How to Colour or Pigment Indoor Resin Safely

Q: Choosing the Right Pigments for Your Resin Type

For UV resin, such as UV–Creation , dry pigments and glitters work best. These can be mixed directly into the resin prior to curing, providing a vibrant and even colour. Alcohol inks, however, are not recommended for UV resins. If you're using a mineral or water-based resin like NatuResin, wait until the resin has cured, then apply paint or surface-safe pigments for custom decoration. For conventional clear epoxies, both dry pigments and liquid pigments formulated for resin are suitable and can be added before pouring.

How to Pigment or Colour Your Indoor Resin

Adding colour or decorative effects to your indoor resin projects is a creative way to personalise and enhance your finished pieces. The options you choose depend on the type of resin you’re using and the look you want to achieve.

Choosing the Right Pigments for Your Resin Type

For UV resin, such as UV–Creation, dry pigments and glitters work best. These can be mixed directly into the resin prior to curing, providing a vibrant and even colour. Alcohol inks, however, are not recommended for UV resins. If you’re using a mineral or water-based resin like NatuResin, wait until the resin has cured, then apply paint or surface-safe pigments for custom decoration. For conventional clear epoxies, both dry pigments and liquid pigments formulated for resin are suitable and can be added before pouring.

Techniques for Mixing and Application

To achieve a consistent tint, start by adding a very small amount of pigment, blending thoroughly until you reach your preferred hue. Stir slowly to minimise air bubbles, especially in UV and epoxy resins. For mineral resins and kits like the Coasters Creative Kit, use the included pigments to experiment with marbling, layering, or blending effects. Once fully cured, both mineral and epoxy resins can be further enhanced with acrylic paints or metallic highlights for additional flair.

When This Matters

Choosing appropriate colouring methods is crucial for artists pursuing unique finishes, jewellery makers matching specific palettes, or hobbyists keen on achieving a professional outcome. Using the right type and quantity of pigment prevents curing issues, maintains transparency when desired, and ensures your project will last.
