polyurethane and others. some are based Petro steam, while others are not. if you have no experience with the sticky, sprinkle a little bit and let the foam for a time as it expands to 50 times or more. put too much on the walls and the panel appears gypsum, plaster, stucco, paneling, tiles. Fumey to matter, not light matches or IGC, or barbecue, or expect a loud noise, loss of facial hair, a big fire not easy to extinguish, and other problems of the residents, the owner, the fire department, spouses, children, and a large repair bill to replace all the damaged material, sometimes windows.
