    Not sure if this is the right place to make this inquiry, I have some woodland scenic rock molds, and I am 2 hours from the nearest hobby shop, does anyone have a homemade recipe for plaster that can be used in rock molds? Is there something I can pick up at the local hardware store?

    Thank you:wave: :wave: :thumb:

    Woodyncarlyle, does your local hardware store carry Plaster of Pairs ? Depending on how many and large the molds are will help to determin if you need a bag of plaster rather than the small carton most hobby stores carry.

    Hiya - I use simple premade drywall compound- get the quick drying type. Most hardware stores carry it.

    From the ( good )book "How to build realistic model railroad scenery " by Dave Frary.
    About rocks casting:
    "I'm using the world plaster interchangeably for molding plaster, patching plaster, plaster of Paris and HydroCal. The only significant difference between these materials are hardness and setting time."
    P.S. I use only Hydrocal for rocks casting, so I can't confirm what Mr. Frary says.
