How Much Colourant Should I Add to Epoxy Glue?

If you’re looking to achieve bespoke colours in your epoxy glue projects, getting the right balance of colourant is crucial. Too little may look washed out, while too much risks affecting the performance of your resin.

How Much Colourant is Best?

The general guidance is to use up to 5% of colourant by resin weight when adding pigment or dye to epoxy glue. This ensures vibrant colour while keeping the integrity of your mixture. Adding more than this can affect curing and lead to loss of clarity or weakened results.

Start by mixing your resin first, then gradually add colourant a drop at a time. Stir well and check the colour depth—often, highly concentrated options like the Colourfun Liquid Epoxy Resin Colourant will provide noticeable results with just a few drops.

Practical Application Tips

Measure your resin and calculate 5% of its weight for your maximum colourant amount.
Always add pigment gradually, mixing thoroughly after each addition to avoid streaks.
For transparent tints, choose a specifically formulated product such as “Magic Crystal” – Transparent Resin Colour for vibrant, glass-like finishes.
Paste sets like the Colourfun Set are ideal for creating strong opaque or special effects with ease.

When this Matters Most

Getting the right amount of colourant is especially important for artistic projects, jewellery, or thick castings. Exceeding the recommended amount may compromise both appearance and long-term durability—so measure carefully for best results.
