You can now purchase a single bottle of Hardener (in the size you need) without having to buy a full kit.

We get it — sometimes things don’t go as planned. A spill, a mix-up, or an uneven pour can happen. Whatever the case, we’ve got you covered!

Please note: We don’t recommend mixing different brands of resin and hardener. Epoxy formulas vary, and each brand’s components are specifically designed to work together. Always pair ArtResin Resin with ArtResin Hardener.

Why is the hardener sold separately from the resin?

Sometimes, things don't go as planned. A spill, an uneven pour, or an accidental mix-up between bottles can leave you with leftever hardener but not enough resin.

Purchasing a single bottle of hardener lets you replace just what you need without buying a full kit. It's a convenient, cost-effective way to stay stocked up and ready for your next project.

Can I use ArtResin's hardener with any brand of resin?

No, we don't recommend mixing different brands of resin and hardener. Each brand has its own unique chemical formula and the products are designed to work with each other. Mixing ArtResin's hardener with a resin from a different brand can not be considered food-safe and may even lead to problems curing.

Is this hardener compatible only with ArtResin epoxy resin?

Yes - ArtResin Hardener is specifically formulated to work only with ArtResin Resin. Together they create the perfect chemical balance for a clear, strong, and long-lasting finish.

How do I know if my existing resin is safe to use with this hardener?

If your resin is ArtResin, it's compatible! It doesn't matter if the package sizing is different, as long as it's the ArtResin brand.

However, if your existing resin is from another brand, don't risk it - mixing brands can prevent proper curing and could potentially ruin your project. Always use ArtResin's Resin and Hardener together for the best results.

What happens if I mix ArtResin's hardener with an incompatible resin?

Mixing different resin and hardener brands can cause serious curing problems — such as sticky, soft, or uneven surfaces that never fully harden. To ensure the best results, always pair ArtResin Hardener with ArtResin Epoxy Resin only.

    Resin was easy to mix and pour over my 30"x30" mixed media acrylic painting on canvas. Resin is perfectly clear and look amazing

    Art Resin makes crystal clear resin letters

    I used the Art Resin to make alphabet letters for my nieces. They came out great. I did pour in layers every 2 hours and there were no pour lines. I included fairy lights and it worked out beautifully.

    Exactly what I needed

    I had the tail end of my hardener get cloudy so I didn’t want to use it. This is perfect to replace that part of it. Thank you for making these available.
