what materials will release my silicon mold after creating it? Can I create it using cardboard, or will the silicon stick to it? Is wood better? Would acrylic be best? Also can I or should I use mold release in my mold box when creating the mold?

Good Morning Chris,
We sell and use corrugated plastic here, that works really well for building mold boxes. Anything non porous is best, silicone does not bond to anything but itself...however with porous material it has a tendency to wick into the pores. Cardboard is not the best material to use for a mold box.
With Silicone only bonding to itself a mold release for the box (unless of course it was silicone) a release is typically not necessary.
Acrylic is a good material to use, sealed wood, some have used lego's, glad disposable containers (then you don't need to seal the parameters), again anything not silicone or not porous you should be good to use Chris.
Have a great weekend.
Regards,
Carol

I am planning on molding trays for the transport of miniatures of various sizes and shapes using your flexible foam. I can easily make the mold from box from wood. Given that wood is porous, what do you recommend as a wood sealer so the flexible foam will not stick.
The lego option is a good idea, have enough of those in a closet somewhere.

Good Afternoon Russ,
Spray paint the the wood mold box with a high gloss paint to seal the pores. Then you can spray it with the Stoner (silicone) Mold Release, well making sure everything is coated good. The Flexible Foam is a polyurethane, urethane bonds to everything but silicone.
Lego's are often used as a mold box to pour silicone into, as you can configure them for irregular shapes to keep from wasting silicone.
I know what closest of Legos look like!! Have a great day Russ.
Regards,
Carol
