Avoid Pouring Too Thickly to Prevent Overheating

Why Too-Thick Resin Layers Overheat

Epoxy resin cures via a chemical reaction that generates heat. Pouring deeply in one go—especially more than 2cm at a time—traps more of this heat inside the resin. This excessive warmth can discolour the resin, create bubbles, distort your cast, or even lead to cracks. Following manufacturer recommendations is crucial to control this reaction and get a clear, strong finish.

Tips For Safe, Even Pours

• Layering: Pour in several shallow layers, each no thicker than advised—such as up to 2cm when using Trasparente multipurpose resin.
• Allow for Cool Down: Let each layer cure and cool before adding the next.
• Accurate Dosing: Use a precise measuring tool like the 2L Graduated Measuring Cup to ensure the correct ratio and amount for each layer.
• Temperature Control: Work in a moderate environment and follow the instructions for your chosen resin.

When This Matters

Overheating is especially important for large castings, jewellery embedding, tabletops, and clear artistic projects where clarity and structural integrity count. Even experienced makers should take care whenever using substantial volumes of resin.
