Casting Epoxy Resin Up to 5cm Thick

Q: Best Practice for Deep Pours

Prepare the Work Area: Work in a dust-free, temperature-controlled space to ensure a smooth finish and proper curing. Mix Thoroughly: Measure and blend components according to the instructions—undermixing can result in soft patches or poorly cured resin. Pour in Stages if Needed: For very large projects or when pouring over 8kg of resin, cast in layers to allow each to gel before adding the next. This reduces risk of overheating. De-bubble: Use a heat gun or torch gently after pouring to help release surface bubbles, ensuring a clear result.

Castings Up to 5cm Thick with Epoxy Resin

Achieving crystal clear castings up to 5cm thick requires the right choice of epoxy resin and sound pouring techniques. This guide covers the basics for successful deep casting with epoxy, so your project cures both strong and transparent.

Picking the Right Epoxy for 5cm Castings

Not all resins are formulated for thicker layers. For deep pours up to 5cm thick, a low-exothermic epoxy such as EpoxyTable 5-Five is recommended. This specialist resin is designed to cure slowly to reduce heat build-up, preventing cracks or yellowing in your casting. It also features strong UV filters for long-term clarity and a tough, scratch-resistant finish.

When Thick Castings Matter

Epoxy castings of up to 5cm are ideal for making river tables, encapsulating objects, or creating furniture pieces where substantial thickness is needed for visual impact and strength. Specialist deep pour resins like EpoxyTable 5-Five are formulated for these ambitious projects, enabling lasting clarity and durability.
