Importance of Proper Storage
Storage conditions play an integral part in keeping epoxy glue effective over time, and proper storage conditions help you avoid having to discard expensive products due to poor storage practices.
Temperature fluctuations (hot or cold), exposure to moisture/humidity or light/UV radiation and light can all have detrimental effects on epoxy glues, leading to their failure even for surfaces with stringent requirements such as woodworking applications. Therefore storing them properly at stable temperatures away from direct sunlight in sealed containers will keep their chemical properties effective over an extended period while simultaneously being safe to use.

How to store epoxy glue: Best Practices
Keeping it in a cool, dry place
Temperature should always be considered when it comes to storing epoxy glue, in order to avoid its degradation or premature curing. For optimal storage results, ensure it remains at cool room temperatures or below.
Temperature matters; too warm may cause epoxy resin to begin curing and hardening in its container, rendering it useless for use. For optimal shelf life, epoxy glue should be stored at around 21°C (70°F) for best shelf life results and to avoid epoxy glue problems when using it.
Storage should not take place near heat sources such as heaters, ovens or direct sunlight as such high temperatures could accelerate curing processes and result in thick epoxy glue which becomes difficult to work with.
Sealing the container tightly after use
Once using epoxy glue, it’s important to seal its container securely to avoid air entering and reacting with any uncured resin or hardener left inside, which could potentially trigger premature curing and render your remaining adhesive unusable. Some people find storing their epoxy upside-down can help keep air away.
However, this method may not work well when dealing with larger containers with multiple compartments or those which contain adhesive residue around their lid. No matter which storage solution you use, make sure any excess glue from around its seal has been cleaned off prior to tightly sealing it back on.
Using a desiccant or silica gel packet to absorb moisture
Moisture can quickly degrade epoxy adhesive over time. To keep it from hardening prematurely and breaking down too soon when stored – particularly if living in humid areas – use desiccant packs or silica gel packets in your storage container to maintain dry storage conditions.
Desiccant packets contain materials like clay or silica gel that absorb excess moisture from their environment and help ensure an adhesive stays dry by drawing moisture out from its surroundings. Simply drop one or two packets next to your epoxy container for best results in keeping moisture issues away.
Avoiding exposure to direct sunlight or fluorescent light
Avoid direct sunlight and fluorescent lighting when it comes to epoxy glue storage, as both types can cause the resin to yellow over time and become more brittle, lessening its overall effectiveness as an adhesive. Instead, store in an ambient cool dark area away from any light sources.
If you must use epoxy in brightly lit areas, using UV-protective glasses or tinted shields to shield its adhesive can extend its shelf life while saving both time and money in the long run. By following best storage practices you’ll extend its effectiveness while saving both time and money in long-term storage options.
Specific Storage Tips for Different Types of Epoxy Glue
Epoxy glue comes in two varieties; one-part and two-part epoxy. One-part epoxy is pre-mixed adhesive that typically comes packaged in tubes or bottles for convenience.
Two part epoxy glue contains two components; epoxy resin and hardener which must be mixed prior to application. Different types of 2 part epoxy glue for wood require various storage solutions in order to preserve its effectiveness.
One-Part Epoxy: Store at Room Temperature, Away from Heat Sources
One-part epoxy glue should be stored at room temperature, away from radiators and heaters as exposure to excessive heat could cause it to harden into an ineffective form and harden into unusability. Furthermore, upright storage positions will prevent it leaking or drying out quickly.
If you live in an area with high humidity levels, consider placing one-part epoxy adhesives in an airtight container or bag equipped with desiccant packets to absorb any extra moisture that might form over time. When possible, avoid placing close proximity of chemicals or solvents that might break down their integrity over time and break the adhesive down over time.
Two-Part Epoxy: Keep Separate Containers in a Cool, Dry Place
Two-part epoxy should be kept in cool, dry places that are shielded from direct sunlight or fluorescent lighting sources as exposure to light may impact its curing time and strength. Before bringing two-part epoxy together with the stir stick in your mixing tray, ensure both containers have been stored at room temperature for several hours prior to being mixed together.
Once mixed together, use within the time indicated on its packaging before it begins to cure. To know more about the drying and curing time of epoxy, check out this article. Be sure to store separate containers tightly sealed when not being used since moisture exposure could render them unusable over time.
If your project requires only small quantities of adhesives, consider separating what you require into individual containers rather than leaving all your stockpile exposed to air and moisture. By following these storage recommendations you can extend its shelf life, guaranteeing you always have reliable glue when needed for projects of all sorts.

Common Mistakes to Avoid When Storing Epoxy Glue
Leaving the container open or partially sealed
One of the biggest mistakes people make when storing epoxy glue is leaving their container open or only partially sealed after use, leading it to harden and become useless. Always ensure you close and tightly seal after each use – even if just taking a short break!
If you are using two-part epoxy, be sure to keep both containers tightly sealed until you’re ready to use them. If an accident occurred and epoxy glue hardened in an open or partially sealed container, don’t immediately discard it as this might still have some use in other projects!
Add small amounts of acetone or rubbing alcohol to the glue mixture in order to thin it and make it usable again, but keep in mind this could compromise its strength and quality, so for best results it’s wisest to seal all containers properly in the first instance.

Storing it near chemicals or solvents
People commonly make another misstep when storing epoxy glue: keeping it near other chemicals or solvents that could react unexpectedly with it and alter its properties or even cause it to ignite spontaneously. To mitigate the risk, keep epoxy in an isolated cabinet or location away from any hazardous substances.
If there are no other solutions in your workspace for storage of epoxy glue, consider investing in an airtight container with an airtight lid as this will protect it from potential dangers such as moisture. It also prevents any unintended reactions between epoxy glue and other substances nearby that might lead to reactions between it and their containers.
Not checking the expiration date
Many individuals forget to verify the expiration date on epoxy glue before purchasing or storing it for future use or storage. Due to its chemical makeup, crystal clear epoxy glues have limited shelf lives that may become less effective over time.
Checking the expiration dates on epoxy glue containers before storing or using them to ensure their usable lifespan is still within acceptable parameters is key to making sure you receive an efficient product that lasts as expected and doesn’t become less effective, take longer to cure, or fails to form proper bonds.
Avoid ineffective glue by disposing of expired epoxy according to local regulations and maintaining regular checks of its expiration date, so your epoxy remains fresh for when you need it the most.
