Deep pour epoxy resin is specially engineered for projects requiring thicker casting, such as river tables, large art pieces, and decorative objects. Choosing the right product and method is crucial for clear, strong, and bubble-free results.
What Makes an Epoxy Resin ‘Deep Pour’?
Unlike standard resins, deep pour epoxies are formulated to be used in layers far thicker than 1-2cm—often up to 5cm or even 10cm at a time. The key difference is their low exothermic reaction, which helps prevent cracking or yellowing during larger pours. For example, EpoxyTable 5-Five is designed for safe, clear pours up to 5cm in one go, making it ideal for large casting projects and river tables.
Practical Tips for Deep Pour Projects
- Pouring in Layers: For extra-thick applications above the product’s single-pour maximum (e.g., over 5cm or 10cm), work in several layers, allowing partial curing between pours.
- Mixing and Bubble Control: Ensure careful mixing and avoid whipping air in. Low-viscosity deep pour formulas help bubbles rise and escape during curing.
- Temperature: Pour within the recommended temperature range for best results and to minimise the risk of overheating.
When This Matters Most
Deep pour epoxy is essential when working on thick resin river tables, embedded objects, lamp bases, or large decorative blocks. Attempting these with ordinary resin risks trapped bubbles, yellowing, and even thermal cracking.
