Choosing how to colour epoxy resin is essential for anyone working in resin art, crafts, or DIY projects. Many crafters wonder whether everyday acrylics are suitable or if dedicated epoxy colourants produce better results. This guide explores the compatibility of acrylics with epoxy resin and highlights specialised products designed specifically for vivid, durable, and safe colouring effects.

Overview: Acrylics Versus Resin-Specific Colourants

While acrylic paints are common in general crafting, they are not designed for epoxy resin systems. Adding liquid or tube acrylics to resin may seem convenient, but such products can cause cloudiness, improper curing, or even affect the chemical structure of the resin itself. In contrast, epoxy-specific colourants are carefully formulated to blend smoothly, offer vivid colours, and maintain the resin’s clarity and mechanical properties.

Resin Pro recommends using colourants developed for epoxy systems, as these ensure compatibility and long-lasting, brilliant results. These colourants come in highly pigmented liquid, paste, or powder forms and are intended to create anything from deep, opaque hues to subtle, transparent effects. The best choice depends on your project’s needs—whether that’s making shimmering coasters, dramatic river tables, or intricate jewellery pieces.

Why Use Dedicated Epoxy Colourants?

Resin-specific colourants outperform acrylics by delivering purer colour, smoother mixing, and no unwanted chemical reactions. They are specially engineered to maintain transparency and strength, unlike everyday acrylics, which can create a cloudy or patchy appearance in resin.

“Colourfun Set” – Liquid Epoxy Resin Colourant Set for Solid Colour Effects

They ensure intense, brilliant colours and are easy to mix without causing streaks or affecting the clarity of your work. This set is vegan-friendly and cruelty-free, catering to eco-conscious crafters.

It is easy to blend for subtle shading and does not settle, making it ideal for jewellery, geode coasters, and art pieces where absolute transparency is crucial.

Tips for Colouring Epoxy Resin Safely and Effectively

For optimal results when colouring epoxy resin, always use colourants designed for that purpose, such as those in Resin Pro’s Dyes and Pigments category. Measure pigment amounts carefully—typically 3–5% by weight of the resin mixture, or less for transparent effects. Adding excessive colourant may cause curing problems or cloudiness. If you require special effects like shimmering waves, combining liquid dyes with effect powders delivers versatile creative options. Avoid using acrylics or inks not specifically formulated for epoxy, as they can compromise your project’s strength and appearance. Testing with a small batch before committing to a final pour is always wise for custom applications.

Creative Freedom with the Right Colourants

Using the correct colourants unlocks new project possibilities—from vivid river tables and jewellery with transparent hues, to realistic seascapes and intricate geode designs. Match your colourant choice to your artistic vision to achieve lasting and professional results.
