Mold Builder is a liquid latex rubber which air dries. Can be used for making molds for casting wax, plaster, lay-up resin or Artificial Water. It is also great for casting soft flexible parts from plaster molds (such as an original open mouth insert). Simply paint a layer of Mold Builder on the surface of your plaster mold, allow to dry, and repeat to thicken.
