Resin is resin, right? There are so many resin formulas out there. How are you supposed to know what to use in the battle of resin vs. epoxy?
Let’s start by exploring what resin is
Resin is a unique chemical mixture that has been a part of nature for a very long time. It is a liquid mixture that, under certain conditions, will harden. This happens when you mix resin with hardener (two-part resins) or expose it to ultraviolet light (UV resin). And you may already be familiar with nature’s resin — amber.
So, what’s the difference between resin and epoxy?
Epoxy is a specific type of two-part resin. Epoxy resins are the most commonly used type of resin for crafting and creating art with resin. They’re perfect for resin beginners because they’re the easiest to measure and mix.
So if you had a resin vs epoxy battle, there wouldn’t be a winner because epoxy IS a type of resin.
Huh. So what other types of resin are there?
Polyester resins cure very hard. But you need to know how you’re using it before you mix it. The amount of hardener you add varies on the thickness of the pour. Plus, they’re really stinky.
Both of these resin types are fun to craft with once you’re beyond the making messes and mistakes phase.

How will you know if a resin formula is an epoxy resin?
You should see this information on the resin kit label or product description. You can also review a resin’s safety data sheet. Most importantly, if you aren’t sure, ask. Using the wrong resin means you might make something ugly, sticky, and full of bubbles.
How do I know which epoxy resin is the best one for my project?
When understanding resin vs epoxy (versus any other formula), it’s much like buying paint for your house. There are many epoxy resin formulas to choose from.
But ultimately, here’s what you need to know:
There is no ‘one size fits all epoxy resin’.
You’re looking for the best epoxy resin. But first, you need to visualize the specifics of WHAT you want to create.
Are you trying to coat a surface or fill a mold?
Surface coating resins are also known as doming resins.
They mix thick and self-level. You’ll want this resin type if you want an even, glossy coat of resin over a painting, countertop, tumbler, or another surface. But, their stiff consistency is why you shouldn’t pour doming resins in depths greater than 1/8 inch. It’s difficult for all the bubbles to release before the resin starts curing.
Your other choice is to use epoxy resin for molds which are known as casting resins.
They mix very fluid and release bubbles quickly. You can pour them in depths as deep as two inches, and they cure bubble-free. Casting resins are what you want to use when creating resin river tables, paperweights, and other large resin statuettes. But, they don’t self-level. If you pour them on a flat surface, they’ll leave dimples.
⭐️ BONUS: There are other differences between these formulas too. If you want to know more, read about the differences between casting resins and doming resins.
How much resin do you want to use at one time?
Epoxy resin formulas also differ in how much you can mix at once. Mix up too much, and the resin heats up too quickly. Mix too little, and it may not get warm enough to harden.
How do you mix epoxy resin?
Epoxy resin kits come with specific mixing instructions. They typically mix by volume with a particular amount of Part A (the resin) with a particular amount of Part B (the hardener). Obey the directions and don’t deviate from the ratios. If you do, your resin may not cure.
⭐️ BONUS: If you are new to the resin vs epoxy battle, here’s how you mix resin and hardener in five easy steps.
How long does it take resin to cure?
Curing times are also specific to the resin kit. Some epoxy resins can cure in as few as eight hours, while some may need two to three days. Your resin instructions will detail the resin drying times.
Of course, it’s hard to cover everything you could need to know when buying a resin. Here are the ten questions you should have answers to before you buy a resin.
So now that you know what’s the difference between resin vs epoxy, where can you buy the stuff?
