You Will Need: Shell Shock® Brushable Plastic, Skin Tite®, Silc-Pig®, Ease Release® 200, Non-Sulphur Clay, Melamine Board, Mixing Sticks and Containers, Paint Brush, Baby Powder

Step 1: Designing Wound

Create a sculpture of desired wound in non-sulphur clay, then apply Ease Release 200 to the entire surface.

Step 2: Measuring Shell Shock™

Measure Shell Shock™ Parts A and B separately (1A:5B by weight), and then combine and mix thoroughly.

Step 3: Applying Shell Shock™ To Sculpture

First, apply a thin detail coat of Shell Shock™ by stippling it onto the clay sculpture. After the first layer, mix, measure, and apply a second thicker batch of Shell Shock™. Repeat once more for a third batch, creating 3/8'' (1cm) mold thickness.

Step 4: Demold

Remove the Shell Shock™ mold from the board and clear the excess clay out of the mold using a wooden stick.

Step 5: Measure Skin Tite™

After the edges of the mold are sanded smooth, measure Skin Tite™ parts A and B separately (1A:1B by volume). Add Silc-Pig™ flesh tone pigment to Skin Tite™ part B and to Skin Tite™ part A. Mix the Skin Tite™ silicone thoroughly for a perfect wound make-up effect.

Step 6: Casting and Demolding Skin Tite™ From Mold

Spread the mixed Skin Tite™ into the mold using a wodden stick and scrape the excess Skin Tite™ away. After a 10-minute cure, powder the Skin Tite™ piece and carefully remove it from the Shell Shock™ mold.

Step 7: Applying Skin Tite™

The Skin Tite™ wound make up appliance is now ready for application. Mix Skin Tite™ and apply it to the model's skin. Then, mix more Skin Tite™ and use it to blend the edges of the piece. After the Skin Tite™ cures, apply theatrical makeup for a fake blood effect. The finished piece bends and flexes with the model's facial movements.
