How Much Colourant Should I Add to Epoxy Putty?

Getting the right amount of dye in your epoxy putty is essential for vivid, reliable results. Too little colourant might disappoint, but too much risks poor curing and a sticky finish. This guide explains how much dye to use and tips for consistent colour.

Recommended Dye Percentage

For best results, keep your colourant within 1–5% of your putty’s total mass. This range gives you flexibility, so you can achieve either soft translucent shades or bold opaque colours. Exceeding 5% is not advised, as it may interfere with the curing process and final strength of your epoxy putty.

Tips for Mixing and Measuring

Always measure dye by weight, not by eye, for consistent shades each time. Start on the lower end—especially with highly concentrated options like Colourfun liquid colourants, where a little goes a long way. Gradually blend dye into fully mixed putty, stirring thoroughly to ensure the pigment is evenly distributed throughout and streak-free.

Use digital scales for accuracy.
Add small amounts and mix fully before deciding if you need more.
Keep notes for batch replication if needed.

When This Matters Most

Staying within recommended limits is especially important for detailed or structural projects. Overdosing dye can cause incomplete curing, leaving your putty soft or sticky. It’s also key when aiming for precise colour matching in creative work, such as resin art, repairs, or decorative finishes.
