Best Resin Choice for Thick Casting & River Tables

Choosing the correct resin is key to achieving clear, bubble-free results in thick castings or river tables. The right product ensures both structural integrity and visual appeal for your large-scale resin projects.

Deep Casting Resin: Key Differences

Not all epoxy resins are suitable for thick pours. Regular resins may overheat or crack when used in layers above 1–2 cm. Dedicated deep-pour resins, however, are formulated with low exothermic reactions to allow single casts of several centimetres. For example, EpoxyTable 5-Five is ideal for pours up to 5 cm, while Epoxytable 10-Ten handles depths up to 10 cm, making them the preferred choices for river tables and significant artistic castings.

Practical Tips for Thick Resin Castings

Always follow manufacturer guidance on maximum single pour depths.
For very large projects (side over 100 cm or weight over 8 kg), cast in multiple layers, waiting 6–8 hours between pours, to reduce risk of heat build-up.
Allow plenty of working time and ensure your workspace is at a stable temperature for best results.
Choose resins with low viscosity to help bubbles escape during curing and look for strong UV protection to prevent yellowing over the years.

When Resin Choice Matters Most

Your choice of resin is especially important for river tables, thick furniture castings, or any project where single pours exceed a few centimetres in depth. Using the right product helps achieve clarity and smoothness, reducing the chance of cloudiness or set failures.
