← Back to How do you colour epoxy grout?

Not all dyes are suitable for colouring epoxy grout. Selecting the right type of pigment ensures durable, evenly coloured results, as well as a smooth curing process.
Why Specialised Resin Dyes Are Essential
Epoxy grout is a chemical system that requires pigments specifically formulated for epoxy resins. Standard dyes, such as those intended for textiles or water-based products, can interfere with the curing reaction, affect the consistency, and lead to unpredictable colour or weakened grout. Approved epoxy-compatible colourants ensure your grout sets properly and achieves the vibrant shade you expect.
Recommended Colourants for Epoxy Grout
For vivid and reliable colour, use dedicated resin products like Colourfun liquid epoxy resin colourants or concentrated paste sets that blend smoothly into your mixture. These colourants are designed for excellent dispersion and minimal impact on epoxy properties. For customised effects, such as marble patterns or intense coverage, try pigment sets like “Renaissance” for decorative results.
Tips for Safe and Effective Colouring
- Always use resin-specific colourants, and avoid exceeding 5% pigment by weight to prevent issues with curing.
- Add pigment gradually and mix thoroughly for an even tone.
- Test your colour on a small sample batch to ensure satisfaction with the final shade and finish before applying to larger areas.
When This Matters
Choosing the right dye is vital whenever a consistent finish and strong, lasting grout are needed—particularly for decorative surfaces or high-traffic areas that demand durability.
