Step 9Prepare the Box Mold

Prepare the Box Mold
Apply 2-3 coats of shellac with a brush to the interior of the box to seal it, letting each coat dry before applying the next.

Seal any gaps at the corners of the box or where the base meets the walls, with an oil-based, sulphur-free clay that won't react with the rubber you'll be using (such as Prima Plastilina).

Attach the sealed plaster part to the bottom of the box with a piece of clay.

Spray the interior of the box thoroughly, including the plaster piece, with a release agent (such as Pol-Ease 2300). Be sure to get all of the corners, undercuts, and other places rubber might find a place to steathily stick to.
