Can You Use Water-Based Colours in Mineral Resin?

Q: How to Add Water-Based Colours to Mineral Resin

During Mixing: Add a measured quantity of liquid water-based pigment or dye to your prepared resin and water blend before pouring. Mix thoroughly to ensure the colour disperses evenly. Post-Curing Decoration: Once your mineral resin object has cured and hardened, use water-based paints or inks to add designs, highlights, or finishes. Mineral resin’s matte, absorbent surface makes it ideal for post-cure painting. Start with a small amount of colour and build up until you achieve your desired effect. Always follow product-specific instructions to avoid affecting the resin’s integrity.

Using Water-Based Colours with Mineral Resin

If you’re interested in customising mineral resin with colour, water-based options are a practical and safe choice. Read on to discover the best ways to use them in your creative casting and craft projects.

Why Water-Based Colours and Mineral Resin Pair Well

Unlike traditional epoxy resins, mineral resins—such as those found in the NatuResin system—are designed to be mixed with water. This unique property makes them naturally compatible with water-based colourants. When added during the mixing stage, water-based dyes and pigments integrate smoothly, helping you achieve an even and reliable colouration throughout your piece. You can also apply water-based acrylic paints or washes to mineral resin after it’s fully cured for extra detail or decorative effects.

When This Matters

Choosing water-based colours is especially important if you prioritise safety, eco-friendliness, and ease of clean-up. Mineral resins are a favourite in crafts for use with children, home studios, or when working in spaces sensitive to solvents and fumes.
