Can I Mix Two Different Brands of Epoxy Resin?

← Back to How do I mix resins from different suppliers?

If you’re delving into resin craft or repairs, you might be tempted to combine two different epoxy resins to achieve a unique finish or use up leftovers. However, mixing different brands in the same pour isn’t straightforward and can lead to disappointing—or even wasteful—results.

Why Mixing Different Epoxy Resins is Risky

Every epoxy resin formulation is unique. Different brands can vary in mixing ratios, cure times, viscosity, and even the chemical composition of the resin and hardener. When mixed together, these differences often result in incompatibility. Issues can include incomplete curing, tacky or soft surfaces, loss of clarity, or unexpected reactions that can ruin your project.

Each system is designed to work with its own hardener—cross-mixing often disrupts the chemical cure.
Even two clear resins with similar viscosity, like One-2-One and Art Pro, should not be combined in a single batch.
Problems are especially likely if the mixing ratios (by weight or volume) differ.

Safe Practices for Multi-Resin Projects

If your goal is to use different resins in a single piece—for artistic effect or layering—it’s best to pour each layer separately. Allow each layer to fully cure according to the manufacturer’s guidelines before applying the next. For instance, you can pour a cured layer of Art Pro and add a cured layer of One-2-One on top for different effects or properties. This sequential method avoids direct chemical interaction and maintains a durable finish.

When This Matters

Sticking to one resin system per batch is especially important for functional items (like coasters or tabletops) or large pours where curing failures can be costly. Experimentation is best reserved for non-critical, small-scale projects where mistakes are less impactful.
