Thank you for the response! I am working with epoxy resin which I know is not as dangerous. Do you know how long I need to worry about the fumes? I know it can take 3 days for a full cure. Do I need ventilation for the entire 3 days? I was thinking I would maybe crack a window while mixing, then seal up the room for 8-10 hours, then crack the window again to vent. Would the 8-10 hours be long enough for the fumes? I dont know how to tell that the danger has passed or when the temp is less important.I am looking into getting a small oven because I also work with polymer clay but there are just so many options! Too many to pick from.I am very lucky to have my little room! I do have to be careful though to keep the cats out. Sometimes they sneak in and I shut them in there. Dont want to do that during a resin cure!Thanks again!

8 to 10 hours should be fine. I generally only smell anything for the first hour or two. Yes, resin can sometimes take 3 days to cure, but that is generally a hard cure. Once it is at the soft cure or demolding stage, the fumes wont be a problem at all.
Hmm. Cat hair and resin. Yes, thats a nice combo.
(Said no one ever.)

This question comes through email by Kayleigh:
Hello there! I have only recently gotten interested in resin and I love your site! Heres my question. I live in the Midwest and it is now too cold to mix and store my resin outside. Id love to be able to keep doing it through the winter but I am concerned about health. I have a craft room but in order to ventilate I would have to open a window, but then I doubt I could keep the room at 70 degrees! Im not sure what to do. Any suggestions?
- November 11, 2013 at 10:07 am #2069Katherine SwiftGuest
Glad to hear youre taking resin safety seriously! Here a few of my thoughts:
1. Yes, your room needs to be as close to 70 degrees as possible in order for your resin to cure.
2. How lucky you are to have a dedicated craft room! Is there a door to the room? Make sure it seals well when you close it. Add towels to the bottom if necessary.
3. What kind of resin are you working with? If its an epoxy, I would say fume concerns about that are certainly much less than some of the other resins. Working with it in its own room with a door that can close will help. You can always wear a NIOSH respirator recommended for fumes, but generally I find that epoxy fumes are a problem.
4. You can also purchase a toaster oven or create a hot box (cardboard box with a lamp with an incandescent bulb) for curing your resin faster. Most resins will cure faster in a 150 degree oven. Once your resin has cured, you can open the window and let the room air out.
5. If youre working with polyurethanes or polyesters, Im afraid the situation is a little different. Some polyurethanes arent a big deal (check with the manufacturer for safety precautions), but I would never attempt to cast polyester resin in my house. The smell is horrible! You might have to wait until warmer weather to cast them again.

Epoxy resins will give off some kind of an odor. I dont know that its any worse than say, acetone or rubbing alcohol, but you will most likely notice something. If you work with anything other than epoxy, then yes, you do have to worry about what you cant smell (especially with polyurethanes). When in doubt, I would suggest getting a MSDS for the resin you are working with. There will be safety recommendations in that information.
As for your molds, as long as the temperature doesnt go over 150 degrees F, you should be fine. Silicone molds can go higher, but check with the manufacturer to get an exact temperature.

I have returned with additional questions! Still using just epoxy.1. If the ventilation is not good enough, Im gonna know it, right? I wont just drop dead one day?2. Oven curing. Will this melt the molds? I use plastic and silicone.
- November 20, 2013 at 10:30 am #2075kayleighGuest
The MSDS just says "adequate ventilation." Gah! I dont know what is adequate. I suppose I am probably just overthinking this. I am only working with epoxy so there is not a lot to worry about but Im paranoid like that.Thanks for your help!

I guess you answered my question, Im on oxygen can I use resin? Thank You

Speak to your physician about this he/she may be able to give you some guidance. If resin is out of the question, something like Diamond Glaze may give you some fun crafting opportunities.

Has anyone tired a air purifier to remove the smell from your workroom? I am looking to set up a multi craft room (candles, soap and resin)in my garage and would like to keep the cross smells at a minimum.
I can add a small window fan, but I am concerned with Winter that it will get to cold and I’d like to be able to leave the room door open part of the time to the house.
Thank you for your help!

hi there, I have been doing tumblers since September. I am getting a little anxious because my cousin sent me a you tube video of a lady stating she got a blood clot in her lung due to using epoxy. Now I am a paranoid wreck because i have a toddler. I only do the cups when he is sleeping. The room I am using has 2 windows, ceiling fan & air purifier. However the door is like shutter doors (if that makes any sense). When I do the cups I usually have the window cracked, air purifier on and ceiling fan. I also have the shutter doors closed. I also use gloves and a mask. I was using Easy Cast and started using Amazing Cast, but noticed a strong odor. After watching the video I searched up “safe resin/epoxy” and Art Resin came up so I ordered that. What are your thoughts on this? I don’t want to risk my sons health for doing this cups.

I think it’s great that you are taking resin safety seriously. I appreciate that you want to keep yourself healthy for a very long time!
All resins are chemicals and you should use them with the proper safety precautions. I’ve got several articles detailing the safe use of resin here:

When I am doing resin I do it outside because everyone always says you should do it in a well ventilated area. But once I am done I put the molds and resin in my room to cure because if i leave them outside its too cold and they wont cure. Is it safe for me to leave them in my room for them to cure? thank you <3

How far away do you have to be to be safe? How far can the fumes waft?
- October 1, 2020 at 10:50 pm #88869ShannonGuest
You guys, first of all, ventilation isn’t necessary briar if the smell, but bc even epoxy resin lets off fumes that you can’t always smell, but damage body tissue… not to mention, I just read that the stuff falls to the ground(heavier than oxygen I guess), so I’d you have pets, they’re at higher risk. Most epoxy resins note boast that they have low odor, that doesn’t mean there aren’t fumes… these are chemicals. If there’s a rec to wear a mask, bet that until that resin cures, it’s letting off fumes- & someone said once it has soft cured (24 hours), it’s “safe,” there are still chemical reactions going on to continue the cure for another 48 hours- I would think that the risk is less, but I wouldn’t assume complete “safety.” First of all- I’d you’re smart or concerned enough to take precautions for the first 24 hours, what’s the big deal waiting another couple days, just to be sure that you’re not frying your lungs or burning your insides? I have respiratory issues and am trach dependent- I’ve been on a ventilator several times- IT’S NOT WORTH IT!!!! Protect yourself, & if that’s not enough, PROTECTYOUR PETS!!! They are smaller and more sensitive to this stuff- safe over sorry! You can’t smell carbon monoxide, either, but it STILL KILLS!!!!!!

Hi! I am new to resin and want to make sure I know what I need to do as far as safety concerns go. I have not begun working with resin yet, but I have everything ordered. I plan on doing my projects in my laundry room. It’s a pretty nice size and I have a window I can open while I am working. I plan on using a fan as well.
Do I want to close the laundry room door while I am working so fumes don’t go through the rest of the house?
Also my concern is when the items are curing. It’s going to be getting cold and my laundry room is one of the cooler (or warmer) rooms depending on the temperature outside.
I figured I’d have a heater on low to keep the room close to 70 to cure my projects, but the window would be closed for that.
So if I go into the room again to do laundry do I need to worry about the fumes?
Also you have to walk through my 10 year olds room to get to the laundry room so I want to make sure he is safe.
I plan on putting a slide bar lock on the door to keep both my kids out of the room.
I will be using Counter Culture DIY casting resin.
Sorry, this is a lot. I really appreciate the guidance!

Hi I am only using UV resin and I’ve looked up if I need to be taking the same precautions as epoxy resin and haven’t had any luck finding much. The one I use says non toxic and I don’t get off any smells when curing but I’d like to know if you have any advice on which precautions I should be taking. I have a toddler that like to go in my craft room while I’m in there from time to time and I’m kinda worried after my sister telling that I should be taking the same precautions as with epoxy.

I jave a question. The only room i can work in is my bedroom. If I open the window, have a fan pointed at the window, and wear a mask (with N95 filter),would that be safe? Better question, would ot be safe to sleep in that room a few hours later? I will be using UV resin on a small scale for charms and trinkets if that matters.
- January 20, 2021 at 12:22 pm #91666
An N95 mask is not suitable for resin casting. You need a mask that protects you against fumes. I show the one I use in this article: https://www.resinobsession.com/resin-resin-resin/epoxy-resin-safety-precautions/
- February 19, 2021 at 2:39 am #91932SaloniGuest
Can I sleep in the same room as resin since I make it in my bedroom. It is the only room I have.
