- Mixing cups and sticks

Step 1: Prepare Your Work Area and Resin
Begin with a dust-free, level surface and gather all your tools. Wear protective gloves to prevent skin contact with resin and colourant. Measure and mix your epoxy resin according to manufacturer instructions, ensuring it is clear and free of bubbles or debris before any pigment is added. Always start with clear, uncoloured resin before adding pigment.
Step 2: Select the Right Red Colourant for Your Project
Decide if you want a solid opaque look or a transparent red shade. For a high-opacity finish suited to art or casting, consider a dedicated pigment such as “Colourfun” – Liquid Epoxy Resin Colourant. If you prefer subtle, see-through crystal effects, a set like “Magic Crystal” – Set of 5 Transparent Colourants is ideal. Both options blend seamlessly with resin to provide either a bold or translucent result.
Step 3: Mix Your Colourant Slowly and Evenly
Pour your clear, mixed resin into a clean mixing cup. Add the red colourant gradually – a few drops at a time for liquids, or a small amount if using paste. Add colourant in small increments for better control. Stir thoroughly after each addition, making sure the pigment is fully dispersed with no streaks or unmixed pockets. This critical step ensures a smooth red colour throughout the resin.
If aiming for a custom shade, the “Colourfun Set” – Liquid Epoxy Resin Colourant Set allows you to blend red with other tones before mixing into your resin.
Step 4: Adjust Colour Intensity and Avoid Common Pitfalls
Continue adding colourant in measured increments until you’ve reached your desired intensity. For transparent red, stop before the resin develops opacity. Thoroughly mix your colourant to avoid streaks. If you add too much pigment, the resin can lose clarity, not cure correctly, or weaken. Avoid exceeding recommended pigment concentrations. If unsure, consult the product guidance—usually no more than 5% pigment to resin by weight.
Tips and Common Mistakes When Colouring Resin Red
Test a small batch before committing to a full pour to check the shade and depth. Blend thoroughly for consistent results, as unmixed colourant can mar the appearance. Avoid over-colouring; too much pigment can prevent full resin curing or result in a sticky finish. If aiming for special effects or cell patterns in red, consider a specialist additive such as “Resi-Blast” – Cell Effect Additive for Resin Art, 25ml for visual texture.

Yes, different resin-compatible colourants can be combined to achieve custom red shades as long as total pigment levels remain within recommended limits.
How much red pigment should I add to epoxy resin?
Usually, do not exceed 5% pigment by resin weight for full curing and to avoid sticky or soft results.
Will red epoxy resin colourants stain my moulds or tools?
Red pigments may leave a temporary stain on some moulds and tools but can be minimised with immediate cleaning after use.
How do I achieve a transparent red effect in epoxy resin?
Use transparent-specific colourants and add gradually, stopping before the colour becomes opaque.
Why does my red resin look dull or cloudy after curing?
Possible causes include over-pigmentation, incomplete mixing, or using a pigment not designed for clear resin.
Are red epoxy resin pigments suitable for UV resin?
