Deep Pour Casting: Which Epoxy Resin Is Best for Thick Layers?

Q: When Deep Pour Matters

River tables: Achieving a seamless, glassy effect across wide and thick areas. Large-scale art: Filling deep voids in wood art or sculpture bases with brilliant clarity. Robust surface strength: Thick layers result in durable, abrasion-resistant pieces suited for heavy use.

Deep Pour Casting: Choosing and Using Epoxy Resin for Extra-Thick Projects

Deep pour casting allows you to create substantial, dramatic resin layers for river tables, furniture, and complex art pieces. Success hinges on choosing the right epoxy formulation for your project’s thickness and size.

Choosing the Right Resin for Deep Pours

For deep pour projects with layers up to 10cm in thickness, a specialised resin is crucial to control heat buildup and prevent bubbles or cracks. Epoxytable 10-Ten is specifically designed for large tabletops and artistic castings in this range, thanks to its low exothermic reaction and slow curing. For smaller deep casts between 2cm and 5cm, opt for EpoxyTable 5-Five, which delivers excellent clarity and mechanical resistance without the risks of overheating. If your casting is thinner than 2cm, a conventional coating resin like Icrystal is sufficient.

Working Techniques for Deep Pour Epoxy

Proper preparation ensures the best outcome for deep pours. Always pour in a controlled environment to minimise dust and temperature fluctuations. Pouring thicker than the product’s rated depth can lead to overheating and defects, so follow manufacturer guidelines strictly—consider multiple layers if your project exceeds recommendations. Allow each layer to cure fully before adding the next. Take your time with mixing and degassing to avoid introducing air bubbles, and use moulds suited for high-thickness resin applications.
