Select the wall or portal you want to create a mold from.

(You can also build what you want from pieces you already molded)

you can spray with a light coat of Pam cooking spray or Pledge polish.

I have the best results with no spray at all on most items. A spray clear coat or hairspray will seal the surface if the item is porous.

You need a flat ridged surface, a piece of Masonite will work, or a piece of Plexiglas on plywood. Cover it with wax paper. Give it a light mist of spray glue on both sides. Make it at least 2 inches larger then the original piece.

Place the piece face up in the center of the wax paper and press lightly to seal the edges. This will keep the rubber from seeping under and onto the back of the piece.

Use a small nylon fan brush to apply a thin coat of the AMCO liquid latex.

Call 1^st to varify stock, can also be special ordered

Allow 1^st coat to dry overnight. Then apply a thin coat every 6-8 hrs if you can. After 8-10 coats the mold should be ¼" thick. Additional coats can’t hurt.

Important Do not remove the mold Yet!

Remove wax paper and turn over.

Now you must find a small box lid or plastic tray that the mold will fit in easily with at least 1-inch clearance. You can place ¼" risers in the bottom of box to suspend the mold off the bottom.

Mix and pour plaster of paris 1/2" deep in tray. While still soft push Mold with piece still inside evenly into the surface. Then pour more plaster up to the top edge of the mold. Let dry 48 hrs. Gently remove plaster support from tray. Then remove rubber mold & casting together from support. You may need to cut the support to safely remove the mold. Even cut it will still work well for support when placed back in the box.
