## Description

Be safer and more comfortable on your boat with Total Boat Two Part Polyurethane Marine Expanding Foam. This US Coast Guard compliant pour foam is commonly used to add buoyancy to keep a boat afloat if hull integrity is compromised. Its closed cell foam structure enables it to resist water absorption for many years, making it ideal for filling pontoons and cavities in kayaks and beneath boat decks. 2 Lb. density expanding urethane foam kit mixes to form a fast-setting, pourable liquid foam that cures to a rigid, lightweight material that's also great for filling gaps, soundproofing, and providing thermal foam insulation and nonstructural support in a variety of marine, household and art applications.Two part flotation foam has a simple 1:1 mix ratio that makes it easy to use. Warm conditions of 75-85°F are very important, as are accurate measuring, thorough mixing, and proper venting of the area where the foam is to be applied, because it expands tremendously by volume. Just mix one part resin and one part activator, stir vigorously for about 25 seconds to mix completely and pour immediately into the prepared area. Expanding foam will distribute itself evenly - even into irregularly shaped areas. Cured foam hardens into shape, with minimal shrinkage, and can be cut to shape easily. Once fully cured, any areas exposed to sunlight should be laminated or painted over with polyester, epoxy or vinyl ester coatings. For best results filling larger areas, pour in multiple layers to allow proper cure and maximum strength bonding between layers. Always wear proper eye, face and clothing protection when you mix and pour two part marine foam.Compare to Evercoat Marine Foam-It, FGCI Polyurethane Foam, Polymer Planet Liquid Urethane Foam, Morris Materials Urethane Pour Foam, True Composites Pour Foam, and System Three Flotation Foam for boats. All TotalBoat products provide great value and great results. 100% made in the USA.

- EASY TO USE: Liquid urethane pour foam has a simple 1:1 mix ratio, expands rapidly & hardens in place in about 5 min. at 70-80°F; to build multiple layers for filling under boat decks, pour expanding foam in separate batches
- 94% CLOSED CELL FOAM: Perfect for marine applications; resists water absorption and damage from gas, oil or solvents; once cured, foam can be coated with polyester, epoxy or vinyl ester resin; can also be easily cut or carved to shape
- IDEAL WORKING TEMPERATURE IS 75-85°F; proper temperature, timing, mixing and venting are critical for proper foam expansion; below 75°F expansion decreases; after mixing, the foam expands rapidly and becomes rigid, so clean the surface in advance and be ready to pour

## Questions & Answers

**Q: Can you use on basement cracks**
A: The foam is made to fill voids in boats for flotation and is not structurally strong.
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.
