Mix TotalBoat 2-Part Polyurethane Flotation Foam in equal parts and pour in place to soundproof, insulate, provide buoyancy, and even create art. Pourable foam has 94% closed-cell structure to resist absorbing water, and is unaffected by gas or oil. Available in 2 lb & 6 lb density.
2 pound density foam is great for filling voids in non-structural applications. Can be poured beneath decks and inside cavities to provide buoyancy, and has a flotation range of 75 lbs/qt and 300 lbs/gal.
6 pound density foam has higher compressive strength, ideal for filling cavities to support heavy loads. Its smaller cell structure makes it a popular choice for uses ranging from buoys to sculptures. Its flotation range is 23 lbs/qt and 92 lbs/gal.
Both have been tested in accordance with U.S. Coast Guard Regulation # 33 CFR 183.114.
Available in 2-Quart and 2-Gallon Kits.

Minor comment: The cans are labeled as net contents 1 Qt. Not quite sure what "net contents" means but contents are definitely less than one liquid quart. However, as long as contents are mixed as directed (1 to 1), the end results are perfect. :-)

Using it to rebuild flooring in 1970 Correct Craft Freeport. Correct Craft made liberal use of foam to support the floor in addition to wood. Kept a lot of the old foam, but had to discard some of it that was too saturated with water. When cured it is extremely solid, yet easy to cut and shape to a fair surface.

Bought to fill the walls between my freestanding tub. Was a bit nervous about the pressure busting the walls or heating up too much, but it worked perfectly. Highly recommend everyone doing this for their tub, gets rid of the hollow sound and holds warmth.

I used it to make blocks for flotation using plastic containers for my boat. I used cardboard cup holders to prevent spills and red cups to pour equal amounts of material. I also labeled each cup A or B. Outside temperature 75/80 degrees. I was able to coax each block out after a half hour. I used blocks instead of poring directly into my aluminum boat with marine wood as my floor, because it took long time to take out saturated foam. Using a crow bar to pry out material was very helpful. Additionally, I used noodle rod foam to secure blocks. These tips helped me as I was able to access bad foam. Marine repairman told me fiberglass boats also can get foam saturated with water. My boat is 12 years old and stays in water for about 4 months. I use bilge pump to help rid water.

Used to build composite panels for a diy truck camper. Lots of variables affect expansion, so it is not super consistent density, but it works as advertised

Flotation Foam worked good to replace the original flotation in the bow and stern of a 1970 aluminum canoe. The 80 lb canoe is now unsinkable.

Easy to use. Just take the time to measure the cavity you are filling and the right amount of the mix to minimize waste. Also, you must wear a respirator when using this product.
