Does Elmer’s Glue Expire? Here’s How to Make It Last Longer…
If you’re a fan of crafting, you probably have an old bottle of Elmer’s glue sitting in the back of your craft drawer. While many crafters can use old glue bottles, it’s a good idea to find out if this kind of glue can expire and how long its shelf life actually is.
So, does Elmer’s glue expire? Elmer’s glue does expire. It can last from 8 to 12 months under normal conditions. It mainly depends on how often the glue is used or exposed to air and the conditions it’s stored in. To make the glue last longer it’s recommended to seal the bottle and store it in a dry cool location.
Keep reading to learn more about what Elmer’s glue is made of, how long it can last before expiring, and how to make it last longer.
What Is Elmer’s Glue Made of?
Elmer’s glue is made from polyvinyl acetate polymers combined with water and other chemicals like ethanol and acetone. It is also known as PVA glue or white glue
It comes in a liquid form due to the presence of water in its composition which acts as a solvent. Once it is applied to a surface, it will be exposed to air and the water will evaporate leaving the PVA polymers to bond with the surface.
This kind can be used for many applications and projects as it bonds well with different kinds of surfaces including wood, metal, ceramic, foam, and various kinds of paper. However, it doesn’t bond as well on smooth surfaces like glass and some kinds of plastic such as polypropylene or polyethylene.
How Long Does Elmer’s Glue Last Before Expiring?
On average, Elmer’s glue can last from 8 to 12 months before expiring.
However, keep in mind that the shelf life of any kind of glue depends on multiple factors, including how often the glue is used or exposed to air and the conditions the glue is stored in.
Unopened and unused glue bottles tend to last longer than opened and frequently used bottles.
How to Make Elmer’s Glue Last Longer?
Since Elmer’s Glue is considered essential crafting too, so it’s a good idea to know how to make it last longer
Here are some tips that would help you extend the shelf life of your glue:
- Always keep the glue bottle sealed tightly when you’re not using it to reduce the glue’s exposure to air and prevent it from drying. If you lost the bottle cap cap, you can use clear tape or another adhesive sealant to cover the opening of the bottle.
- Store unused and sealed tubes glue bottles in a cool, dry location where they will not be exposed to moisture, direct sunlight or any excessive heat.
- Try to use up your opened and frequently used glue bottles first and save any unopened bottles for later use.
Will Elmer’s Glue Dry Inside Its Container?
Elmer’s glue will dry inside its container if it’s left open as exposure to air for a long time will cause it to lose its moisture. You might be able to soften the glue inside the container by exposing it to heat, however, it will not be able to bond as strongly when applied to a surface.
Can You Use Expired Elmer’s Glue?
You cannot use expired Elmer’s glue. If the glue is past its expiration date, it will lose its adhesive properties and will not be able to bond effectively when applied to any surface. So, it’s recommended to use the glue before it expires and make sure to discard any expired glue bottles properly.
Can Mold Grow on Elmer’s Glue?
Mold can grow on Elmer’s glue. That is because Elmer’s glue contains a degree of moisture and oxygen that’s normally required for mold to grow. It’s highly recommended not to use glue that has any mold growth as it will not bond effectively with the surface. It can also cause some health problems.
Is Elmer’s Glue Toxic?
Elmer’s Glue is not toxic as it contains completely harmless ingredients. It is safe to get on bare skin and it doesn’t emit any kind of fumes when applied to a surface so it’s safe to inhale. However, it’s not recommended to ingest any amount of the glue as it might cause some health problems.
