Deep Pour Resins for Bubble-Free Thick Castings

Deep Pour Resins Enable Thick, Bubble-Free Castings

Deep pour resins open up new creative opportunities by allowing you to create thick, crystal-clear castings without bubbles. These specialised formulations are perfect for statement pieces and large projects.

How Deep Pour Resins Work

Deep pour resins are designed for castings much thicker than standard epoxy resins can handle, often supporting pours from 2cm up to 10cm in one go. Their low exothermic reaction prevents excessive heat build-up, which is crucial for avoiding deformation and cloudiness in your finished project. The low viscosity helps bubbles naturally rise and escape, resulting in clearer castings.

Achieving Bubble-Free Results

To minimise bubbles, always mix resin and hardener slowly and thoroughly. Once poured, most deep pour epoxies will self-degass thanks to their formulation, but working at the right temperature (not too cold) and taking your time is vital. For very large pieces, such as tables with sides over 100cm or more than 5cm thick, it’s best to pour in multiple layers, allowing several hours between each to ensure clarity and stability.

Select a product suitable for your desired pour depth—EpoxyTable 5-Five for up to 5cm, or “Epoxytable 10-Ten” for up to 10cm.
Use reliable formwork sealing (often silicone) to prevent leaks.
Have gloves and pigment on hand for best results and custom designs.

When This Matters: Choosing the Right Resin for Your Project

Deep pour resins are essential for large, striking castings such as river tables, thick countertops, or substantial resin art. For smaller moulds or thinner coatings, a regular casting resin may be a better fit and more economical. Match your resin choice closely to your project’s thickness and scale for the safest, clearest outcome.
