AeroMarine Products expanding 2 part pour-in place foam is a closed cell, rigid urethane foam. Our closed cell pour foam works very well as a flotation foam in building and/or repairing boats, barges, docks, canoes, kayaks, pontoons, etc. Additionally, AeroMarine Products’ closed cell pour foam is good for insulating buildings, pools, hot tubs and spas.

Do NOT use our pour foam on inflatables and/or canvas.

**This is a closed cell pour foam only.  It is NOT a sprayable foam!

Always wear a respirator or self-contained breathing apparatus when working with pour foam.

FAQs

Q. I’m making a pontoon boat from empty 55 gallon drums. How much floatation foam do I need?

A. Each 55 gallon drum requires about 8 cubic feet of urethane foam. Since each cubic foot weighs two pounds, you will need 16 pounds of foam per empty drum. Therefore, it will require about one gallon kit (makes two gallons) per drum.

Q. Can I brush or spray 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. It is NOT a sprayable foam.

Q. Is this flotation foam compatible with styrofoam?

A. Yes. It will not “eat” or dissolve styrofoam. If you have a large cavity to fill, you can put some chunks of styrofoam in the cavity to save foam.

Q. How do I know how much foam I need to float my boat?

A. Get your calculator ready, you will need it. A cubic foot of polyurethane will float about 60 pounds of “dead weight”. The wood parts of your boat will probably 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 urethane 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. Actually, very few 30 foot keelboats have positive foam flotation, but it’s not out of the question- especially when you consider all of the air pockets that would exist, as well as all of the wood interior components that provide some positive flotation.

Q. Do I need to paint or fiberglass over the floatation foam?

A. You probably should. Polyurethane will absorb a small amount of water, because some of the the cells are open (95%+ are closed, though). Painting or glassing will seal the foam and prevent any water absorption. However, it really shouldn’t be necessary unless the foam is constantly immersed in water, such as in a boat with bilges that are always wet. The foam is not UV resistant, so it must be painted if exposed to sunlight.

Q. Is the polyurethane foam resistant to fuel, oil, and solvents?
A. Mostly yes. It is resistant to splashes of gasoline and diesel fuel, although it will absorb a small amount because no pourable foam can be guaranteed to be 100% closed cell. A strong solvent such as acetone or toluene would eventually break the foam down, but it would take a long time.

Q. What is the maximum exothermic temperature that cured polyurethane foam can reach?

A. 250 degrees F.

Q. What is the maximum surface temperature that cured polyurethane foam can withstand before it begins degrading?

A. 200 degrees F.  The foam does not ignite. Under high heat and direct flame, it will char like wood. The foam will break down with continued exposure to excessive heat/flame.  The damaged area can be repaired by removing the damaged portion and pouring new foam into the void.

AeroMarine Products' mold making natural liquid latex is one of best liquid latex rubber products on the market. It goes on thicker than any other liquid latex, which gives you a better application and end result! DO NOT USE ON HUMAN SKIN! NOT FOR MAKING MASKS! Our latex mold making rubber is extremely tough, very flexible, and is resistant to tearing. It is brushed directly onto the pattern, allowed to dry, and then reapplied. This process is continued until the latex mold has reached the desired thickness. When dried, AeroMarine Products' latex rubber resembles a rubber band. You can remove it from the original by rolling it up like a sock. Latex is best for making molds for casting cement, concrete, plaster, hydrocal, or hydrostone. It can be used for limited runs of resin castings, but the yield is low. Tips: Latex "air dries", like paint, but much thicker. To speed up the drying process, you can use a heat gun to blow warn dry air over the freshly applied latex. Cheesecloth makes a good reinforcement for a latex mold.  After brushing on at least 4 coats of latex, add some cheesecloth to reinforce the mold. Since it is so flexible, you may want to put the latex mold into a bed of sand so that the mold does not distort when being filled. When storing your latex mold, leave a casting in it to help the mold to preserve its shape. To make your latex thicker and to reduce the cost of making a mold, consider adding our black rubber powder. This product is made from reclaimed rubber tires! If you must thin latex, distilled water is preferred, although tap water seems to work. Thinning latex is not recommended because it slows the process and increases shrinkage.  **Always wear a respirator or self –contained breathing apparatus when working with urethanes.** Do NOT spray.  Our urethanes are only for pouring applications.

AeroMarine Products Polymer Urethane Black Super Fast Casting Resin is a very fast setting, 1:1 mix low odor, " almost water thin" system. Our Urethane Balck Casting Resin is great for casting decorative figurines, picture frames, and industrial parts. It has a 1 minute work life, so you make certain that you have your mold ready before you begin pouring and mixing the Black Casting Resin. With a 15 to 30 minute demold time, you can make rapid prototypes or production runs. It has a 1:1 mix ratio by volume AeroMarine Polymer Urethane Black Super Fast Casting Resin is a deep black color.  It sets to a hard polymer form and is very tough and impact resistant. Our Black Casting Resin somewhat resembles PVC pipe when cured. Shrinkage is usually unmeasurable.  We sell an aerosol urethane mold release for use with this casting resin. NOTE: Make sure that the casting resin, tools, containers and ambient temperature are all at 70F before you begin pouring and mixing the casting resin. If you do not have everything at 70F, the casting resin will take much longer to cure. Also, at temperatures higher than 72F, the casting resin will cure faster. Specifications:
