Should I Pour Large River Tables in a Single Pour?

← Back to Why do river tables sometimes warp?

Wondering whether to pour your large river table all at once or in stages? Approaching large volume pours with care is essential for a stable, professional result and to avoid costly mistakes like warping.

Why Layering is Recommended for Large Pours

For river tables that exceed 100cm on any side or use more than 8kg of epoxy, pouring in multiple layers is the proven approach. Applying all your resin in a single pour can cause excessive heat build-up, which may distort the wood, cause bubbles, and lead to unwanted warping as the project cures. Layering allows each segment to partially set and cool, greatly reducing the risk of these issues.

How to Pour in Multiple Layers

Begin by pouring your first layer, ensuring it is within the recommended thickness for your chosen resin. For products like Epoxytable 10-Ten, single layers up to 10cm are possible, but large projects still benefit from layering to control the exothermic reaction. Wait 6–8 hours between each pour so the resin partially cures but remains receptive to bonding with the next layer. Repeat until your river is fully cast, following the manufacturer’s thickness guidelines for each product used.

Choosing the Right Resin for Deep Pours

Product selection matters when tackling bigger river table projects. Deep pour resins are specifically engineered to handle more substantial application thicknesses with a lower risk of overheating. For example, “Epoxytable 10-Ten” is suited to projects requiring up to 10cm depth per layer, while “EpoxyTable 5-Five” comfortably covers up to 5cm. These resins make it easier to achieve clear, durable finishes while minimising the chance of distortion.

When Layering Is Especially Important

• If your project will use more than 8kg of epoxy or has long/wide pours over 100cm, layer pouring is essential to maintain the stability of both resin and wood.
• Layering is also advised when working in warm environments or with intricate designs that require even curing and heat control.
