Getting a latex positive (hand) from a silicone negative mold.

edited June 7 in Fabrication
Hi there,
We just cast a hand using Body Double Silk, but have now realized that we need the positive/prop to be made of latex. Since we have a negative silicone mold, what is the easiest way for us to get to a plaster (hydrocal) negative mold to begin skinning with latex?
We were planning on doing a hydrocal positive, and then making a hydrocal neg from that positive, but that's not something I've done before, and I don't know if there's a better way, or anything I need to know to avoid disasters. Does this make sense?

The final piece is a detailed hand cast from an actor, which is larger than my hand.. I'll be wearing it, giving it a look of loose skin, which the actor will be picking at on the palm, until a prosthetic claw pokes through the skin. This is why we decided latex would work better than silicone for the final, as it stretches and tears in a more skin-like way..

Any ideas/thoughts/advice would be very much appreciated.
Thanks!

  • Hi Chris,
    Thanks a lot for the advice. Might look into the urethane foam.
    I haven't tried the latex in the silicone, because I assumed it wouldn't stick, and would bead like you said.. We just cast a stone positive from the mold, so once I take that out, I might try to do a latex one straight from the silicone just in case.. I have a release spray for the silicone that is meant for silicone in silicone, but since you allow the spray to dry, I wonder if it might create enough of a barrier to allow the latex to skin.. I might try that too.

    Thanks again! Super valuable input!
