is there any way to harden floral foam?
I am making some molds and stuff from floral foam, and I wan't to know if there is a way to harden it and make it heavy. Some of the things I'm making will have to take handling and painting without chipping, breaking, or crushing. I use floral foam because it's easy to use, so I can make models in the first place. I'm not looking for another medium, but how to change it once the model is made. Also, I cannot use anything expensive or that must be bought online. Preferrably something like paper-mache, but that will not stick out from small crevices in the model.
