An epoxy mix ratio calculator simplifies this process by ensuring precise measurements, leading to optimal performance and durability of epoxy projects.

How to Use

  1. Input Values: Enter the required parameters such as the volume or weight of resin and hardener into the respective fields.
  2. Click Calculate: Press the “Calculate” button to compute the appropriate mix ratio.
  3. View Results: The calculated mix ratio will be displayed, ensuring accurate proportions for your epoxy mixture.


The formula for calculating the epoxy mix ratio is:

Example Solve

Let’s consider an example where we have 32 ounces of epoxy resin and 8 ounces of epoxy hardener.

So, for every 4 parts of epoxy resin, we need 1 part of epoxy hardener.


Q: Why is it important to use the correct epoxy mix ratio?

A: Using the correct mix ratio ensures proper curing and bonding properties, leading to the desired strength and durability of the epoxy.

Q: Can I mix epoxy resin and hardener in any ratio?

A: No, deviating from the recommended mix ratio can result in incomplete curing, tackiness, or brittleness in the epoxy.

Q: How do I measure epoxy resin and hardener accurately?

A: Use precise measuring tools such as graduated cups or digital scales to ensure accurate measurements.

Q: What should I do if I accidentally mix the wrong ratio?

A: It’s best to discard the mixture and start over with the correct ratio to avoid compromised performance of the epoxy.


An epoxy mix ratio calculator simplifies the process of achieving the perfect blend of resin and hardener, ensuring optimal performance and longevity of epoxy projects. By following the correct mix ratio, you can achieve professional-grade results in various epoxy applications.
