How to Pour Resin in Controlled Layers

Why Layered Pours Matter

Casting resin too thickly in one go often leads to overheating and air bubbles. Epoxy resins naturally generate heat as they cure, and excessive depth can cause the mix to cure too quickly or even crack. By dividing your total depth into separate layers, you maintain better control over the curing process and achieve crystal-clear, uniform results—especially important when working with wood, which may trap pockets of air.

How to Pour in Layers

• Choose a suitable resin: For pours up to 2cm, a multipurpose clear epoxy such as Trasparente is ideal. For castings up to 10cm deep, opt for a dedicated deep pour resin like Epoxytable 10-Ten, pouring in increments if your piece exceeds the recommended limits.
• Plan your layers: Pour the first layer and allow it to partially cure (usually until tacky) before adding the next. This helps each section bond securely and minimises the risk of visible lines between layers.
• Minimise bubbles: After each pour, use a heat gun or a torch briefly to remove surface bubbles, taking care not to overheat the resin. Cover your work to prevent dust settling while it cures.
• Monitor timing: Pour subsequent layers at the right stage—not too soon to avoid mixing, not too late to ensure good adhesion.

When Pouring in Layers Matters Most

This method is crucial for larger resin and wood tables, river tables, memorial jewellery, and whenever you need thick, clear resin sections without flaws. If your project exceeds the safe pour thickness (typically 2cm for standard resin or 10cm for deep pour formulas), always use controlled, layered pours for best results.
