How Much Pigment Should I Add to Epoxy Resin?

Ideal Pigment Ratios

The general recommendation is to start with a small percentage, typically below 5% pigment by mass relative to the mixed epoxy resin. For most liquid and paste pigments like the Colourfun Set, only a few drops per 100g of resin are usually sufficient for vivid colours. If you’re aiming for translucent effects, use even less—experiment by adding drop by drop until you reach your preferred shade.

Tips for Mixing Pigment with Epoxy Resin

• Always follow the instructions provided with your chosen pigment for best results.
• Begin with a conservative amount, blending thoroughly before deciding if more pigment is needed.
• Increasing pigment won’t necessarily intensify colour past a certain point; it can sometimes affect resin curing if overdone.
• If working on layered or transparent effects, test a small sample first—the concentrated nature of resin pigments means they tint easily.

When Precision Matters

Measuring pigment becomes crucial for projects requiring consistent colour across multiple batches (such as river tables, coasters, or resin jewellery). Weighing both resin and pigment ensures reproducibility in larger-scale creations or commissioned work.
