Epoxy is a powerful adhesive that can harden quickly. Once it’s cured, it can be difficult to remove. Epoxy resin adheres strongly to surfaces and has a high solvent resistance, which makes it ideal for use in construction and other industrial applications.
But if you’re trying to remove epoxy from an object or material, such as PVC pipe or wood, you may need to find an alternative method of removal.
This article will cover common ways of removing epoxy from objects and materials like plastic pipes so that you know what options are available when faced with this problem.
How do you remove epoxy from a pipe?
There are several ways to remove epoxy from a pipe. You can use a razor blade and some elbow grease, or you can use a heat gun to soften it and scrape away the excess.
If that doesn’t work, you could try using a solvent or chemical to dissolve the epoxy and wipe it off with a rag.
Before you start scraping at your pipe though, keep in mind that this method is not recommended if you’re working with PVC pipes because they tend to crack when scraped hard.
Instead of going at them with an abrasive tool like this, one would suggest, trying using other methods instead like those listed above (solvent/chemical).

What dissolves dried epoxy?
You can remove hardened epoxy with acetone, which is a chemical solvent that dissolves the hardened epoxy resin. Acetone is commonly used as an ingredient in nail polish remover and may be found at most drug stores.
Acetone is a common chemical solvent that can dissolve the hardened epoxy resin in PVC pipe. It will also dissolve PVC pipe itself, so use caution when using it on your pipes!
What chemical can dissolve epoxy?
The best solvent for dissolving epoxy is acetone. Acetone is easily available at most hardware stores and can be used to dissolve a wide range of materials, including many types of epoxy.
It should be noted that the use of acetone may result in damage to PVC pipes if they have been exposed to significant amounts of heat or pressure.
To dissolve the epoxy glue, simply take some acetone (or another solvent) and apply it directly onto the glue. Swirl it around with your finger until all traces are gone. Repeat as necessary until all traces have been removed.
Does vinegar dissolve epoxy?
Vinegar is a weak acid and will not dissolve epoxy. Vinegar contains acetic acid, which is a very weak organic acid.
While it’s possible that vinegar could have an effect on the surface of your PVC pipe, it will not remove the epoxy coating in any way.
The vinegar would need to be stronger and more caustic than just normal vinegar to dissolve the epoxy coating and soften it so that you can rub it off with sandpaper or scrape it with an old credit card.
How do you remove cured epoxy from plastic?
If you’re working with a plastic that is not PVC, you probably don’t have to worry about the epoxy bonding to it. Instead, you can use a razor blade or other sharp tool to scrape off any cured epoxy.
You can also use a solvent on clean plastic surfaces to dissolve the remaining uncured epoxy or soften cured epoxy so that it can be scraped away.
While this won’t remove hardened cured epoxy from PVC pipes, it will work for other plastics like ABS and PMMA.
How do you soften epoxy resin?
There are a few ways to soften epoxy resin. The best way is to use a solvent, but you can also try heat or freezing.
To soften epoxy using a solvent, you’ll need something like acetone or MEK (methyl ethyl ketone). The process works like this:
- Soak the object in acetone for about 15 minutes
- Scrape off excess material with a putty knife
- Rinse with water and let dry
How do you break down hardened epoxy?
The best way to remove epoxy is with a heat gun or propane torch. A hairdryer won’t be able to get hot enough and will take forever.
With the heat gun or propane torch, hold it about six inches from the surface of the pipe for about three minutes. After heating up your PVC pipe, use a putty knife to scrape off as much residue as possible—you may need another person’s help in this step!
If you’re still having trouble removing all of the hardened epoxies, repeat these steps until all of it has been removed from your PVC pipe.
Will acetone remove cured epoxy?
Acetone is a solvent, not a solvent. It’s pretty aggressive and can dissolve many things, but it won’t remove epoxy from PVC pipe. Acetone will soften the cured epoxy coating on the pipe, but not enough to actually remove it.
You would have to sand or scrape off the hardened epoxy first before attempting to dissolve it with acetone or other solvents like methylene chloride and trichloroethylene (TCE).
That’s all we have to say about removing epoxy from PVC. You now know how to dissolve the hardened resin in your plastic pipes, and you can use this information for all sorts of projects.
