"How thick can you pour ArtResin?"
This is one of the top questions we get asked here at ArtResin!
We get it.
Sometimes you might need a thicker layer of ArtResin if you're making
a coaster, or you're embedding objects into your resin, if you're painting in between layers for a multidimensional effect, or heck, maybe you just like the look of a thick layer!
You can do all of that with ArtResin, absolutely, but you need to follow a couple of steps. First though, it's important to keep in mind that ArtResin was designed as a surface coating for artwork, formulated to be poured in thin applications no thicker than 1/8" thick ( 3mm ).
This is for a couple of reasons:
1) ArtResin naturally self-levels to a thickness of 1/8" ( 3mm )
2) If you pour thicker than 1/8", bubbles won't have a chance to escape to the surface to be torched out and you might end up with trapped bubbles in your cured resin.
Now, having said all of this, you certainly CAN get a thick coat, as thick as you like in fact,, but you must pour in multiple 1/8" ( 3mm ) layers.
Here are 2 ways to do it:
1) The 3-5 hr method - this is particularly handy when pouring into a mold
- Pour your first 1/8"/3mm layer
- Torch out bubbles, cover and wait 3-5 hrs until the resin thickens to a gel like state
- Pour on your next 1/8"/3mm layer, torch and cover and repeat these steps as much as you'd like until you reach the thickness you desire.
No need to sand in between layers here ... the tackiness of the uncured resin will provide the tooth necessary for the fresh resin layer to bond to.
2) The 24hr method - this is a great method for artwork around which you've built a dam.
- Pour your first 1/8"/3mm layer.
- Torch out bubbles, cover and wait 24 hrs until your piece is dry to the touch.
- Sand with a coarse sandpaper ( we like 80grit ) to rough up the surface. The idea is to create some tooth for the next ArtResin layer to grab onto.
- Wipe up all sanding residue with a damp paper towel and allow your piece to dry.
- Pour your fresh resin layer.
- Torch out bubbles, cover and wait 24 hrs.
- Repeat as desired until you reach the thickness you'd like.
Keep in mind that ArtResin's recommendation of a full 72hr cure time is based on a 1/8"/3mm layer. The thicker your layers are, the longer the cure time will be. It could take up to a week for a full cure, depending on how thick the final coat is.
So there you have it!
Pour ArtResin in 1/8" layers and have fun creating!!
Great tip! Thank you...
If you do that with petri art in silicone mold similar to what in the video. I mean pour-torch, pour - torch than it is 80% your mold will be ruined, because resin will stick. I am not sure what is the reason behind that, but I prefer bubbles to ruined mold and I can guarantee that only by pouring resin in one layer - wait a little and then torch only one time.
great point, you are right - overtorching will ruin your mold ( and could ruin your resin too! ) but you shouldn't ever torch so much that the mold will get ruined. You only need a very light pass with the torch, lightly kissing the surface of the resin with the torch to get rid of bubbles - you shouldn't need any more than that :)
I wish resin would last me forever 🤣🤣😍😍❤️
And if you use a vacuum chamber?
I would have to measure it but I am pretty sure my little skull mold makes a skull that is taller than that. I just did one pour and it came out crystal clear. Maybe I just got lucky? ;) I still say Art Resin is my favorite. :D - Heidi
That's awesome, Heidi! And yes, sometimes you can get lucky and bubbles aren't an issue, especially if you mix really slowly and your resin and hardener are warm. Since ArtResin was formulated for thin applications, best practice though is to pour in 1/8" layers :)
Hi@@KenshiroBoss - we haven't made our own molds, but a lot of folks use silicone kits that you can buy at the craft store :)
How long do I need to wait inbetween pours? Thanks
You can wait either 3-5 hrs in between pours. Or, if the resin coat has already dried, you'll need to sand down the dried surface before you pour a fresh coat. Here's a blog on the subject:

So I am pouring over glass shards in a wooden frame , trying to make a "floating stained glass window "effect . Bubbles I wouldn't think wouldn't/shouldn't be an issue(if they arise),as there are small spaces between the glass pieces anyways .. I guess I am worried about the integrity of the resin against the glass and up against the wooden frame...Ithere will not be any large swaths of space with just epoxy..at maximum 1/2in thick pour thruout..the inside measurements for the frame are 1 1/2ft² and 1in deep ...I truly wanted to do this in one put but I don't think it's going to happen...😔 any help would be appreciated...like I said,I have never used this brand(for the price I thought it would work) until I got it home, opened the clear plastic carrier it came in to access the information card(because out of the the employees working at Dick blick which I drove an hour to get to by the way I had no idea how to use it or what it was for-@ a whopping 130$ a gallon) the case is open now can't return it I guess I'll figure it out-willing to take suggestions 😔😔😔😔😔😔😔😔😔⭐⭐⭐⭐⭐
Hi Amy, the resin will work well over glass. You will want to be sure all of the air is out from behind the glass pieces so that bubbles don't release as the resin cures. We recommend pouring ArtResin in shallow pours, so you'd be best to pour in layers letting each layer cure for 3-5 hours before adding the next. You can build your depth as much as you want, as long as you pour in layers. You can torch each layer to help clear out any bubbles that arise.
i know you said only 1/8 thick pour to let the bubbles out. im going to make a cast mold 4x4x6 and putting it into a pressure pot to eliminate the bubbles.is 1/8 pour for only bubbles or is there a concern for heat cracks too
Paul,
Great question! Yes it is also possible if pouring too deep for an exothermic reaction to occur. This could cause the resin to heat up, cure very quickly or crack.
ArtResin was designed as a surface coating for your artwork and while many artists due cast with ArtResin the best way to achieve this is in multiple 1/8th inch layers.
I just started by buying the 2 part resin from you, I mixed it 1:1 ratio added my acrylic paints stirred very well, but when I go to pour it’s thick and heavy and not spreadable at all, what am I doing wrong?
Hi Kimberly - sorry to hear that your pour didn't work out! You didn't do anything wrong .... for some reason, there are certain brands of acrylic paint that react with ArtResin - what happens is that they cause the resin to catalyze immediately, which is why you found that it was thick and impossible to spread. There are so many brands of acrylic paint that it would be impossible for us to test them all, so for this reason we always encourage customers to test first, to make sure there is no reaction between the ArtResin and any additives or the substrate, and that your end result is exactly what you were expecting. What you can do is try another brand of acrylic paint, or you can try using our ResinTints which were formulated specifically for compatability with ArtResin. And, no matter what colorant you're using, always make sure you don't add more than 6% of the total combined volume of resin and hardener.
Hope this helps!

Can you advise which brands of acrylic will work?
Hi Kimberly - we use ResinTint here at the studio to tint our resin, but I know I was doing a comparison once between acrylic and resintint and I used either Pebeo Studio Acrylics or Liquitex Basics as that's what we have here at the studio.
You can see the results ( the red circles ) in this blog: www.artresin.com/blogs/artresin/what-can-you-use-to-color-clear-resin
I'm sure there are other brands that work too. But again, always test first to be sure, in case there are differences with pigments, ingredients etc even within the same brand.
Hello, I can't help but feel partially responsible for this.. 😁 I'm sorry, my email is telling me I never responded, but yes this is truly helpful, and I plan on ordering a gallon kit to start here soon. So thank you doubly. (22008) cm005
Thanks - glad you found it helpful!
