Mold Release for Molds and Casts


Mold Release for Molds and Casts

1. Applying a mold release to your original object will allow it to be easily separated from the ComposiMold. 2. 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.

Applying Mold Release to your Original Object When Making Your Mold:

Mold Release

  • Spray a light mist coating of Mold Release over the entire surface of the original object and all surfaces of your mold box (and any surface that will come in contact with the ComposiMold). You can also use a clean paint brush or cloth to apply the mold release. Make sure that intricate details, undercuts and hard to reach areas are coated as thoroughly as possible.



  • Wipe off any excess mold release to make sure you do not have too much.


  • Bubble Buster
  • Spray a thorough coating of our Bubble Buster to your original object over the mold release. Make sure that intricate details, undercuts and hard to reach areas are coated as thoroughly as possible. Bubble Buster is useful when making your mold as it reduces bubble formation in the ComposiMold.



  • Continue with your mold making process by pouring the melted ComposiMold over your original object. See the basic instructions on our How it Works Page.


  • Applying Mold Release to your ComposiMold When Making Your Casts:


  • Spray a light mist coating into the entire cavity of your ComposiMold. You can also use a clean paint brush or cloth to brush the release agent into the cavity of the mold. Make sure that intricate details, undercuts and hard to reach areas are coated as thoroughly as possible.



  • Continue with your casting process by pouring or pushing your casting material into your mold per product instructions. See the basic instructions on our How it Works Page.


  • Do you need a special mold release when molding with ComposiMold?

    We sell a Silicone Mold Release that works well for mold making and casting, but many other mold releases also work well. Vegetable oil as a mold release is a perfect food safe option.

    Try these options as a mold release as well:


  • Petroleum jelly (Vaseline)


  • Cooking Spray


  • Mineral Oil


  • Soap


  • Motor Oil


  • Spray Lubricants (WD40, ArmorAll)

  • The best bet for determining the effectiveness of a specific mold release is to experiment. With ComposiMold you can!
