Can I use plaster in the ComposiMold mold?
Great idea. Using a reusable mold material and a very inexpensive mold material (plaster) makes the entire process very low cost. There are no problems with pouring plaster into the ComposiMold. Be sure to use a mold release-Vaseline or vegetable oil may work well for your application or for plaster you can wet the mold slightly and that will work. If you do make something with it, I would love to see what you make. Here is a tutorial on using ComposiMold for Plaster Molds. Or you can see a video of a plaster part being made. You can also use many other mold materials including: -Conrete (I use Quickcrete in the picture below) -Polyurethane -Silicone -Epoxy -Plaster -and probably others.
