Opaque and Translucent Pastes: Colouring Epoxy Resin Projects

← Back to What dyes are needed for epoxy resin?

Choosing between opaque and translucent pastes allows you to unlock a fresh spectrum of creative effects in epoxy resin projects. Each type offers distinct looks and benefits whether you’re aiming for subtle glazes or bold, solid colours.

Understanding Opaque and Translucent Pastes

Opaque pastes deliver full, rich colour and mask the clarity of the underlying resin. These are ideal when you want a bold, consistent finish—perfect for statement art, marbling, or when concealing inclusions. In contrast, translucent pastes let light pass through, allowing for effects like depths of sea water, layering, or stained-glass styles. Both options blend smoothly into epoxy resin, offering vibrant results without streaks when properly mixed.

How to Achieve Your Desired Effect

The intensity and opacity of your resin colour are largely determined by both the type and amount of paste you add. For a glass-like, see-through tint, use a very small quantity of a translucent paste. For maximum coverage with a saturated hue, increase the amount or opt for an opaque type. Always refer to your paste’s usage guidelines—usually, between 1% and 5% of the resin weight is sufficient. Try mixing different “Colourfun” shades for custom results or blending white and black to create greys for more nuanced designs. You can find versatile sets like the Colourfun Set for a wide range of effects.

When Opaque or Translucent Pastes Matter

• Choose opaque pastes when you need full coverage, want to hide embedded objects, or create flat areas of intense colour.
• Pick translucent pastes to give your resin projects a sense of depth, mimic water or glass, or allow light through layered designs.
