AeroMarine Products Urethane 2 Part Pour Foam, 2# density, 1/2 gallon kit contains:

1 quart of Part A 

and

1 quart of Part B

The total yield of AeroMarine Products Urethane 2 Part Pour Foam 2# Density 1/2 gallon kit is 2 cubic feet, which will float about 120 pounds of dead weight. Our liquid foam expands approximately 20 times its original volume. AeroMarine's polyurethane foam is ideal for adding flotation to a canoe, kayak, jon boat, runabout, or pontoon boat. You can also use it as insulation and soundproofing in a motorhome and in your house. Our pour foam can be poured into the void of concrete blocks to add insulation to a building. Some people use it to stiffen floors under bathtubs or for insulating spas and ice boxes.

To use, mix a small amount of each component together and then pour into whatever cavity you need to fill. Within a few minutes, it will rise and cure. It is resistant to gasoline and oil. You can fiberglass directly over it if you like, although it's not at all necessary. Additional foam can be poured on top of the previous layer every half hour. The foam can be sanded, shaped, or cut easily with a hand saw after it has cured for 24 hours.

Q. How do I clean up foam?
A. Polyurethane foams are very messy and stick to just about everything. Here in our warehouse we use aerosol cans of carburetor cleaner to clean up. Lacquer thinner, xylene, acetone, or toluene will also work. For our hands, we use "Fast Orange" with Pumice. Pour foam does not come out of clothing or shoes.

Q.  Can I paint the liquid foam onto a vertical wall to provide a uniform thickness of insulation foam?
A. No, the liquid foam will just run to the floor, then rise. You will have a big blob of foam on the floor.

Q.  How do I know how much foam I need to float my boat?
A. Great question! Get your calculator ready, you will need it. A cubic foot of foam will float about 60 pounds of "dead weight". The wood parts of your boat should float, so you don't need flotation foam to offset that weight. The fiberglass parts of your boat will barely sink, so you really don't need much foam to offset the fiberglass- maybe one cubic foot of foam per two hundred pounds (or more) of fiberglass hull. The metal parts of your boat are what you really need to account for. A small (4-6hp) outboard may weigh 45-55 pounds. A 50hp outboard will weigh about 200 pounds. 

So a 16 foot fiberglass skiff with a 50 horse outboard will need about six cubic feet of foam to keep it afloat. A 12 foot plastic kayak will only need one cubic foot. A 30 foot fiberglass sailing sloop with a diesel engine and lead keel would need about 150 cubic feet of foam.

Q.  Do I need to paint or fiberglass over the foam?
A. You can, but it's generally not necessary. If you cut into or sand the foam it does need to be sealed with an epoxy or polyester resin because you are opening the cells. Urethane foam can absorb water, when some of the the cells are opened. Painting or glassing will seal the foam and prevent any water absorption. The foam is not UV resistant, so it should be painted if exposed to sunlight.

Q.  Is the urethane foam resistant to fuel, oil, and solvents?
A.  AeroMarine's pour foam is resistant to splashes and miscellaneous contact with gasoline and diesel fuel. A strong solvent such as acetone or toluene would eventually break the foam down, but it would take a long time.

Q.  Can I spray the foam?
A.  NO! We don't sell sprayable foam. Do NOT spray our foam!
