Epoxy is a term used to describe a certain type of adhesive that has the ability to bond surfaces permanently. It can be used on many different surfaces as well, such as concrete, wood, metal, and stones.
Epoxy is heat-resistant and waterproof when it dries. Because it’s durable and long lasting, it can be used for just about any project you have in mind.
However, epoxy isn’t perfect. In some cases, you may find that you need to remove the epoxy from one surface or another.
This can be because of an application error or simply as part of your remodeling process. Before we get into how to remove epoxy from your flooring or other surfaces, let’s first take a look at a few details about this adhesive material.

How do you dissolve hardened epoxy?
You can dissolve hardened epoxy using either heat or solvents. My favorite solvent for dissolving epoxy is acetone, and it’s safe on most surfaces.
I use it to remove spilled blobs of epoxy before it cures, and I also keep a bottle handy in case a completed project needs some minor modifications.
The only downside with acetone is that it will damage plastic when you leave it on the plastic too long. This could be an issue if you’re using acrylic sheeting or similar plastics as the construction material for your project; but if you’re relying on heavy glue layers to hold the pieces together, the solvent softens up the glue without damaging the surface underneath.
If your epoxy is still fresh and hasn’t been cured yet, acetone will soften up the surface so you can scrape it up without scratching or dulling whatever surface you’re trying to protect.
Solvents like these are easy to find at any hardware store or home center just look around where they sell paint thinners and other sprayable chemicals (it should be next to the nail polish remover).
How do you remove or dissolve epoxy?
- Use paint stripper. Some types of epoxy resin can be softened with a strong paint stripper, which will allow you to scrape it away from whatever surface it’s adhered to.
- Use oven cleaner. If you’re dealing with a small epoxy spill, a regular oven cleaner can dissolve the bond between the epoxy and the surface it’s stuck to. Even though it normally states that you shouldn’t use oven cleaner on aluminum, in this case, it’ll likely work just fine!
- Use a heat gun or blow dryer. Heat is another effective way of softening epoxy so that it can be removed manually using tools like sandpaper or steel wool. You’ll need to use a heat gun or hair dryer on low heat and high air pressure for approximately one minute per inch (2.5 cm) of thickness in order to soften your resin enough to remove it.
- Use a strong solvent. Chemical solvents are designed specifically for dissolving glue-type substances such as epoxy resin and removing them safely without causing damage to most surfaces they may have come into contact with.*
Can cured epoxy be dissolved?
Yes, it can. But there’s a catch: the epoxy must be fully cured.
It is quite easy to remove uncured epoxy with a chemical solvent like acetone or an epoxy thinner. But once it has been cured, the process becomes much more difficult and complicated.
This is because of the cross-linking structure that develops within the resin as it cures, making it resistant to many solvents.
Acetone can dissolve hardened epoxy if given enough time (for example, if you soak something in acetone for twenty-four hours) but most other solvents will not work at all on hardened epoxy due to its cross-linking structure which makes it chemically resistant
Can you melt epoxy?
Most epoxies are thermoset polymers. Epoxy resins can be melted and poured, but the resulting material is a thermoset polymer, not a thermoplastic.
Thermosets cannot be melted and reshaped like thermoplastics can once they have cured.
Is there a solvent for epoxy resin?
- Methylene chloride
- MEK (methyl ethyl ketone)
- Butyl acetate
- Methyl acetate and
- Diacetone alcohol (this is a relatively weak solvent, but it can work).
What is the solvent for epoxy?
Epoxy is a very strong and durable product, but it may be dissolved using acetone. Acetone nail polish remover often is used to dissolve epoxy because it is highly concentrated acetone.
The epoxy will have to soak in the acetone for several hours before you’re able to wipe or scrape off the remainder of the epoxy.
Does vinegar dissolve epoxy?
Yes, vinegar will dissolve epoxy. The acetic acid in the vinegar is what acts as a solvent, breaking down the hardened epoxy into a gooey and easy-to-remove substance.
This makes vinegar an excellent solution for removing epoxies that have adhered to non-porous surfaces such as glass, metal, or countertops.
You will want to use it with caution on epoxy that has been applied or cured to porous surfaces like wood, however: the problem with using vinegar is that it can be difficult to clean up completely after you’re finished removing the epoxy.
Vinegar is a strong acid and should be handled with care; make sure your work area is well ventilated and wear protective clothing and eyewear while working with it.
If you are applying it directly onto porous surfaces such as wood there is also a chance that the vinegar will stain them.
How do you make epoxy thinner?
- Place the epoxy in a double boiler or improvised container, and melt it down until it becomes liquified. This takes about 15 minutes on average, depending upon the size of the epoxy.
- Add acetone to the melted epoxy, one drop at a time, until you’ve reached your desired consistency.
- Allow the mixture to cool before using it or pouring it into another container.
In summary, the best way to dissolve epoxy is by applying heat. However, this method can only be used if you have uncured epoxy.
If you have cured epoxy, then the simplest method for dissolving it is by using acetone or any other solvents that are specifically designed for dissolving epoxies.
However, there are some additional methods that you can use to get rid of cured epoxies from your property. For example:
- Melting it by using a torch or an oven
- Thinning it by adding water
- Dissolving it in vinegar
