Casting Thicknesses Up to 10cm: What You Need to Know

If you are planning to create resin tables, deep art pieces, or other large epoxy castings, the ability to pour up to 10cm thick opens exciting creative possibilities. Choosing the right resin and following precise techniques is key for successful, safe deep casting.

Selecting the Correct Epoxy Resin for Deep Casting

Not all epoxy resins are formulated for thick castings. For projects requiring pours up to 10cm, select an epoxy specifically designed for super-deep casting. For example, Epoxytable 10-Ten is developed to manage the low exothermic reaction necessary to avoid overheating and bubbles, crucial for thick resin layers. For pours up to 5cm, EpoxyTable 5-Five is a dependable choice. Using a resin not intended for deep pours may result in deformation or incomplete curing, so always check the recommended thickness before beginning.

Layering Techniques for Uniform, Safe Results

Even with deep-casting epoxy, sometimes working in layers is advisable—especially for very large projects or pieces exceeding 10cm in any direction. Typically, each layer should be poured and left to cure (usually 20 to 24 hours) before adding the next. This staged approach helps prevent excessive heat build-up, preserves clarity, and ensures strength throughout the piece. Always follow the manufacturer’s instructions regarding recommended wait times and environmental conditions to achieve a professional finish.

Practical Guidance for Deep Resin Casts

Wear gloves and work in a ventilated space.
Mix thoroughly according to the product’s specified ratio.
Pour slowly to minimise entrapped air and use a heat gun if necessary to release surface bubbles.
Monitor ambient temperature—warmer conditions accelerate curing and can increase the risk of overheating in deep casts.
Avoid using deep-casting resin for thin, surface-level coatings—each type is optimised for a specific application.

When This Matters Most

Casting up to 10cm thickness is essential for river tables, statement artwork, and large encapsulation projects. These jobs demand careful material selection and adherence to pouring recommendations, as the wrong resin or rushed technique can result in costly failures.
