How To Remove Carpet Glue From A Floor?

Removing carpet glue residue from concrete is relatively easy, and all you need to do is follow all of these steps carefully.

  • Manually scrapping off excess glue
  • Soften adhesive using boiling water
  • Applying glue remover
  • Using an iron to remove left over glue

Remove Glue Mechanically

The first step is not using a carpet glue remover but rather removing all the glue with a sharp razor and making sure to scrape off as much as you can mechanically.

This way, you will make sure all the carpet glue that is extremely strong will get removed from the concrete floor, and only the stubborn glue will stay.

However, most of the glue will get removed, and now you can proceed to use some other removers.

Use Boiling Water

The easiest way to remove the most stubborn carpet glue from concrete is by getting it dissolved with extremely hot water.

Boil water in a large pot and then pour it over the places where the glue has stayed – once you do this, make sure the water stays on these places for at least 2 minutes so they can start dissolving.

The adhesive should soften, and once a few minutes have passed, you should get a scrubber to try to get rid of those remains.

Most of the glue should disappear after it has spent enough time in hot water, but in case this doesn’t seem to be working for some parts of it, there are some other steps you will need to take.

Even if it doesn’t disappear c completely, it should loose glue and make the floor surface easier to scrap, so in general, it can be pretty useful.

Get A Glue Remover

In case you weren’t able to get rid of all the glue with boiling water, I would recommend you to find a heavy duty glue remover and bring on the work.

Some people will choose commercial glue removers, while others will stick with mastic removers, but you should choose what works best for you.

You can even create a glue remover by mixing some liquid detergent with ammonia solution, which is used to remove extra stubborn stains.

It will turn into a soapy liquid, and you will be able to use it even on the concrete subfloor, but make sure you always use rubber gloves because you don’t want to damage your hands.

This should work on most stains, but in case even ammonia can’t help you get rid of a sticky residue, you will definitely need to invest in some commercial glue removers.

There are plenty of options made specifically to help you remove carpet adhesive, and you won’t even need to use a razor scraper.

Always wear rubber gloves when dealing with old carpet glue, especially if you are using a commercial glue remover because it can cause burns on your hands, and I am sure that is not the result you want.

Try With An Iron

Even though you may be surprised why someone would recommend ironing concrete glue, the truth is this is also one of the options to get rid of residual glue easily.

You will need to place a regular paper on the glue patch on your concrete floor and make sure it doesn’t have any wrinkles, just like you would do when ironing clothes.

Make sure the iron is very hot and glide it in a straight way over the whole paper and repeat this move several times.

After you have ironed the patch several times, you can remove the paper and try to get rid of the scraper blade because it should have softened.

In case the glue is a bit softer but persisting, I recommend you do this a few more times.

If you combine this process with a scraping tool, I believe you can eliminate residue glue quickly, but if you need to remove glue from concrete floors in plenty of different places, then it can take you a long time and energy, so it may not be the best choice.

Floor Sanding

Last but not least, one option for removing glue is floor sanding which can only be used on clean concrete floors.

This is the most efficient way to do it, especially if there are several concrete overlays of dry glue on your floors.

It will help you get rid of both the top overlay and the hardcore glue that tends to stay in the pores, so the sanding disk can help you get rid of several problems at once.

However, you need to be quite careful with this one because if you go overboard with sanding floors, the process may get quite tough, and the odor will be horrifying, so you want to keep it slow and eliminate potentially dangerous fumes.

Is This Everything?

These are pretty much all the options you have to remove glue from concrete floors and not destroy it so much that you need new flooring.

As you can see, there are several options to get rid of all the residue glue, and no matter how stubborn it may be, these floor scraper and commercial glue removers should do their job.

In case none of these options have helped you get rid of the glue, and you have no idea how to solve the problem, then the only solution for you is to find a professional with a heat glue remover and hope that they will be able to solve your problem once and for all. You also may want to consider using professional machines for cleaning the house, as there will likely be plenty of residue laying around after the job is complete. However, this will depend on what fits your budget.
