How To Handle Large Undercuts In The Brush‑On Mold Making Process
Step 11: Preparing and Casting Smooth‑Cast 300
To cast into the brush-on mold, apply mold release into the rubber mold cavity. Apply the release agent to the rubber exterior and shell (in case of leaks). Align the cut seams of the mold. Assemble the shell segments using rubber bands or mold straps to secure teh mold and support shell for casting. Pour Smooth Cast® 300 into the mold and allow to cure. The finished casting is an exact replica of the original.
