Options for Casting in Thick Layers with Epoxy Resin

← Back to How to cast your dream table with epoxy resin

Thick-layer casting with epoxy resin opens up creative potential for river tables, art blocks, and furniture. To get flawless, durable results, you need both the right pouring depth and careful control of curing for every project.

Minimum and Maximum Pouring Thickness with EpoxyTable 5-Five

EpoxyTable 5-Five is specifically designed for deep pours between 2cm and 5cm in a single layer. For best clarity and cured strength, always stay within this range—thinner than 2cm may lead to slow or incomplete curing, while exceeding 5cm in one pour risks overheating and defects.

Minimum recommended layer: 2cm
Maximum per pour: 5cm
For pours above 5cm: Build thickness by layering as detailed below

Safe Layering and Curing for Thick Projects

Projects needing more than 5cm thickness—such as large table centrepieces or art castings—require pouring in multiple stages. Allow each layer to cure until it feels firm but still slightly tacky (usually after 6–8 hours) before adding the next. This method manages heat build-up and ensures each layer bonds strongly, avoiding cloudiness and cracks.

Never force curing with extra heat
Monitor ambient temperature for steady results
For especially large or heavy pours (over 8kg), strict layering is crucial to prevent overheating

Avoiding Overheating and Curing Issues

Overheating is a top concern with thick epoxy resin projects. Too much resin in one pour, or attempting to cure with heat sources, may lead to cloudiness, cracking, or even resin failure. Stick to the specified single layer thickness, and let each layer cure naturally before the next pour.

Do not exceed 5cm in a single layer when using EpoxyTable 5-Five
Allow adequate curing time between layers
Ensure embedded objects are dry and sealed to avoid trapped air

Choosing the Right Resin for Your Pour

Match your resin choice to your project’s required thickness. EpoxyTable 5-Five is perfect for deep, clear pours of 2–5cm. For ultra-deep projects up to 10cm, use Epoxytable 10-Ten. For delicate or decorative work up to 2cm, the Trasparente resin is an option.
