Is It Safe to Use All 3 kg at Once?

Why Layering Is Important

Epoxy resin generates heat as it cures—a process known as an exothermic reaction. Pouring a huge amount, like 3 kg, into a single mould can result in excessive heat, leading to issues such as discolouration, bubbles or even cracks. For most clear epoxy formulas, it’s advisable to pour in layers, letting each one cure before adding the next. This controlled process prevents overheating and ensures a reliable finish.

Recommended Pour Depths and Techniques

Always check your resin’s guidelines regarding maximum pour depth. Products such as EpoxyTable 5-Five allow you to pour up to 5cm deep in one go, making it suitable for large furniture projects. For resins like “Trasparente”, stick to thinner layers of up to 2cm—allowing each to partially cure before the next. Waiting 6–8 hours between pours encourages strong bonding and clear, bubble-free results.

• Always split large volumes over several pours
• Pour each new layer after the previous one reaches a gel stage
• Follow specific product instructions carefully

When This Matters Most

Layering is especially crucial when working on thick or large projects, such as river tables, encapsulations, or deep castings. If you’re aiming for exceptional clarity and durability, patience pays off—rushing the job or exceeding recommended thickness puts your project at risk.
