Bubble Buster is a PVA mixture that reduces bubble formation when making your mold. It works by reducing the surface tension so the bubbles rise up and away from the mold surface.
- Spray a thorough coating of 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.
