Can i make a silicon(rebound smoothon) mold of a allready finished plaster/
hydrocal cast; to reproduce an exact copy.
Any tips how to do this succesfully. I tried once and the first layer of the cast came of. Maybe is should have let it dry first a week or so.
Thank you

Shouldn't have problems taking a silicone mold from a plaster. With silicone the plaster doesn't neccessarily need to be dry but wouldn't hurt. It does need to be sealed, ei. Krystal Clear acrylic spry, or 3-4 layers of a paste/floor wax, etc. Being silicone, it shouldn't need a release once the plaster is sealed. Just be aware that Platinum bases silicones are sensitive to some chemicals and won't set up correctly around said materials.
