If you’re a do-it-yourselfer, you’ve likely used epoxy at some point. Epoxy is a great way to seal and fill cracks in concrete or as an adhesive for tiles. But how should it be stored?
This article will show you the best ways to store your epoxy so that it’s ready when you need it!
How Do You Store Unused Epoxy
The first step is to understand the epoxy itself. Epoxy comes in two parts that are mixed together before use.
Part A contains a resin, while part B typically has an accelerator or hardener included to speed up the curing process of the mixture.
After this combination takes place, it can be stored for future use without any problem until you’re ready to start working with it again.
Epoxy should only come into contact with other compatible materials, so if you have many different kinds of tools and materials in your shop then taking inventory beforehand will help ensure there isn’t any cross-contamination during storage time between each product type.
Also, remember not all epoxies are created equal, some may contain more volatile chemicals than others which require more careful storage practices.
Regardless, epoxy should always be stored in a cool and dry place that is out of direct sunlight (which can cause the product to harden too quickly).
It’s also advisable not to store it near any open flames or heat sources like your furnace because this could lead to spontaneous combustion which will make for an unpleasant experience if you’re unprepared!
Epoxy typically has a shelf life between 12-24 months as long as it stays unopened and undisturbed at room temperature.
If you need more time before using your existing supply then consider transferring small amounts into smaller containers that are easier to handle such as glass jars with secure lids.
You may want to do this anyway if you plan on giving some away as gifts or using it in a different capacity. In any case, by following these simple tips you can ensure that your epoxy will be safe and ready to use when you need it next!

How Do You Keep Epoxy From Drying Out
Epoxy can be stored in a variety of ways, but the most important factor is in keeping it from drying out.
One way to do this is to store it in an airtight container with a desiccant, such as silica gel or rice.
You can also store epoxy in its original packaging if you’re careful not to let any air in.
Another option is to freeze the epoxy, which will keep it fresh for up to six months. Just make sure that you thaw it completely before using it!
No matter how you choose to store your epoxy, make sure to keep it away from heat and sunlight.
These conditions can cause the epoxy to dry out prematurely and become unusable. Epoxy that is stored in an airtight container with a desiccant will keep for several months to over a year.
Epoxy can be frozen and thawed up to six times without any loss of quality, but we still recommend using it within the first two years after purchase.
What Temperature Should Epoxy Resin Be Stored At
Epoxy resin should be stored in a cool, dry place. It can be stored in the refrigerator or freezer, but it is not necessary to do so.
The ideal temperature range for epoxy resin storage is between 50 and 90 degrees Fahrenheit.
Higher temperatures will cause the epoxy to cure more quickly, while lower temperatures will slow down the curing process.
If you are storing epoxy in a refrigerator, be sure to place it in an airtight container to prevent the resin from absorbing moisture from the air.
Epoxy that has been exposed to moisture will not cure properly and may cause problems with the final product.
If you are storing epoxy in a freezer, make sure the container is tightly sealed to prevent the epoxy from becoming frozen.
Frozen epoxy resin can be difficult to work with and may cause damage to your project.
Epoxy should also be stored in a dark place, as light can cause the resin to cure prematurely.
What Can I Do With Leftover Epoxy Resin
If you have leftover epoxy resin, your first thought may be to just throw it away.
However, there are a lot of things that can be done with this product! You might also want to purchase more epoxy for future use and store the remaining amount correctly so as not to affect its quality.
Here is how:
- If you’re using epoxy resin for small projects, it’s best to keep the leftover amount in a container and cover it with plastic to prevent drying. However, too much exposure may cause molding or stickiness so limit the opening of the cap as well.
- For larger amounts such as gallons, seal them tightly and store them inside covered bins away from sunlight and humidity at room temperature (between 65-75 degrees). Keep containers upright to avoid leakage. Don’t forget that even though epoxy is nonflammable, heat can still affect its quality, hence why exposed areas should be avoided especially when storing units near furnaces or other heating appliances.
How Do You Preserve Mixed Epoxy
Mixed epoxy will retain its effectiveness for up to one year, but it is best to use the mixed resin within six months.
If you are using small quantities of an epoxy system (for example, less than a quart) and intend on using or applying all of the product within several weeks, then storage isn’t an issue.
However, if you have larger amounts that won’t be used in time frames mentioned above or if your project schedule means that fresh batches must be made frequently then proper storage becomes critical to ensure efficient workflow without compromising your final results.
Does Tacky Epoxy Ever Cure
Tacky epoxy does not ever cure because it is wet. It can dry to a soft stickiness if left out for an extended period of time, but tacky at best.
Tacky means that there is still moisture in the resin which could cause problems with curing and strength so storage should be as recommended on the packaging or by your supplier.
If you have a hardener laying around from another project then it might be worth straining any solid particles out before using again since this could mess up future batches.
Why Is My Epoxy Hardening So Fast
The epoxy you are using has a very short pot life, which means that it will begin to harden quickly after mixing.
This is not necessarily bad news. If your project requires quick curing time or if there isn’t enough time for the epoxy to fully cure before being sanded, this can actually be helpful.
What Happens If You Add Too Much Hardener To Epoxy
If you add too much hardener to epoxy, the resin will become too brittle and prone to cracking.
This can cause the finished product to be unstable and unsafe. If this happens, you will need to remove as much of the epoxy as possible and start over with a fresh batch.
How Long Can You Store Epoxy Resin
Epoxy will last forever if stored properly, says Gorilla Glue’s website. If you are storing the bottles for an extended period of time, empty both containers and clean them thoroughly to remove any dust or particles that may have been collected in the container.
