You’re excited about making a resin bowl or mandala pendants. Or maybe you’ve got aspirations of making a piece of epoxy art for your living room. What you didn’t count on was calling your resin obscenities like ‘YOU zit-popping puff poodle!’ because things didn’t turn out like the picture in your head. While creating with resin is fun (promise!), it isn’t without a few mistakes and obscenities along the way. Here are the five most common resin troubleshooting problems you’ll run into and what you can do about them.
Problem #1: Stains or dark areas on embedded items.
You add papers or porous items into your resin, only to see later that they have stains or dark areas like they’re wet. This happens when the resin soaks into your item.
Anything that looks different when it’s wet needs sealing before including it in resin.
Problem #2: Cured resin is full of tiny bubbles.
The BEST and EASIEST way to avoid bubbles in resin is to choose the right resin for what you want to make.
And how do you do that?

Problem #3: Resin cured with sticky spot or not at all.
You use your resin only to find later that you’ve got sticky spots. Or maybe worse — it’s a gooey mess.
The number one reason your resin has sticky spots is that it was undermixed.
This is also the most common resin beginner mistake.
But, if your resin is like saltwater taffy, it didn’t get hot enough to cure.
(and you shouldn’t eat either 🦷)
Here’s what you need to check for in this resin troubleshooting dilemma:
1. Follow label directions precisely.
2. Measure accurately. Use resin mixing cups to measure and mix your resin.
3. Make sure your mixing utensils and containers are dry. Resin hates water.
4. Ensure you’re mixing the minimum amount of resin needed for the curing chemical reaction.
Unfortunately, if your resin is a semi-congealed mess, there isn’t an easy way to save that resin. You can try removing it, but it might have you throwing around the Zit-Popping Puff Poodle insult again.
But, there’s hope for your sticky stuff.

Problem #4: Resin sticks to your mold.
This is why I always recommend using a mold release — even with silicone molds. Mold release may be the only way you demold your resin in situations like this.
If your cured resin is stuck to a plastic mold, you put the mold in your freezer for 10 to 15 minutes. Then, remove the mold and smack it on a hard countertop. Hopefully, the resin will pop out. Unless it’s a plastic mold that wasn’t meant for resin. If you used something like a soap mold with resin, that thing’s a goner.
If the cured resin is stuck to your silicone mold, the freezer trick might work. But it might not.

Problem #5: Resin cures too quickly.
Feeling heat is part of what is normal about resin. But excess heat causes the resin to overheat.
The most common reason this happens is that you mixed too much resin. Resins have a maximum mixing amount. Go above this, and your resin flash cures.
How are you supposed to know what’s the maximum mixing amount for a resin?
