Deep Pour Application

If you’re eager to learn more about the process from the concept phase through to a flawless finish, explore our deep pour resin projects overview for tips, inspiration and step-by-step guidance on creating your own river tables and showpieces.

Deep pour application is essential for anyone looking to create large, visually striking epoxy resin projects—from river tables to dramatic castings or art installations. If you need to pour resin layers ranging from 2 cm up to an impressive 10 cm in a single session, understanding deep pour techniques, materials, and troubleshooting will help you achieve the ultra-clear, bubble-free finishes that make these pieces truly standout.

To achieve glass-like results in river tables and encapsulations, mastering deep pour casting is crucial. The deep pour casting process involves precise resin selection, careful control of ambient conditions, and thorough preparation to prevent common pitfalls such as exotherm, cloudiness, or trapped bubbles. By applying professional techniques throughout each stage, you ensure durable, flawless outcomes for your tables and art pieces.

Depending on the artistic effect and thickness you want to achieve, there are various deep pour applications suitable for river tables, encapsulated artwork, and statement furniture. Selecting the right resin and pour method helps you realise your vision—whether that’s embedding natural materials or casting large single layers for seamless clarity.

What is Deep Pour Application?

Deep pour refers to casting an epoxy resin layer thicker than 2 cm in a single application. For most river tables, countertop features, or statement art, pours of 5-10 cm are common, demanding resins specifically formulated for such depths. Attempting this with normal or floor resins often leads to excessive heat (exotherm), bubbles, and yellowing.

Why Standard Epoxy Isn’t Enough

Conventional epoxy resins are intended for thin coatings. Using them for deep pours can cause overheating and incomplete cures. Deep pour epoxies, on the other hand:

• Are engineered for thick layers (up to 10 cm)
• Feature very low exothermic reaction to prevent cracks and heat damage
• Have slower cure times, allowing trapped air to escape for a bubble-free finish
• Include UV filters to keep your casting crystal clear for years

Best Practices for Deep Pour Application

1. Choose the Right Resin System

Select a specialised deep pour epoxy. Epoxytable 10-Ten is designed for massive castings up to 10 cm thick, while EpoxyTable 5-Five is ideal up to 5 cm.

2. Prepare Your Workspace & Materials

• Formwork: Use secure, well-sealed moulds to contain the liquid resin. Cut and seal all joints to prevent leaks.
• Temperature: Work between 20–25°C in a dust-free, dry environment. Colder settings can slow curing, while excess heat accelerates exotherm risk.
• Moisture Content: Make sure wood or inclusions are well dried and sealed to avoid cloudiness or bubbling.

3. Mixing & Pouring Deep Epoxy Layers

• Carefully follow mixing ratios (often 4:1 by volume or as instructed).
• Mix gently but thoroughly—vigorous stirring introduces air bubbles.
• Pour in a slow, steady stream into the centre, letting resin flow outwards.
• For very thick applications, pour in stages if your project’s depth approaches the maximum capacity per layer.

4. Managing Exotherm and Bubbles

• Bubble release: Torch, heat gun, or leave resin to sit as bubbles escape on their own due to low viscosity.
• Heat management: Do not exceed maximum recommended pour thickness per manufacturer guidelines to avoid overheating.

5. Curing and Demoulding

• Allow slow, ambient curing. Avoid moving or disturbing the piece during this period.
• Deep pours can take up to 72 hours or more to fully cure. Only de-mould once fully hardened and cool.

Troubleshooting Common Deep Pour Issues

• Cloudiness: Result of moisture or unsealed porous materials—ensure all elements are dry and sealed before pouring.
• Bubbles: Slow pouring and low viscosity resin vastly reduce trapped air; a heat gun can help remove surface bubbles.
• Overheating: Reduce pour thickness or ambient temperature to control the exothermic reaction.

Product Recommendations

• Epoxytable 10-Ten – Deep pour epoxy for up to 10cm, with superior clarity, bubble resistance, and UV protection.
• EpoxyTable 5-Five – Excellent for single pours up to 5cm, maintaining scratch resistance and stability.
• River-Table Complete Kit – All-in-one kit including deep pour resin (up to 5cm), pigments, and tools—ideal for first-time creators.

Final Tips

• Always check the recommended maximum pour depth for your resin product.
• Test on a small sample if unsure about wood compatibility or pour behaviour.
• For large or especially thick tables, pour in multiple staged layers if you’re near the maximum recommended thickness.

With the right planning and resin system, your deep pour application can yield clear, spectacular, and durable results—making your table or artwork the highlight of any space.
