how to remove epoxy paint from garage floor?

Epoxy paint is one of the most durable types of paint available. The non-porous surface prevents moisture from seeping through, making it ideal for garage floors and other areas that need to be protected from water.

However, as with any paint job, epoxy can eventually become worn out and needs to be removed before you repaint or refinish your flooring. Fortunately, removing epoxy paint isn’t difficult if you know how!

What dissolves epoxy paint?

You can remove epoxy paint from a garage floor using the following chemicals:

  • Acetone
  • Ammonia
  • Hydrochloric acid (or muriatic acid)
  • Sodium hydroxide (for high-strength epoxies) or potassium hydroxide (for low-strength epoxies)

How hard is it to remove epoxy flooring?

Removing epoxy paint from your garage floor is a difficult process. Before you get started, make sure that you have the proper tools and equipment.

You’ll need:

  • A chemical stripper
  • A pressure washer (if you don’t already have one)
  • A scraper (for removing paint from hard-to-reach places)
  • A heat gun (for softening hardened epoxy)
  • An angle grinder with a strong enough blade to cut through the thick layer of epoxy

How do you remove uncured epoxy from garage floor?

First, you’ll want to remove any uncured epoxy coating from your garage floor. This can be done with a paint stripper or scraper, but be sure not to use too much force or it will scratch the concrete.

A heat gun can also help loosen up the epoxy and make it easier to scrape off the floor. Next, you’ll want to clean up any remaining residue with mineral spirits or acetone using a shop vacuum or broom.

You should then wash down your garage floor with water and let it dry for 24 hours before applying another coat of epoxy paint overtop of what remained behind after scraping off all loose pieces of old epoxy coating that were left behind by previous owners’ DIY projects (or perhaps even yours).

After cleaning up all leftover debris from old coats of paint that may have been layered onto top of one another over time throughout years past–and especially if they’re peeling–you’ll want to apply several layers overtop one another until it becomes hard enough again so no more peeling occurs anymore.

How do I remove old garage floor coating?

There are four ways to remove old garage floor coating:

Use a heat gun to soften the epoxy. This can be done in two different ways. One way is to apply the heat gun directly onto the garage floor, which will cause the epoxy coating to soften and become sticky.

You can then use a scraper or some other tool of your choice to scrape away at this softened layer until it is removed completely.

The second way involves using a heat-resistant mat on top of your garage floor before applying an even coat of anti-skid material over it.

Once this has been done, you will need an industrial-strength heat gun (at least 1,000 watts) that can withstand temperatures up to 500°F (260°C).

This method works well for removing old epoxy from concrete floors because it does not require any scraping whatsoever; instead, just apply some water under high pressure so that it mixes with any residual adhesive still present after heating up with an infrared torch or other type of similar appliance designed specifically for this purpose only!

What is the best way to remove epoxy paint from concrete?

While there are several methods of removing epoxy paint from concrete, the best way to do so is with a concrete grinder.

To use a concrete grinder, you will need to rent or purchase one from your local hardware store. When using it on epoxy paint, be sure to wear protective goggles and gloves while operating the machine.

The first step in using a concrete floor scraper is to turn on your machine and let it warm up for at least 10 minutes before starting work.

Once it’s ready, sprinkle some water on any dry spots or areas of loose dust that may have accumulated on top of your garage floor since its last cleaning and sweeping session (this will help prevent dust from getting into your eyes).

Once all areas have been sufficiently wetted down with water, begin scraping away any loose pieces by placing them into buckets until they’re completely removed from both sides of each section being worked on—don’t forget about corners! Again: don’t forget about corners!

Does vinegar dissolve epoxy?

While vinegar is not a good solvent for epoxy, it does act as an acid. The chemical reaction between the acetic acid in vinegar and the epoxy chemical bonds produces a weak carbonic acid that helps to loosen up the bonds and make them soluble in water.

The more concentrated you make your solution of vinegar, the better it will be at dissolving your epoxy paint.

How do you remove old epoxy?

To remove epoxy from a garage floor, you can try a number of methods. Here are four different ways to remove it:

  • Using a Heat Gun

A heat gun can be used to soften the epoxy and make it easier to scrape off.

  • Using a Scraper

An old scraper may do the trick, but if not, try using steel wool or wire brushes as well!

  • Using Chemical Solvent

If all else fails, use chemical strippers such as Goo Gone or Goof Off (both available at hardware stores) that should dissolve the epoxy when applied according to directions on the bottle.

Can you paint over epoxy floor?

You can paint over epoxy, but it’s not recommended.

Theoretically, you could paint over the epoxy and get a decent result. The problem is that the paint may not adhere as well as it otherwise would on smooth pavement.

This means that you’ll have to be careful with the pressure washing, which could cause the new layer of paint to peel off or wear off quickly.

Another thing to consider is that because it’s already covered in epoxy, further layers of coating won’t bond well with what’s already there either—and this can also cause peeling and flaking down the line once your new coat starts losing its adhesion (which happens eventually).


Epoxy paint is a great option for your garage floor. It’s durable and easy to clean, but sometimes you may want to remove it and start over with another type of paint.
