Measuring our art resin epoxy can be a tricky thing. We get asked all the time "how much epoxy do I need?" And that changes depending on each and every project.

Knowing the amount of product required is crucial before starting your project. Once Part A and Part B are combined, the curing process begins and you have a limited amount of working time before the epoxy hardens.

But don’t worry, we’ve put together an epoxy calculator that will help you understand exactly what you need, for whatever project you’re working on.

Tips and tricks to save some epoxy:

It’s always better to err on the side of having 20% more epoxy than your project needs. That doesn’t mean you have to use it all. We’ve put together a few tips to help you control your epoxy use, now that you know exactly how much epoxy you need from the epoxy calculator.

  1. Use a mold for your project: When working with a project like a river table, it is crucial that you seal all of your edges so that no epoxy goes to waste. 
  2. Wait to pour until you’re ready: Make sure that you have confirmed your measurements and used the epoxy calculator before you pour. This will ensure you don’t spend your working time with the epoxy measuring, you’ll be able to go right into your pour.
  3. Scrape the sides of your cup when mixing: The last thing you want is to ruin a whole batch of epoxy. Scrape the sides of your cup while mixing to ensure that you don’t waste epoxy, and that you get the exact amount the epoxy calculator directed.
