Rock Face Casting Mold
With such a rubber mold you can make beautiful realistic rock formations in no time. Use this mold to make a wall of boulders.
First spray the mold wet and fill it with model plaster, Super Strength Plaster or Lightweight Hydrocal Plaster. When the plaster is hard, remove it from the mold and you can incorporate the rock formation into your mountain landscape. Color the rocks with several layers of diluted acrylic paint. You can reuse the mold dozens of times.
