on it for strength. After it is poured, it will expand. It pours like water so it might be difficult to get it where you want it on vertical walls. Easy to pour on a floor crack but not strong enough to walk on. **Q: What is the flotation range for the 2g kit? will it support 1500 to 2000 lb floating dock?** A: 1 cubic foot of 2 lb. Polyurethane close cell foam will float 60.2 lbs. per US Coast Guard regulations of Flotation. So by the their formula it should float about 480 lbs. of weight. So no you would need 6 2 gallon kits to float just the dock. That's not counting any weight of people that stand on the dock .... **Q: How much does this cover?** A: A two gallon kit (1 gallon resin + 1 gallon activator) will yield 8 cubic feet which is equal to 59.84 gallons. 1 cubic foot equals 7.48 gallons. **Q: Can the 2lb product be used to fill the void in my kayak made of high-density polyethylene or will it deform?** A: It should work just fine. Use a smaller amount at first and then mixed more as needed until the void was filled. I was not not sure how much it would expand so I started with a smaller amount . It expands and hardens quickly. I don't think it will deform your kayak, but it will expand out of any cracks and holes, but you can cut off any foam you don't want. ## Frequently Bought Together - TotalBoat 2 Lb Density Expanding Foam Kit, 2 Part Closed Cell Pourable Polyurethane for Boat Flotation, Insulation, Reinforcement and Void Filling (2 Gallon Kit) - Custom Shop Paint Mixing Cups Plastic Measuring Cup Epoxy Resin, Disposable or Reusable, 32-Ounce Quart - Pack of 12 - Graduated, Mixing Ratios, Automotive Painting Acrylic Art Crafts Kitchen - TCP Global Wood Paint Mixing Sticks - 50 Pack - Automotive, Crafts, Airbrush, Art --- ## 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/23482186-totalboat-2-lb-density-expanding-foam-kit-2-part-closed](https://www.desertcart.tn/products/23482186-totalboat-2-lb-density-expanding-foam-kit-2-part-closed) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-06-06*
