Crafting with resin seemed like a good idea at the time. Make a resin bowl or keepsake pendants. Or compose a piece of epoxy art for your living room. But now you find yourself calling the resin obscenities like ‘YOU zit-popping puff poodle!’ and you’re wondering where you went wrong. While creating with resin is fun, it can be a fussy beast as well. 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 stains or dark areas like it’s wet. This happens when the resin soaks into the item.
These items need sealing before including them in resin.
Problem #2: Resin castings are full of tiny bubbles.
Here’s the BEST and EASIEST way to avoid bubbles in resin.
Be sure you’re choosing the right resin for what you want to make.

Problem #3: Resin is sticky after the curing time.
This can be anything from sticky on top to a big goopy mess.
The number one reason your resin has sticky spots is that it was undermixed. (This is the #1 resin beginner mistake.)
But, if your resin is goopy, it didn’t get hot enough to cure. There are a few reasons for that. Here’s what you need to check for 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. You must mix the minimum amount of resin needed for the curing chemical reaction.
Wondering if you can fix that gloopy resin?
If your pieces are tacky only on top, you can recoat them with resin. 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.

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 the cured resin is stuck to a plastic mold, you can try placing the mold in the 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, I’m afraid there’s no way to get that out without tearing the mold. You can remove the resin and sand away the silicone, but that mold is toast.

Problem #5: Resin cures too quickly.
Feeling heat is part of what is normal about resin. But excess heat causes the resin to cure very quickly.
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.
