Smooth-OnÕs FOAM-iT!¨ Series consists of two-component rigid foams that are versatile and easy to use. FOAM-iT!¨ products are available in 3lb., 5 lb., 8 lb., 10 lb.,15 lb. or 26 lb. per cubic foot densities. Parts A and B are measured and mixed in equal amounts by volume (Note: FOAM-iT!¨ 8 is measured and mixed 2A:1B by weight). The mixture is then poured into a mold or other form (apply release agent if necessary). The mixture will expand many times original volume (depending on which FOAM-iT!¨ product you are using) and develop a uniform cell structure.
