Here's why: resin is an oil byproduct. Because of this, pigments made from acrylic, water, and even some weirdly blended oil-based pigments don't mix properly. They may even leave an odd coating on the final result or become clumpy.

To achieve your chosen hues, we advise using pigments based on solvents, concentrates, or mica powders.

As long as the powder doesn't make up more than 5% of the final product, powders like mica and glow powders can also be added to our epoxy.

If you decide to experiment outside of what we advise, start small. If necessary, we do offer some color alternatives on our online shop.

If you need some, we also have some in our store.

There are countless options; visit our website to view all of our offerings.
