Never Exceed 5% Dye by Total Resin Mass

← Back to How much dye can I add to the resin?

Getting vibrant colour in resin projects is exciting, but controlling how much dye you use is key. Exceeding recommended dye amounts can impact your resin’s performance and final result.

Why 5% Is the Maximum Safe Limit

When colouring resin, it is essential not to exceed 5% dye or pigment by the total mass of your resin mixture. Adding more than this can disrupt the resin’s ability to cure correctly, potentially resulting in a soft, tacky, or weakened finish. Proper pigment use ensures your project stays strong, sets properly and looks its best.

How to Measure and Mix Dye

For most resin colourants, you only need a small amount to achieve vivid results. For example, “Colourfun” liquid colourants are highly concentrated, requiring just a few drops per 100g of resin for a translucent effect. Start low—around 1% for subtle or transparent results, and increase gradually up to but not past 5% of the resin’s total mass for bold, opaque colour. Always weigh your resin and pigment for accuracy and mix thoroughly for an even hue.

When Precise Dosage Matters Most

Large Casts and Artworks: Excess pigment in deep pours or paintings may cause curing issues throughout the piece.
Pouring Transparent Layers: High dye amounts can reduce clarity, affecting transparent or layered looks.
Professional projects: For jewellery or furniture, following recommended limits prevents defects that can ruin a finished piece.
