5. Apply a mold release to the ComposiMold mold.

6. Mix your resin, if using ComposiCast Urethane Resin, mix in equal parts by weight or volume.

7. Pour the resin into your ComposiMold Mold. (Note: Larger parts can be cast by cooling the ComposiMold in the refrigerator or freezer prior to pouring in the resin.)

More information about applying Mold Release to your Model:
Applying a mold release (or release agent) will allow your model to be easily separated from the ComposiMold. Applying a mold release to the mold before casting will also minimizes wear and tear on the mold. This is important if you are using the mold to make many reproductions.
