Project Overview & Aesthetic Design
An architectural split design that pairs gritty, industrial gray concrete/jesmonite on one half with glossy white-and-gold marbled resin on the other.
Step-by-Step Execution Guide
-
Create a diagonal dam across a hexagonal silicone mold using craft clay or silicone putty.
-
Pour fast-setting gray concrete or Jesmonite AC100 into one half. Let cure for 2 hours and remove the dam.
-
Seal the cured concrete edge with a thin coat of clear glue or primer to prevent air bubbles from escaping into the resin.
-
Pour white-and-gray marbled epoxy resin into the remaining half of the mold, letting it butt directly against the concrete seam.
-
Drizzle a thin gold vein right along the diagonal seam where concrete meets marble.
-
Torch bubbles and let cure for 24 hours.
Pro Crafter Tip
Always seal the edge of porous concrete before pouring resin against it; unsealed concrete releases trapped air that forms stubborn bubbles along the seam.
