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.

- The lightweight, 2 lb. density foam is commonly used for filling voids, filling under decks, and practically any other flotation or insulation application.
- 6 lb. density foam is used for architectural castings, support applications, and has virtually an unlimited number of potential uses.
- The densities shown refer to the weight per cubic foot of expanded foam (12 in. x 12 in. x 12 in.)
- 2 lb. density foam expansion: One 2-Quart Kit expands to approximately 2 cubic ft.; one 2-Gallon Kit expands to approximately 8 cubic ft.
- 6 lb. density foam expansion: One 2-Quart Kit expands to approximately 3/4 cubic ft.; one 2-Gallon Kit expands to approximately 3 cubic ft.
- All expansion rates and times given are temperature critical. Temperatures below 75 degrees F will lower the expansion rate, which will require more foam. The ideal working temperature is 75 to 80 degrees F, or higher.
- Accurate measuring of these products is extremely critical.
- Once fully cured, either foam can be laminated over with any type of polyester, epoxy, or vinyl ester resin without melting. Polyurethane foam is compatible with both epoxy and polyester resin systems.
- This product can be poured in multiple layers, with excellent bonding between layers.
- Working time before foaming: Approximately 45 seconds (2 lb. density) to 65 seconds (6 lb. density).
- Time before full expansion: Approximately 5 minutes
WARNING: The 6 LB. Density Flotation Foam Activator can expose you to chemicals including ethylene glycol, which is known to the State of California to cause birth defects or other reproductive harm. For more information, go to www.P65Warnings.ca.gov

foamed in a oddly shaped holding tank w/ 6lb foam. drill mixer and an infrared thermometer were handy tools to have. make sure everything is at recommended temperature or expansion rate will vary.

I am a Youtube Content Creator and the next project I am working on now is a 1976 Smoker Craft. A complete rebuild. I had purchased other (2 Part-closed cell) products that were twice the cost. Since this is the first time I am using pour foam, I didn't know how much I needed. The folks at Jamestown were awesome the chat with. I will be giving them a "Shout Out" on my channel when I am finished the project.

Used polyurethane Flotation Foam to make a Kayak last summer. Worked out fantastic excellent water craft will provide pics. This year am using it for making light weight strong as heck custom terrariums for keeping small animal's and plants indoors. Really amazing foam if used according to directions there are endless possibilities for application.

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
