Resin Art Tutorial: Sculpture Resin Cast & Finish

Summary of the Resin Art Process (from the subtitles)

The video demonstrates how to cast a small figurine/sculpture from a silicone matrix mold using a fast polyurethane resin. It then shows quick demolding and simple surface finishing to achieve two effects:

• A green “oxidized copper” look (on the second cast)
• An antiqued stone/wax patina appearance (from wax finishing)

Artistic Techniques and Creative Processes Shown

1) Resin casting with a silicone matrix mold

• Uses an existing silicone matrix mold (made in a prior tutorial) to produce a figurine “copy.”
• Emphasizes mold orientation so the sculpt’s facial details point correctly during pouring.

Pouring approach to reduce defects

• Tilt the mold to help trapped air bubbles rise—especially around the face/nose.
• Tap/jostle the mold so bubbles travel up toward the surface.

Resin mix/casting method

• 1:1 mix by volume of components (TC 802).
• The resin is fast-setting, so mixing and pouring must happen quickly.
• Mix time noted: ~25–30 seconds for thorough mixing.
• No pressure casting is needed due to low viscosity and the pouring technique.

Monitoring cure readiness

• The remaining resin in the cup changes color to white as it cures.
• Demolding guidance: typically 10–15 minutes, depending on thickness.
• Polyurethane cures in an “inverse” way compared to air-dry products:
  • Thinnest areas cure last
  • Demold only after those sections are firm

2) Mold design for easier production (seamless mold / mother mold system)

• Uses a seamless mold strategy to reduce cleanup on the finished sculpture.
• Mold system components mentioned:
  • Platinum silicone matrix mold: TC-5110F
  • BR75D mother mold to support/reuse the matrix for repeated casting
• Demonstrates reorienting/reassembling the mold and casting another copy.

3) Pigmented cast to simulate oxidized copper

• Cast #2 is colored with green pigment to create a pastel green effect.
  • This accounts for the fact that the base resin turns white during cure.

Pigment workflow

• Green pigment is mixed into Component B only (to save time and avoid wasting effort suspending pigment in both components).
• Reaction timing reminder:
  • The process starts only after Component A is added
  • Mixing must be efficient and timed

4) Simple finishing methods (paint/wax)

Green cast finishing

• Uses dry brushing metallic paint (Sculpt Nuvo copper) over high points.
• Dry brushing helps emphasize sculpt details and reinforces the “oxidized copper” illusion.

White cast finishing

• Applies Sculpt Nuvo brown wax across the entire piece.
• Method:
  • Stippling to apply wax
  • Then quickly wipe with clean paper towels to shape the effect
• Timing emphasis:
  • Wipe quickly before it fully cures/“grabs,” or removal becomes difficult
• The remaining wax creates an antiqued/aged stone appearance.
• Optional follow-up mentioned (not required for the demo):
  • Clear sealer
  • Additional metallic colors
  • Additional wax finishing

Step-by-Step Casting & Finishing Workflow (as shown)

Casting (TC 802, 1:1 by volume)

1. Prepare the silicone matrix mold inside the mother mold (ensure correct orientation).
2. Mix resin (TC 802) components:
   • 1:1 mix by volume
   • Mix thoroughly for ~25–30 seconds
3. Pour resin into the mold:
   • Partially fill first
   • Tilt the mold so the sculpt face/nose direction is correct
   • Tap/jostle to help bubbles reach the surface
4. Top off the mold to fill completely.
5. Demold timing:
   • Watch the resin in the mixing cup: it turns white as it cures
   • Typical demold time: 10–15 minutes (depends on thickness)
   • Be especially patient for thin areas (these cure last)

Pigmented cast (green)

1. Mix green pigment into Component B only.
2. Add Component A and mix quickly (reaction begins once A is added).
3. Pour promptly into the mold:
   • Tilt/jostle to prevent bubbles on fine facial details (notably around the nose tip area)
4. Demold after cure (around 15 minutes indicated).

---

Finishing

Green cast

• Dry brush copper metallic paint on raised/high-detail areas.

Plain white cast

1. Apply brown wax with stippling.
2. Immediately wipe off excess wax using clean paper towels.
3. Leave enough wax behind to create an antiqued/aged texture.
