Where should epoxy resin be stored?

In this article, we will take a look at where epoxy resin should be stored and what you can do if you have to deviate from the ideal storage conditions.

First of all: You should always store your epoxy resin in a cool, dry environment! In the best case scenario, it is placed on a shelf with an ambient temperature of 25°C (77°F) or less, with no direct sunlight hitting it and out of reach by children and animals.

Sounds easy enough, right? However, in practice it isn’t always possible to find such storage conditions. This can especially be problematic if you live in regions that experience high temperatures for most of the year. But don’t panic! We’ve got you covered with our tried-and-true tips and tricks for storing your epoxy resin safely away from all harmful variables – no matter where you are working from.

Where do you store epoxy resin?

  • In a cool, dry place
  • Away from direct sunlight
  • In a well-ventilated area
  • In a dust-free environment
  • In an airtight container
  • In an area where the temperature is between 50-70 degrees F.

Where should I store my resin?

  • Store your resin in a plastic storage bag. It’s important to keep oxygen and light out of the resin. A plastic storage bag is an easy, cheap way to do this. Use a heavy-duty bag so it won’t rip when you put the resin in it.
  • Place the storage bags into a storage box or container. If you have extra space, you can put all of your epoxy resin and supplies into a plastic toolbox, which you can pick up at your local hardware store for around $10 (or less if they’re on sale). In this toolbox, create compartments using cardboard boxes or paper towel rolls to keep different things separated. This will make finding everything easier later on!
  • Store these containers in a cool dry place away from sunlight and heat sources such as radiators or hot water pipes that might cause damage to them over time

Can epoxy be stored outside?

  • Can epoxy be stored outside?

Yes, but only in a cool, dark place and never under direct sunlight. The best place to store epoxy resin is indoors in a dry room that is not too hot or cold. If you have to store it outside, keep it in a dry shed or covered area that has some ventilation. Make sure the shed is away from direct sunlight so the temperature does not rise above 25°C (77°F).

What temperature should epoxy resin be stored at?

Generally speaking, the best place to store epoxy resin is at room temperature. This means that epoxy resin should be stored in an environment with a temperature between 18 and 20 degrees Celsius (64-68 degrees Fahrenheit).

You can store your resin at a warmer or cooler temperature than this, but you may notice that it sets up more quickly or slowly than expected. If you know that you will be working with your resin in extreme temperatures, it’s a good idea to let it sit at room temperature for 24 hours before use so that it has time to acclimatize to its surroundings.

That said, if you are working in particularly warm weather (20+ Celsius) we highly recommend keeping extra hardener on hand so that you can adjust the mix ratio as needed.

The exception to all of this is epoxy resins which have been exposed to high temperatures – especially hot direct sunlight. These resins should not be used as they have likely begun curing and will not perform correctly when mixed and applied.

Can resin go down the sink?

Why not? Well, there are a few reasons.

First and foremost, epoxy resin is toxic. While the final cured product is not dangerous, the liquid resin and hardener should be kept away from your skin (and lungs) in their uncured state. If you do come into contact with them, it’s important to wash with soap and water right away.

Second, epoxy resin isn’t good for the environment. It can contaminate waterways through run-off or carelessness and clog up water treatment plants if it gets poured down the sink or flushed down a toilet. Resin is also toxic to aquatic life so we should be careful not to spill any on our floors where it could find its way outside to a river or lake nearby. And finally, epoxy resin will go bad if exposed to ultraviolet light so storing it somewhere dark like a closet or under your bed will help extend its shelf life!

Can resin be kept in sunlight?

Resin should be kept in a cool, dry place away from direct sunlight. The quality of the product can degrade over time, so you want to keep it in a place that isn’t going to expose it to too much heat or moisture. The problem with sunlight is that it contains UV light, which can negatively affect the epoxy resin. If you need to store your resin outside, make sure you put it somewhere shaded like under a table or umbrella.

When the epoxy resin is stored properly and its shelf life has not expired, then using it will no longer be an issue!

How do you store open epoxy resin?

It’s important to keep your epoxy resin out of the sun, away from heat sources, and in a place that won’t get too cold. The same goes for storing it near strong smells, as your epoxy will start to smell just like that. If you want to use it again later though, it’s best not to leave it open for more than a week.

  • Don’t store open containers of epoxy resin in sunlight or somewhere hot like near a heater or radiator (or on top of your fridge).
  • Avoid putting the open container in any cold places that might freeze it or make it harden early.
  • Be careful about inadvertently placing the open container near anything with a strong smell.

How do you store 2 part epoxy?

There are some important things to keep in mind when storing epoxy resin, which we’ll go over below. If you make sure to store your epoxy properly before you use it, your project will turn out better and you may even be able to reuse resin that you’ve already used.

  • Store epoxy in a cool place with good ventilation. Epoxy should ideally be stored at a constant temperature between 15 and 25 degrees Celsius (60-80 degrees Fahrenheit). The best place to store it is inside a house or building where the temperature is kept relatively stable by climate control equipment. A garage or attic where the temperature fluctuates widely is not suitable because of this potential variance.
  • Keep away from sources of heat or flame: Like most flammable materials, enough heat applied over time can cause epoxy resin to be consumed by fire. Do not store epoxy directly next to a heat source like a furnace or radiator, and do not keep in an area where there could be open flames (like an oven or near candles).


You now know exactly where you should store your epoxy resin to ensure it lasts a long time. Epoxy resin that is stored in hot, humid conditions can be ruined in a short amount of time. That wasted resin will cut into your wallet and set back the progress of whatever project you’re working on.

It’s not worth saving money by storing your epoxy resin in subpar conditions. Take the extra step to make sure you keep it safe, so you can use it later when you need it.
