How do I prevent my coloured resin from going cloudy?

Nothing is more frustrating than seeing your resin project turn cloudy when you wanted clear, vivid colour. With the right approach, you can achieve a stunning transparent effect every time.

Choose Compatible Pigments for Clarity

Your choice of pigment plays a huge role in the clarity of your coloured resin. Always select pigments specifically formulated for use with two-component resin systems, such as Colourfun liquid colourants or the Colourfun Set paste range. Transparent dyes like Magic Crystal maintain the resin’s glass-like effect. Avoid general craft or water-based pigments, as these may not disperse evenly, leading to cloudiness or streaks.

Mix Thoroughly and Avoid Oversaturating

Cloudiness is often caused by trapped micro-bubbles or insufficient blending. Stir your resin and hardener first until streak-free, then add pigment gradually, mixing carefully to achieve an even dispersion. Too much pigment—usually more than 5% by weight—can reduce transparency or lead to uneven curing, so use just enough to reach your desired shade.

When This Matters: Projects Needing a Crystal Finish

If you’re working on projects like jewellery, river tables, or artwork where light should pass through with clarity, following these tips is essential. Clouding is especially noticeable in clear and vibrant colour effects, making careful pigment selection and mixing crucial.
