How To Reproduce a 3D Sculpture Using Brush‑On™ 40 Mold Rubber

Plasti-Paste® is mixed 1 part A to 3 parts B by volume. Mix Parts A and B thoroughly. Apply Plasti-Paste® to the surface of the rubber mold and out to the outer edge of the clay shim. Apply evenly and be sure to build up the outer edges. Plasti-Paste® can hold to a vertical surface unlike any other trowelable plastic available and it also sticks well to itself.

The finished support shell thickness should be 3/8'' or 1 cm. Don't mix more than you can apply in 10 minutes. You can always mix and apply more. Allow the first segment of the Plasti-Paste® shell to cure for 90 minutes. As it becomes rigid, it changes from dark to light in color. After 90 minutes, remove the clay shim from the first part of the Plasti-Paste® support shell.
