How to Corpse a Plastic Skeleton

Corpsing is the process of transforming a clean plastic skeleton into one that appears to have dried skin, mummified tissue, or decayed remains. Using layers of plastic and controlled heat creates an incredibly realistic texture that's perfect for haunted houses, Halloween displays, or horror props.

 

Materials

• Plastic skeleton
• Plastic grocery bags
• Plastic painter's drop cloth or plastic wrap
• Heat gun
• Scissors
• Spray adhesive (optional)
• Acrylic or spray paints
• Clear matte sealer (optional)

 

 

Step 1: Prepare the Skeleton

Start with a clean plastic skeleton and remove any tags, stickers, or accessories.

Decide which areas you want to have exposed bone and which areas will appear to have dried flesh. Planning ahead helps create a more realistic final result.

 

Step 2: Apply the Plastic

Begin wrapping sections of the skeleton with thin plastic.

Use a combination of:

• Flat sheets for larger areas
• Twisted strands for tendons and muscles
• Loose, wrinkled pieces for rotted skin
• Thin strips wrapped around limbs

Don't wrap everything the same way. Natural-looking variation is what makes the effect convincing.

Layer different types of plastic in different directions. Let pieces overlap, bunch together, and hang loose in places to create depth and texture.

Tip: Grocery bags, painter's plastic, and plastic wrap all shrink differently when heated. Mixing them together creates more interesting textures.

 

Step 3: Build Up Layers

Continue adding additional layers anywhere you want thicker tissue.

Good places to build texture include:

• Rib cage
• Shoulders
• Pelvis
• Neck
• Hands
• Feet

Leave some bone exposed while heavily wrapping other areas. This contrast helps sell the illusion of decomposing flesh.

 

 

Step 4: Shrink the Plastic

Using a heat gun on a low setting, gently heat the plastic.

Keep the heat gun moving constantly and work a small area at a time.

As the plastic shrinks, it will tighten around the skeleton and create wrinkled, organic-looking skin.

Be patient. Several light passes work much better than one long pass.

Warning: Too much heat can permanently warp or melt the plastic skeleton. If the plastic begins to gloss over or deform quickly, back away and allow it to cool before continuing.

 

Step 5: Refine the Texture

After shrinking the first layers, you can continue adding more plastic and heating again.

Alternating between adding plastic and shrinking it creates thicker, more complex textures that resemble dried muscle and connective tissue.

Don't aim for perfection. Uneven areas, folds, holes, and stretched plastic often look the most realistic.

Step 6: Paint the Corpse

Once you're happy with the texture, paint the entire skeleton.

Choose colors based on the look you're after:

• Fresh Corpse: Reds, dark browns, purples, and gloss clear coat for wet blood.
• Old Corpse: Browns, tans, faded reds, and muted grays.
• Mummified: Light browns, tans, and dusty beige.
• Dirty Skeleton: Black and dark brown washes with dry brushing to highlight details.
• Burned Corpse: Charcoal black, gray, and dark brown with subtle ash highlights.

Apply darker colors into the recesses and dry brush lighter colors over raised textures to emphasize the detail created by the plastic.

 

Step 7: Seal (Optional)

If the prop will be displayed outdoors or handled frequently, finish it with a matte clear coat to help protect the paint.

If you want wet-looking gore, apply a gloss clear coat only to the bloody areas.

 

 

Tips

• Less is more—leave some bone exposed to create visual contrast.
• Mix different plastic types and wrapping styles for the most natural appearance.
• Twist plastic into rope-like strands to simulate tendons and dried muscle fibers.
• Build texture gradually instead of trying to achieve the final look in one layer.
• Always test your heat gun on a hidden area first to learn how your particular skeleton reacts.
