If your project calls for deep resin pours up to 5cm thick—such as river tables or large castings—using the right epoxy is critical for a clear, durable finish. Here’s what you need to know to succeed with deep pour resin work.
What Makes Deep Pour Epoxy Different?
Epoxy formulated for deep pour applications is designed to control heat build-up and minimise bubbles in layers up to 5cm thick. Products like EpoxyTable 5-Five offer low viscosity and a slow curing process, which help achieve a crystal-clear result even in thicker applications.
- Allows casting in single layers up to 5cm for small-to-medium surfaces
- Reduces exothermic reaction for safer, more reliable results
- Formulated with UV filters for clearer, long-lasting finishes
Layering Techniques for Larger Surfaces
For projects with particularly large surface areas—such as tabletops exceeding 100cm in width—it’s typically advised to pour in multiple layers, even if each layer is within the 5cm limit. Waiting 6–8 hours between layers helps prevent overheating and ensures even curing throughout the depth.
- Prepare surfaces and barriers before starting
- Mix carefully, following the specified resin-to-hardener ratio
- Monitor the curing process and avoid disturbing the resin between layers
When This Matters
Choosing a deep pour epoxy is essential when your design needs transparent, thick layers in one go—such as river tables, encapsulated objects, or complex moulds. Using a standard coating resin for these depths can lead to cracks or yellowing due to excessive heat.
