What to Do If Resin Turns Cloudy?

← Back to How to colour resin with acrylics?

Resin projects are at their best when crystal clear and glossy, but sometimes your resin may turn cloudy—especially after colouring. Fortunately, there are practical ways to bring back transparency and prevent cloudiness in future pours.

Why Does Resin Become Cloudy?

Cloudiness in resin is typically caused by excessive pigment, incompatible colourants, or tiny air bubbles trapped during mixing. When using colourants, especially when colouring transparent resin, it’s important to choose products designed for resin to support a clear result. Using too much pigment can disrupt the resin’s chemical balance, leading to a hazy or milky finish.

How to Restore Clarity

• Use Less Pigment: Always start with a small amount—just a drop or two at a time—and gradually increase if you want a deeper shade. This minimises the risk of cloudiness.
• Pick Compatible Colourants: Choose colourants formulated for resin, such as the Colourfun Set, to ensure good dispersion and clarity.
• Mix Thoroughly but Gently: Stir slowly to avoid trapping air, and let the resin sit for a few minutes to allow bubbles to rise before pouring.

When This Matters

Restoring or maintaining resin clarity is crucial for jewellery, decorative pieces, or any projects where a glass-like appearance is desired. These tips help ensure your coloured resin pieces remain vibrant and professional-looking.
