Hey everyone I have a question I'm about to make a set of slip molds again to pour small statues, I have made the molds over and over,each time varying depending on how much detail is left the the castings,. Is their a way to strengthen the plaster molds so they can have a long run of castings made in them before they loose all of the castings details,,,,,I thought about adding glue to the plaster but this will reck the moisture absorbsion ??? What can I do any suggestions would be greatly appreciated
