← Back to How many sessions are needed for waxing with resin?


When it comes to projects like river tables and large decorative castings, using an epoxy resin specifically formulated for high-thickness casting up to 10 cm ensures clarity, reduced overheating, and structural integrity. This guide covers what you should know to achieve excellent results with thick pours.
Choosing the Right Resin for Deep Pouring
Not all epoxy resins are created equal for large-volume castings. For depths up to 10 cm, select a product with low exothermic reaction, strong UV-filtering, and long working time. These features help maintain transparency and minimise risks of yellowing or cracking. The “Epoxytable 10-Ten” product page details a resin suitable for such demanding tasks.


Applying in Layers for Safety and Quality
For thick or large castings, it’s best to pour in two or more layers, particularly if working with sides over 100 cm or using more than 8 kg of resin. Leave 6 to 8 hours between layers to prevent excessive heat build-up, ensuring the process remains safe and the final result is bubble-free and clear. Always follow the manufacturer’s instructions for waiting times.
Practical Advice for Large Resin Projects
- Use precise measuring and mixing tools to guarantee the correct resin-to-hardener ratio.
- De-gas mixtures sufficiently to minimise bubbles, especially important in deep pours.
- Maintain a clean, temperature-controlled workspace for optimal curing.

When This Matters Most
High-thickness resin casting is essential when working on art installations, river tables, or embedding objects in large decorative pieces. Using a resin designed for this purpose helps you achieve durability and clarity in complex, multi-stage projects.
