How To Make a Brush‑On Mold Using Dragon Skin™ Silicone Rubber

This mold requires a multi-piece support shell. Begin by planning out where the support shell will split to prevent mechanical lock.
Using a marker, draw a line over the high points of the model along the break points. The support shell will be created in three parts. The back of the model is side 1. The front of the model is split in two parts along the center of the face.

Clay can be used to build shims along the marked high points. Begin by building the clay shim to separate section 1 (back of model) from the other sections. Be careful to build clay on one side of the marked line so that the support shell material can be applied in the planned location. Use sculpting tools to cut keys into the clay shim. Keys will help the support shell lock together tightly when casting. Completed clay shim.
