Best Resin Thickness for Metal Inserts

Recommended Resin Thickness for Metal Inserts

For secure embedding, aim to completely cover the insert with at least 2–3 mm of resin above and around it. This helps prevent metal protrusions, avoids weak spots, and creates a smooth surface. In large projects such as deep pour tables, the resin can be much thicker, but avoid exceeding the manufacturer’s suggested single-pour depth to minimise overheating risks.

• Small-scale or jewellery projects: 2–3 mm coverage is typically sufficient.
• Larger castings: Layer the resin according to your chosen product’s maximum recommended thickness.

Product Choices by Project Size

Select your resin according to the scale of your project and the required depth. For example, “Trasparente” multipurpose clear epoxy is suitable for layers up to 2 cm, making it a great choice for craft and small art pieces. For deeper projects, such as tables with thick or embedded metal parts, consider EpoxyTable 5-Five (up to 5 cm per pour) or Epoxytable 10-Ten (up to 10 cm per pour). Always allow sufficient curing time between layers if your project exceeds the advised thickness.

When Does Resin Thickness Matter Most?

Thickness is especially important when embedding heavy or large metal inserts (such as table legs or hardware), where insufficient resin coverage can weaken the piece. Proper thickness also reduces the chance of cloudiness or trapped air bubbles, leading to better clarity and durability in all types of resin projects.
