How to Pour Resin in Multiple Layers for Deep Projects

If you’re considering working on a deep resin project, such as a river table or large casting, pouring your resin in multiple layers is often the best method to ensure optimal results. This approach controls curing heat and helps achieve a flawless finish.

Why Should Resin Be Layered for Deep Pours?

Pouring resin in thick, single layers increases the risk of excessive heat (exothermic reaction) during curing, which may lead to clouding, cracks, or other imperfections. Layering resin allows each stage to cure safely and evenly, supporting greater project depth without sacrificing clarity or bond strength.

Reduces risk of overheating
Improves clarity and quality
Minimises bubbles and defects

Step-by-Step Guide to Layered Resin Pours

Begin by selecting an appropriate deep pour resin, such as EpoxyTable 5-Five for layers up to 5cm, or “Epoxytable 10-Ten” for extra-thick castings. Mix each batch according to the manufacturer’s ratios, and pour one layer at a time up to the recommended thickness (typically up to 5–10cm depending on the product). After each pour, wait for the resin to partially cure—usually 6–8 hours—before adding the next layer. This lets the layers bond effectively and keeps the working temperature in check.

When Layered Pouring Makes Sense

Choosing to pour in multiple layers is especially vital for:

River tables or thick table tops
Large or heavy castings exceeding resin’s per-pour limits
Projects requiring superior optical clarity

Attempting a single, extra-thick resin pour can compromise your project and waste materials, so careful planning and patience are rewarded.
