Can I Dispose of Resin Mixed With Pigments the Same Way?

Safe Disposal of Pigmented Epoxy Resin

Pigments added to your epoxy do not change the core method of disposal. The crucial step is to let all mixed resin, whether coloured or clear, fully cure before discarding it. Once the resin and hardener have reacted and set completely, the material becomes inert and stable.

After curing, small amounts can generally go into your household waste. However, uncured or partly mixed resin—even with pigments—should never be poured down the sink or discarded with general rubbish. Always wear gloves and keep your workspace ventilated during use and curing.

Practical Curing and Disposal Tips

• Combine leftover part-mixed resin and pigments, allow the mixture to fully harden in a safe container.
• Check that the resin is no longer tacky and has cooled before handling for disposal.
• Avoid creating large, thick blocks which can overheat as they set—smaller batches are safer and cure more evenly.
• For larger projects using products like EpoxyTable 5-Five, pour leftovers into shallow, disposable trays to speed up curing and prevent overheating.

When This Matters

This guidance is particularly important for anyone casting with deeply pigmented decorative resins, or frequently working on creative projects where leftover mixtures are common. Proper disposal ensures safe handling and compliance with local waste regulations.
