Product Details

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.

Info & Guides
2-Part Polyurethane Flotation Foam Specifications:
  • 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

Good Test Results

I mixed a small amount of this liquid to observe it the properties of the resulting foam. I was generally impressed. Two ounces of liquid (1 oz. each) resulted in 32 oz (volume) of foam. So a 16:1 expansion ratio. The form was easy to cut and did not absorb water that i could tell.

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.

Bad batches

2 years ago
I bought a two gallon kit of 6lb foam and must have received a bad batch. JD's customer service was great; answered the phone, talked me through it and sent out a new two gallon kit right away. Unfortunately, that batch wasn't much better. I ordered some 8lb foam from another manufacturer to compare, and it was a huge difference. I still have tons of faith in TotalBoat and JD, but I think this line might need some quality control.

Q: How thick is the 2 lb when mixed? Wondering about the viscosity of it, how thin or thick it is when mixed before it starts to expand. What can it be compared to, peanut butter, whipped topping, gravy? Thanks

A: It's not very thick before you mix it. About the thickness of gravy would be my best guess.

Q: Hello. I have a small sailboat similar to a Sunfish that is water logged and weighs a few hundred pounds. I am considering cutting most of the fiberglass deck off and digging out any foam, filling it with your expanding foam and reattaching or refiberglassing the deck back in position. My question is how will this foam stand up to epoxy in repairing the deck? Thanks.

7 months ago
1 Answer

A: You can epoxy over the foam. Commonly boats of that type are not totally filled with foam. They may just have foam blocks glued inside the hull. Before you cut off the deck you may want to drill a drain hole in the transom to see if water can be drained out.

Q: I have a 14 foot fiberglass sailboat with a double hull, that has about 4' of space at the centerboard and tapers down to about 2"" of space at the transom. The beam is 6 feet. I have two questions regarding your 2 pound density flotation foam: Is filling this cavity an appropriate use for the 2 pound product? If some water leaks into the cavity (most eventually have small leaks) what are the consequences of that happening. Approximately how much product do you suggest I order to fill the cavity? Thank you.

1 Answer

A: It might be suitable but more info is needed. Might be worth reaching out to the builder, class association, or online owners group. The foam is closed cell so it should not absorb water.

Q: Hello Community, I hope everyone is doing well. I know this might sound like a crazy idea but I'm currently exploring economical options for DIY outdoor cushions and came across TotalBoat 2-Part Polyurethane Flotation Foam. The product seems promising, with a 94% closed-cell structure for water resistance and available in both 2 lb and 6 lb densities. Has anyone used this particular foam for creating outdoor cushions? I'm particularly interested in knowing about its resilience and ability to return to its original shape after compression. Additionally, any insights into its comfort level and durability when exposed to the elements would be greatly appreciated.

Q: how easy is the 6lb density foam to cut and sand compared to the 2lb density foam I plan to use it to make a buck/plug to make a mold off of. The 2lb foam is very porous and I was thinking that the 6lb density foam would be less porous. Less filling and sanding to get the surface smooth

2 years ago
1 Answer

A: You are correct. That's why it is commonly used for surfboards. However, it does not expand as much as the 2lb foam so you need three 6lb kits to fill the same space as one 2lb kit.

Q: Hi I have a 1992 four winn's 180 freedom I am doing the hole bottom of the boat new floor and stringers and foam my question is what type of foam do I put back in 2lb or 4lb or 6lb. I have all of it out and I am putting back the stringers and bulk heads right now so I have time to get the foam to do it right. thank you for any information on this.

1 Answer

A: The boat probably had 2lb foam in it when it was built. It is your best option as it fills more space than the equivalent sized 6lb foam and it weighs less.

Q: I have a Laser sailboat. The standard flotation is a number of ""cubitainers"" which are just poly air bottles. Mine are missing or damaged. I was thinking of using pour-in foam, since the boat has several hull ports in the deck and footwell which would facilitate the foaming. My concern is waterlogging. The boat will be kept out of the water except when in use. Seems like a good idea, but once done, kinda hard to undo. Am I concerned for no reason? And before someone mentions racing rules, I don't plan to ever sail it in anything other than local regattas.

2 years ago
2 Answers

A: A laser only weighs @ 130 lbs, That means, you only need a little over 2 cubic feet of foam to displace enough water to keep the boat from sinking. My guess is the goal of the cubitainers is to save weight. Foam filling the same space will weigh a bit more. Even though the foam is closed cell it can gradually take on some water over the course of many years, adding some additional weight.

Q: Does this product provide significant thermal insulation?

2 years ago
1 Answer

A: The R-value for TotalBoat Polyurethane Flotation Foam is 6.5-6.6 for 2-pound foam, and 5.0-5.5 for 6-pound foam. The R-value is a measure of a material's ability to insulate, or slow the rate of heat flow. These values are based on 1"" of fully cured foam. The R-value for each foam can be multiplied by the thickness of the foam (in inches) to determine a specific application's R-value.

Q: I have removed the foam core on a 13' Boston Whaler and getting ready to pour the new flotation foam. Should I use the 2lb. or 6lb. flotation foam?

2 years ago
4 Answers

A: I'd like to argue one point here. While buoyancy is defined at the amount of water displaced by the volume, the amount of buoyancy left ""to use"" is reduced by its weight. So if a volume of air displaces 10 lbs of water, you have 10 pounds to use, but if the weight of the foam for the same volume is 2 lbs you have 8 left over, and 6 lbs of foam leaves you with 4 pounds of remaining buoyancy. Having said that the 6 pound formulation is much more dense so should provide a stronger construction. I don't claim any knowlege about the engineering of a Boston Whaler's hull however.
