How to make your own stone walls

Dated: April 18, 2002.

By Ted (Stonewall) Schulz (USA)

Make your own plaster molds for stone walls (or other walls). Use a plastic wall or piece of wall from a model such as a stone fort model. Cut a piece of thick solid cardboard (at least 3/32 inch-2mm thick) to match the piece of wall. A piece of wood could also be used but involves more work. Next, use a WATER BASED wood filler (such as Elmers Carpenter's Wood Filler). DO NOT use hydrocarbon or acetone based fillers (dissolve plastic). Spread a layer of the filler (1/8 inch- 4mm) thick evenly over the surface of the cardboard. Make sure the thickness is uniform and the surface level. Let it sit for a few minutes until a film develops so the plastic won't stick to the filler. Firmly press the plastic wall piece on top of the filler. If it doesn't work correctly the first time, you can repress it a number of times until it's right. Trim the excess filler from the edges. Cut pieces of posicle stick or other thin strong wood to match the lengths of the sides of the cardboard. These side boards can be held on with a weak flexible glue (rubber cement) or just a rubber band. Let the whole thing dry overnight. Paint the wood and filler with a GLOSS enamel paint & let it dry(will keep the plaster from sticking). Fill the mold with mixed plaster of paris and let it set. It's best to leave it for 6-12 hours so the plaster is totally dry and hard. Separate the side boards and carefully pry off the plaster wall section now ready to paint.
