FAQs

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

A. Yes. Polyurethane can absorb a small amount of water, if the material gets punctured or the cells are damaged. Painting or glassing will seal the foam and prevent any water absorption. 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. It is resistant to splashes of gasoline, diesel fuel, oils, and other similar chemicals. A strong solvent such as acetone or toluene will eventually break the foam down.

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.
