๐Ÿ”€ How Does It Compare?

vs Plaster: Harder, more durable, less brittle, better detail. Handles drops better.

vs Epoxy Resin: No fumes, no two-part chemistry, water-based. Easier cleanup, safer indoors.

โœ… Pros

  • Single component โ€“ just add water
  • Non-toxic, no harsh fumes
  • Excellent detail capture
  • Harder than plaster, ceramic feel
  • Fast demould (~30 min)
  • Zero shrinkage
  • Safe for silicone moulds

โš ๏ธ Keep in Mind

  • Thin/long pieces can be fragile โ€“ reinforce with wire if needed
  • Ratio matters โ€“ measure carefully
  • Too much water weakens cast
  • Full strength needs 24hr cure

๐Ÿ’ก Pro Tip

For complex moulds, brush a thin layer of mixed resin into the details first, then pour the rest. Helps prevent air pockets and ensures crisp detail capture.

โœ“ Safety: Non-toxic, odourless, water-based. No special ventilation required. Age 14+. Wash hands after use. Not for food contact.
