Is expanding foam flammable when cured?

Once the foam is sprayed from the can, it immediately begins to cure and dry into a hard plastic. It sticks permanently to most surfaces, including skin. The can contains a quick reacting hazardous chemical, isocyanate, to form the non-hazardous plastic, and a highly flammable gas to force the product out of the can.

Can you use expanding foam in the rain?

Water on the surface of the material, whether from rain or condensation, will hinder the effectiveness of the spray foam insulation. It will essentially prevent it from sticking properly. Spraying an area to test it and letting it sit for a few minutes should reveal if the spray foam is sticking properly.
