Test Your Chosen Pigment with a Small Batch First

← Back to How to colour polyester resin?

Before diving into a large project, testing your chosen pigment in a small batch of polyester resin helps prevent unexpected results and avoids wasted materials. It’s a straightforward step, but one that can seriously improve your finished work.

Why Small Batch Testing Is Essential

Every pigment interacts differently with polyester resin, potentially affecting colour intensity, dispersion, and final finish. By conducting a test with a small amount, you can see exactly how the colour develops once mixed and cured. This allows you to adjust the quantity or try a different pigment if the result isn’t quite what you imagined.

• Confirms pigment compatibility and performance.
• Reduces risk of colour bleeding or uneven finish.
• Prevents wasting large quantities of resin and pigment.

Tips for Testing Pigments Effectively

Start by measuring a small portion of resin following your usual mixing ratio. Add pigment gradually, mixing thoroughly until you reach your desired hue. Pour this trial batch into a small mould or onto a suitable test surface, and allow it to cure fully before judging the result. Remember to note the quantities used, so you can easily scale up if satisfied.

If your interest is to achieve special effects, such as glow-in-the-dark, trying products like Phosphorescent Pigment – Glow-in-the-Dark Additive in a sample batch allows you to gauge visibility and brightness before committing to a larger cast.

When This Matters Most

Testing is especially important when working on decorative pieces or functional items where consistent colour and finish matter. For instance, when incorporating additives such as metallic glitters, like the Metallic Pearl Glitter for Crafts and DIY, or when experimenting with new pigment shades, a small test ensures your creativity isn’t let down by unexpected results.
