It’s important and useful to know how to clean concrete under the carpet. Because the carpet remains glued with the concrete, after removing it, you’ll see the glue here and there on the concrete. You need to get rid of the sticky or cured glue as soon as possible by adopting several materials and products.

Also, you need to make the floor even and smooth without any residue to install another design on your floor. To do all these procedures, follow the next ways properly.

Way 1: Know the Materials:

The first job that you should do is to know the materials the whole procedure requires and then get busy collecting them. The materials we are going to use here will surely be available so you don’t have to trouble much. The materials are given below,

  1. A hand-held floor scraper
  2. Broom or light vacuum cleaner
  3. Hot water
  4. Towels or rags
  5. A floor scrubber
  6. Adhesive remover
  7. A cleaner
  8. A mop and bucket

Way 2: Scrape off the Adhesive:

Scrap the Concrete Floor by floor scraper

After you collect all the materials, you need to get into the job of scraping adhesive at first. The cured adhesive is so stubborn that it will require a strong hand-held floor scraper. This floor scraper comes with an edgy blade that helps in scraping off the dry adhesive to a large extent.

Besides, the long extension of the handle eases your job and prevents you from bending much. Thus, you can save yourself from back pain. Though scraping off hard adhesive requires some hard labor, the handheld floor scraper saves you from a lot of labor.

Way 3: Clean the Dust:

After you scrape the adhesive, it is time to clean the dust of the adhesive. For cleaning, you can simply use a broom and place the dust on a dustpan. This way the glue chunk and dirt will be removed properly.

But if you want less work to be done, then you can use a light vacuum cleaner instead. This will suck all the dust and debris in it and make your concrete ready for applying the cleaning solution.

Way 4: Remove the Remnant:

Well, as we’ve already said that it’s not easy to deal with cured glue only by scraping, it requires more to fully come off. To remove the remaining adhesive you need to boil some water. As boiled or hot water is more of a safe option than other many chemicals, using it would be a better option.

Spread the boiled water in places where you see stubborn glue. You can directly pour the boiled water on it or use a rag or towel instead of the direct throw. If you use a rag or towel, then there is very little risk that the floor will be affected by it. Let the adhesive soak the boiled water and loosen its bonds within 5 or 6 minutes.

Way 5: Time to Scrub:

The moment you notice that boiled water has loosened the molecules of the adhesive, you need to scrub the spot instantly. Do not wait for a long time to do the scrubbing process. It’s because, once the hot water is cooled, it will make the adhesive more strong rather than loosening the bonds.

Therefore, do the scrubbing process as soon as the boiled water loosens the bond of the adhesive. Adopt a floor scrubber for flooring and scrub the spot with all your energy because this is what your concrete floor needs to be free of adhesive fully.

Way 6: Apply an Adhesive Remover:

It’s actually frustrating that sometimes boiled water is not enough to remove the carpet glue out of the concrete floor completely. In cases like that, you need to ask for the help of chemicals that you’ve been saving for the crucial moment.

In case you fail to cover the job with boiled water, adopt acetone, goo gone, or any favorable adhesive remover. These heavy-duty adhesive removers are great for removing mastic glue within minutes. But before applying these hazardous chemicals, wear a safety suit and make sure there is enough ventilation system.

Way 7: Repeat the Process if Need:

This next step is totally optional. If you see that the adhesive remover is not doing its job in the first attempt, then go for the second or third or many more. You need to continue the process several times until the adhesive is totally gone.

Also, make sure the residue of the adhesive gets also affected by the adhesive remover that you are applying over and over on the concrete floor. As concrete provides a hardened surface, the chemicals will not damage the floor.
