Folders Posted May 24, 2014 Report Posted May 24, 2014 Does jackofoam work as a mold sculpting material? It is pretty easy to manage i mean so that would be nice. Quote
usaeatt2 Posted May 24, 2014 Report Posted May 24, 2014 I've never heard of jackofoam, so I looked it up. It's extruded polystyrene. In the U.S., that material is typically used as house insulation. I've actually carved many things from extruded polystyrene using a hot knife. You can also use expanding urethane foam (like Great Stuff) as an adhesive to stick sheets together. It makes a mess, but it's a nice material for carving. Once you've got your sculptures done, then you could coat it with something to smooth it out, then use it to make a mold. Quote

usaeatt2 Posted May 24, 2014 Report Posted May 24, 2014 (edited) Off topic for this forum, but I carved this guy from EXAPNDED polystyrene (regular styrofoam) for a party. It carves fast and I only spent about 3 days on this project. Extruded polystyrene carves better and you can make more intricate details. I sealed it with StyroSpray hard coating to make it weatherproof and strong (I can stand on it) and he lives at a friend's house next to a swimming pool now. --------------- Edited February 22, 2021 by gmrhodes13 link not working, removed gmrhodes13 2021 Quote
