Getting your colour just right in epoxy resin projects starts with knowing how much dye or pigment to add. Using the correct ratio ensures brilliant results and reliable curing, whether you aim for subtle translucency or striking opacity.
Recommended Dye Percentages
The standard guidance for adding dye to epoxy resin is to use between 1% and 5% of the resin’s weight. If you prefer a light, see-through tint, aim for the lower end—about 1% pigment. For an intense shade or solid appearance, increase the amount up to but not exceeding 5%. Using more than this can compromise resin curing and clarity, resulting in a tacky finish or loss of vibrant effect.
How to Measure and Mix
Always weigh your resin and calculate the pigment amount accordingly. For example, if you’re working with 100g of resin, add between 1g (for translucent effects) and 5g (for deep, opaque colours). Add the dye gradually, mixing thoroughly until dispersed evenly. Tools like precision scales and mixing sticks are essential for consistent results.
Sets such as the “Renaissance” – Set of Dyes are formulated for controlled use, helping you achieve your desired look with just a few drops per batch.
When This Matters Most
- Jewellery and decorative art: Use precise dye ratios to retain transparency or create custom-tinted marble effects.
- Large pours: Prevent curing issues by never exceeding the recommended 5% dye content.
- Working with different pigments: Check individual dye instructions. Both liquid colourants and powders generally follow the 1–5% rule for safe, consistent outcomes.
