10 Questions You SHOULD Be Asking Before You Buy Resin

what you should know before buying resin
Before you buy resin for your next project, here are the questions you should be asking.

Wait a minute. So I can’t just buy resin and use it?

Of course, you can.

If you don’t mind

❌ making something crappy
❌ risking your safety
❌ going at it alone

But if you want to make something

✅ bubble-free
✅ shiny and gorgeous
✅ that you can’t wait to use, gift, or even sell

Here are ten questions you should ask before you buy resin for your next project.

1. I want to make ______. Will this resin work for this?

Do you know what’s painful? (Besides #5 on this list.) Buying a resin you think will work for your project only to find out after using it that it failed. Any knowledgeable retailer should be able to tell you whether a resin will work for what you want to make.

💡 Pro tip: You should never hear that this resin will work for everything. There is no one size fits all resin.

⭐️ BONUS: Here’s how my best advice on how to choose the best epoxy resin for your project.

2. What is the pot time, cure time, minimum, and maximum mixing amounts for this resin?

Why does this matter? These numbers will let you know:

*Pot time = how much time you have to use the resin before it starts curing.

*Cure time = how long it takes for your resin to solidify.

*Minimum and maximum mixing amounts = Mix an amount between these two numbers to make sure your resin cures.

You want to be sure the resin will fit your project needs. These numbers will also make it easier to compare one resin to another.

⭐️ BONUS: Get all that information in our [FREE] resin buying guide.

3. What is the shelf life of this resin?

Epoxies generally have a shelf life of twelve months. Polyesters are usually half of that. Polyurethanes are even shorter. Buy enough resin to use entirely in half of the expected shelf life.

And once you’ve opened the resin, use it within 30 days. After that, the hardener can yellow.

⭐️ BONUS: Here’s how to figure out how much resin you need.

4. Is there anything I should not do with this resin?

Anyone that tells you there isn’t anything you shouldn’t do with this resin is either clueless or unethical.

Clueless because they don’t know their product. Unethical because they’re more interested in making a sale instead of helping you make something beautiful.

Again–there is no one-size-fits-all resin. A resin for art isn’t going to work as your resin for crafts.

5. Is this resin appropriate for my skill level?

This question applies to you resin beginners. You should start with an epoxy resin. Don’t start with polyurethane or polyester resins. They are more complicated to measure and mix. It’s also trickier to use them before the pot time expires.

6. Do you have a small quantity of resin I can buy first?

You might be in love with this resin, but let’s go on a ‘first date.’ Only buy a small resin kit to start. If it works for what you want, then buy a larger volume to get a better price.

7. Does this resin conform to ASTM D-4236?

Whoa. What does that even mean?

In a nutshell, if a resin has ‘conforms to ASTM D-4236’ on the label, it means it’s safe to use.

And not all resins have this labeling. (Like 90% of the resins on this site don’t.)

Even if you don’t buy resin at Resin Obsession, please don’t buy resin without this labeling.

Your health and safety aren’t worth the risk.

8. Can you provide me with a safety data sheet (SDS) for this resin?

Oh goodness. More technical stuff? Really? All I want to do is make resin crafts.

And I want to help you do that — safely.

Safety data sheets tell you about the chemicals that you’re using. You’ll learn:

*How to protect yourself when using them
*How to dispose of resin
*Who to call in case of a chemical emergency

And I’m going to say this too.

Any company that won’t give you this information either has something to hide or doesn’t have it to give to you. I would never buy resin where I couldn’t get SDS.

9. What would you like me to know about this resin?

Any company that makes resin for artists (as opposed to boat epoxy) should be able to answer this question faster than a teenager texts juicy gossip.

Each resin has its own quirks and nuances that any experienced resin artist can help you with.

10. How do you use this resin?

This is where you can really learn about working with resin. You should be able to get their best tips and tricks on making it shine. If they can’t tell you much, it means they don’t have experience with the epoxy resin. You want to know that you’re going to get awesome technical support should you need it.

So let me be totally honest for a moment.

Okay, I have been through this entire article, and I can’t thank you enough for reading this far.

If you’re ready to buy resin, I would love the opportunity to help with your resin project. I’ve been a resin artist for more than 15 years and work with a great team of people to provide you with resin for artists.

Not floors. Not boats. Not adhesives.

If you’re ready to jump in, you can buy resin supplies.

But, if you aren’t ready to jump in, I get it. You want to make the most of your time and resources. And making something ugly isn’t what you had in mind.

  1. i would like to resin a high top round bar table. what resin will be the most resistant to scratches?

  2. I would like to mold, color add decorations inside and drill my resin for outdoor hanging decorations. I prefer it to be clear. Which resin would be best?

  3. I would like to add a colored resin to a box lid and be able to use a router to round over the edges. Also to trim the edges with a table saw. Can this be done if taking small cuts?

  4. Hello
    I am running a craft camp and want to make resin crystals from molds I purchased. The molds are bigger then I thought ( about 3 inches tall and a 1 inch to 1 and a half inch wide) I have 8 campers, so will need quite a bit of resin to make them. I will also need them to be able to be removed from the molds and taken home with in 2 hours. I first purchased UV resin that would have worked great but wasn’t able to find it in large enough volumes.

  5. i want to do resin art work.like making tables with clear epoxy resin…i dont know how to mix them.i dont know anything about using resin….please help.i want to learn about resin and do art work..

  6. I am using the resin for making tumblers. I have seen people use alcohol ink on the tumblers which look really good but how safe is it. Does something like alcohol ink break down the resin and make it unsafe?

  7. I’ve used nothing but tr resin. Love it. But. Forearms broke out w red blotches they fade after awhile. Now put castor oil on then Hubbys tube sock up to elbow. Respirator n goggles. What can be done better. Does all resin do this. Turned shed into studio w 3 windows now. Thk u. So glad I learned about resin

    1. Unfortunately, it sounds like you are having a reaction to the resin. I’m not a medical professional and would direct you next to your healthcare provider for advice.

  8. I’m in the very early stages of making a decorative wood surfboard for my wife this upcoming Christmas. I’d like to use coloured resin to fill in the etched out design on the board. Wondering what types of resin work well with wood and can handle sanding, buffing and coming into contact with wood stain? I’m a beginner with resin as well.

  9. I am making tile coasters that have a poured paint design. I have used some resins for jewelry making. Some of it got a bit soft (sticky) in was in a heated area. What type of resin would be best to seal the coasters with a gloss (just poured look ). They might have a wine glass or coffee mug on it. Thank you

    1. Hi Bonnie, are you looking to coat the coasters or use them in a mold. I want to be sure I recommend the right resin.

  10. I want to pour molds to make crystal clear gems, maybe with some iridescence/rainbow to them to hang indoors. I want something that is reminiscent of Swaroski crystals, but affordable! Do you have a brand you recommend for making these in small batches? And what is the best way to introduce iridescent shimmer without obvious inclusions? I don’t want it to look like glitter. Thank you!

    1. Hello. I’ve been making resin crafts for 4 months now. I’ve tried 4 different brands so far. And all of them became bendy last week regardless of how long it had been since I’ve made them. I’ve searched the internet and your blog came up so I wanted to ask for your opinion. The thin bookmarks, thick keychains, coasters… Some were made 3 months ago, some were made last month. But almost all of them became resilient last week. The only thing that comes to my mind is that the weather is especially hot lately but I’ve been told that weather changes don’t affect resin once it’s cured. Is it true or does it in fact affect the resin work? If it does, what temperature should I keep my cured resin crafts?

  11. Hi, your expert advice is required please. We have wood framed doubled glazed windows that are leaking because rain runs down the glass into the frame and is forced out through the beading on the inside in high winds. In the past we have tried putty, it dries out and the birds peck at it, we tried sealants, they shrink and degrade as the wood shrinks and expands in the seasons. Can you suggest a resin that will fill the gaps but is liquid enough to be syringed between the wood and glass?
    Thanks
    Marguerite

    1. Hi Marguerite, I’m afraid resin isn’t a good choice for a project like this. Resin and glass expand at different rates from each other. At some point, one of them will crack.
