You invest your time and effort in selecting the best resin for your projects. Have you thought about storing your epoxy resin so it stays at its best?
You need to.
Like you wouldn’t buy a super-expensive, overpriced sports car only to park it on the street. In a sketchy neighborhood. Under a broken light. Overnight.
Show the same love to your resin. Here are the 4 biggest mistakes about storing epoxy resin that you don’t have to make.
Mistake 1: Thinking you have forever to use your resin.
Epoxy resin generally has a shelf life of one year. Does that mean you should buy resin a year’s worth at a time?
No. Only buy enough resin you can comfortably use within six months.
Why? When you get to six months and a day, will you toss it out? No, of course not. It’s like telling yourself you need to leave at 4:30 knowing you won’t leave until 5. #itme
What about storing resin types other than epoxy?
Polyester resin only lasts six months. Some polyurethanes only have a shelf life of three months.
Mistake 2: Not knowing how long your kit has been open.
Who hasn’t bought resin supplies only to find them in a closet or box months later and think, “I totally forgot I had this.” Write the date you open your kit on the box. Then, keep a running tally of how much you’ve used somewhere conspicuous. It’s a reminder of what you’ve got open, the amount left, and how soon you should use it.
Mistake 3: Keeping your resin in direct sunlight.
The best place to store resin is in a closet in a climate-controlled environment. UV light exposure speeds up yellowing, and temperature swings form condensation inside the lids. Keep your resin in the dark and a temperature between 60 and 80 F.
What do you do if your resin yellows?
All resins eventually yellow. Besides UV light exposure, hardener yellows once it’s exposed to air. When you buy resin next time, switch to smaller size kits to use up a kit quicker.
💡 Pro tip: If you have yellow resin and it’s been well-stored, it will cure, but with a yellow tint. If you have a project that takes resin colors, this is a great time to use it. You can see what I’m talking about here: What to do with yellowing resin?
The good news is that a resin kit isn’t flammable, so you don’t have to worry about care instructions for resin catching on fire. Unless it gets too hot after mixing. Resin getting hot and smoking is a whole other problem.
Mistake 4: Throwing away the resin kit packaging.
Keep your original packaging. Besides instructions and manufacturer information, it may also have production/lot information. This may be important for resin troubleshooting with the manufacturer.
💡 Pro tip: Keep liquid resin products (resin, hardener, colorants, etc.) in a plastic bin. Then, should there be a leak or spill, it’s contained and not making an even bigger mess. #itmetoo
⚠️ If you’re tired of storing epoxy and don’t want it anymore, dispose of resin properly.
Feeling hesitant to get started with resin because you’re worried about making a mistake?
Or maybe you’ve already made a few, and you’re scared to try resin again. I’ve been there. I made lots of resin mistakes when I was a beginner. It was almost enough to make me give up on resin altogether. That was 15 years ago, and since then, it’s been my mission to fast-track your resin success.
It’s why I wrote the resin book for beginners, Resin Fundamentals. Instead of trial and error, you can learn from my mistakes. I share the important things you need to know to succeed with resin starting with day one. Buy the ebook now and get an email download link in minutes.
