Bran new to molding so please bare with. attempted to demold my plaster mold and I had to chisel it apart. I sealed the molds with two coats of clear gloss. waxed two coats with Johnsons one step floor wax, ??? After everything was dry, I sprayed them down with syn-lube, ??? let that dry, then foamed it. obviously not the right procedure, because the foam stuck to the plaster mold. Will candle wax work as a separator? Can I put a thin layer of nonhardening clay inside the mold and foam it, will it foam properly inside the clay? My final casts will be covered in clay anyway before I make the fiberglass molds. Glad I only foamed one mold for a tester. Molding gurus, let me have it! Thanks in advance!
