When working with resin, you don’t need to go full-blown hazmat attire, but you do need to exercise a few resin craft safety precautions to make sure you don’t do anything to harm yourself or others.  Here are a few of my basic recommendations when it comes to resin safety:  (On a side note — I see other resin crafters tutorials and videos where basic safety precautions are not taken.  What I’m discussing here is what I do every time I work with resin.)


1.  Have good room ventilation. Make sure there is fresh and/or circulating air in a room when working with resin. Open a window or use a fan if necessary.  This is usually sufficient for many resins, including epoxy.  If you’re working with resin, though, that requires respirator use, you need to do it in an area where fumes can be evacuated or you can leave the room once finished (until the fumes dissipate).

2.  Wear disposable gloves. I prefer nitrile gloves since they are the least likely to react with the resin. (Latex can inhibit curing of some resins.) Other types of gloves may also allow resin through the glove and contact your skin. If you have sensitive skin, consider coating your hands with a barrier cream (available at most pharmacies) before putting on your gloves.  If you’re careful when removing your gloves, you can reuse them, but once they have a tear, you should start using a new pair.  I also suggest being careful when putting the gloves away for future use; if the gloves have resin on them, they will leave resin on where you store them, which will either leave a sticky residue or will adhere to the container.

3.  If you’re working on a large scale project, wear protective clothing. Generally, for small batches of resin, I do not worry about this, but when mixing up large quantities, this is essential for resin craft safety. Also speaking from experience, wear something you do not mind getting resin on. Resin drips will not come out of clothing.

4.  To avoid food contamination, designate items you use for your resin projects as ‘resin only’. Many household items, such as cups, spatulas, silicone baking molds and the like can be great tools for your resin studio.  However, once they are used for resin, they should never be used for food or cosmetic purposes again.

5.  If the resin manufacturer recommends a respirator, wear it!  Some resins, including polyesters and some polyurethanes, can also emit dangerous and noxious fumes.  Note:  Just because you do not smell the fumes when working with these resins does not mean they are not there. When working with resins that require respirator use, wear one approved by the National Institute for Occupational Safety and Health (NIOSH) for fumes and make sure it fits properly. On a personal note, when I work with these resins, I make it the last thing I do for the day, then I leave my studio.  I don’t have a ventilation hood that can draw the fumes outside, so I leave my studio overnight to give the fumes a chance to evacuate.


6.  When sanding, grinding, or drilling resin, wear a particle mask or a NIOSH respirator approved for dust. It is important not to inhale the resin dust, which could potentially cause an allergic reaction.

7.  Wear safety goggles. If you are wearing a dust mask or respirator, you need to be wearing safety glasses as well. They are also necessary if you are working with power tools and resin, such as when drilling, sanding, or polishing.

8.  Clean up spills immediately. Yes, I know this is inconvenient, but you don’t want yourself or some other unsuspecting person to find sticky resin later only to not know what it is.  Acetone works well to clean up spills but wear gloves while cleaning it up. Acetone can draw the resin into your skin and cause irritation.

9.  Clear resin spills on the skin immediately with a good detergent.  If cleaning up a resin spill on the skin, do not use acetone or a chlorinated base product. This will only push the resin deeper into your skin. Use a good detergent (I like Dawn® dish soap) and water.

10.  Dispose of resin products properly. Never pour them down a drain or sewer system. Follow the manufacturer instructions for disposal of unused product and empty containers, which may involve you disposing them at your local hazardous materials collection center.  This article explains more:  How to dispose of resin

11.  Ask for Safety Data Sheets (SDS) for the products you are using. SDS information is the ultimate resource on resin craft safety and will include the chemical composition of the item, safety recommendations, and first aid advice should you have a problem.

Now you may be wondering to yourself, “Isn’t this a little overkill?  I see other resin crafters use the stuff all the time without gloves and such.”  I can’t disagree that if you get some resin on your skin, you don’t need to panic.  Where I hear and read about people having problems is repeated exposure that turns into an allergy.  If this happens to you, stop using resin and consult your physician.  Otherwise, if you follow these safety recommendations, you should be able to enjoy resin for a long time.

Here are more epoxy resin safety precautions you should be taking as well.

  1. Thanks for the safety reminders, Katherine. It’s easy to be tempted to take shortcuts but rarely a good idea, particularly wearing gloves. I’m guilty and I’m sure I’m not alone! And I’ve already ruined a pair of shorts by wiping my bare hands on them without thinking. Anyone else?

  2. I’ve always been afraid to use resin, but recently got a beginners kit online from a jewelry magazine. Since its summer, I’ll set up on the porch and be sure to read all directions. Which products don’t require a respirator and special gloves?

    1. Hi Penny, I would recommend checking the SDS information of the specific product you are working with.

      1. If I cover my resin while curing do I still need to be cautious with fumes? I cure them outside but it’s right beside my bedroom window which couldn’t be fully closed

  3. I just started resin and am wondering what is the best way to clean things like the stir sticks, spatulas etc it? Do it with soap and water while still wet or wait until it’s set and peel it off? I don’t want to have to throw things out after every use… Any suggestions?

  4. Msd sheets on little windows resin seems very safe. Just not sure if I need a respirator. I do wear nitril gloves and apron. Do you see any thing on their MSDS sheets .

  5. Hi there Katherine,

    first of all, thank you for the great posts I receive every so often in my mail box ! They inspire & help a lot.

    I have a question about allergies to cured resin. Have you ever encountered a situation where a person has an allergic reaction to your finished (cured) jewelry? Or maybe some other creater has told you anything about it? I’m asking because I would like to make some resin jewelry for my best friend who has very sensitive skin. Is it a good idea?

    thanks 🙂

    1. Thank you for the kind words. 🙂 Speaking as a non-medical person, I have never heard of anyone having a reaction to properly cured resin. There are lots of things out there made of resin (furniture, dinnerware, etc.) that I would expect that your friend would know by now if she was having a problem. That being said however, I’m sure if you gave it to her with an explanation of what it is, perhaps she could speak to her health care team for advice.

      1. I recently started using Amazing resin clear and my lungs burn while using it. I have been using surgical mask like used for COVID -19. It has only bee 3-4 days I have been using it. Do you know of an odorless brand? I have been opening my kitchen windows and a nearby door but the fumes are awful

  6. Hi, thank you for this list and an otherwise amazing website. I have a question which I’ve tried inding an answer for.

    For how long does epoxy resin create fumes?
    Or is this written on the instructions of resin?
    Thank you in advance.

    1. As long as the resin is in the cure time, I would expect that fumes could be off-gassed. Once it’s done curing, smells may linger (mostly the case with polyester resin).

  7. when I’m working with resin, I always leave the window closed. I realized that the air dust always sticks to the resin pieces while I am working, so I decided to leave the window closed. I open it only when I finish the job and cover the molds with a plastic bowl.

  8. Until when is the resin toxic? How bad is it to sleep in the same room where your resin cures even when the window is open?

    1. Hi! Until resin is completely cured, it is toxic. Please don’t sleep in a room with curing resin, and limit exposure to it while you’re awake. The fumes can cause various lung issues and can lead to permanent damage. It’s best to put your work in a separate room that few people go in that is ventilated well. Hope that helps!

  9. Hey, Thank you for the post. I wonder if I could ask a question? I’ve just started my own small business, which I am loving doing. I’ve also just found out, as in today just found out, that I am pregnant. Can I continue to use resin safely if I continue to wear a mask? Any advice would be greatly recieved. Thank you.

  10. Hi. I want to start working with resin but don’t know if it is safe for me.

    I don’t want to resin really big things, just small things like bezels, keychains and that sort of thing. I think the biggest I wouldwant to go will be a coaster or small trinket holders. Something like that.

    We (my hubby & I) live in a small apartment on a very busy street. If we open a window we get a LOT of noise and a lot of dust.

    That part doesn’t concern me so much. What DOES concern me is that I am on oxygen. I can breathe pretty well for a few hours without my oxygen but will the resin fumes bother me if I wear a mask?

    Also, I would not be able to work or store my projects outside or with the window open because of the dust from the traffic. Will that be a problem with the fumes and curing? Or is there a safe way to store it while it cures.

    What would be the best type of resin for me to use? Epoxy resin, UV resin or stay away from resin all together?

    So many questions, but that’s a start.

    Thank you.

  11. I’ll be in the garage, so is it okay to leave my jewelry curing inside while it’s in its chamber? It’ll be warm inside the garage and people’ll be coming in and out. Also, for contaminated clothing, is it recommended to trash it or thoroughly wash (by hand or washer)? I’m thinking in small spills, not a big one.

  12. Hi, Thank you for posting this I just wanna ask if I don’t use a respirator mask but I have this fan that can convert bad air into fresh air again does that make any different.

    And is it better to do resin outside or inside ?

    Thank you

  13. I’ve been curing resin in a hotel room with the only ventilation being the a/c but it cures in 3-5 hours because I’ve been using a UV light. Do i need a respirator? The instructions only said to use goggles and gloves but i use neither. I’ve only started two days ago and only made a few pendants. Is it okay to continue this until i finish the small bottles of resin i have or should I stop doing this until i have the proper equipment?

    1. Hi Isabella, I don’t use UV resin so I’m not sure what the proper safety precautions are in this case. Does the resin have a safety data sheet that you can refer to?
