Silicone mold making using styrofoam form

Recommended Posts

Hello Meka, when you say "intended shaped mold" what are you referring to? Do you want to use it as the mold box, and pour silicone into it, or are you intending to actually carve a form out of styrofoam?

I've not used silicone but  have used urethane rubber.  As long as I coat non-porous objects with silicone spray I've had no problem with sticking.
