Next a clay wall is built around the mold. This will allow Justin to pour in the plaster over the sculpt to create the top half of the mold.
The first coat is called a splash coat, it's thinner than the rest of the coats, about the consistency of a heavy cream.
Once the splash coat is added, a heavier mixed coat is applied, about the consistency of pancake batter.
Next, sheets of burlap are dipped into plaster and criss-crossed onto the next layer. This will make the overall mold much stronger.
After the burlap sheets are added a final coat of plaster is applied, again mixed to the consistency of pancake batter.
Once the final coat is applied, the clay wall can be removed. The plaster has already started to set and harden.
The plaster is then burnished with piece of burlap. Also any ridges and bumps of plaster are removed. This makes the mold much smoother and cleaner and also eliminates any sharp corners that can cut you later!
