Why It’s Important To Clean Concrete Floors After Removing Carpet?

Cleaning the concrete floors after removing the carpet is essential to keep the floor good and healthy. The adhesive and dust settled there can ruin the look of the floor. So, if you plan on not using a carpet anymore, it won’t look good as the surface will contain the adhesive.

Also, if the adhesive is stuck on the floor, it will be hard to walk over it. Sometimes, they might even cause people to stumble and fall. The overall look of the surface won’t be pretty to look at. And it will dismiss the beauty of your household.

Another thing is if you have pets or children at home, they may pick up the adhesive and dust from the floor and eat them. This is unhealthy and gross at the same time. So, to avoid all these issues, it’s better to keep everything clean.

How to clean concrete floors after removing carpet

A carpet is attached to a concrete floor by using adhesive or glue. Unfortunately, when you remove the carpet, the adhesive does not come off with the carpet in all areas. In fact, often, if left behind, some dried glue stains. These dried adhesives bonded to the floor in such a way that they seem impossible to remove. But by following some specific steps and the right tools, you can get the job done. Here are the recommended steps to take.

Step one: Scrape the adhesive

After removing the carpet, you will find plenty of dry glue marks on the floor. At first, you need to scrape off the concrete glue as much as possible. You should use a handheld floor scraper for this job. Handheld floor scrapers come with sharp blades that can effectively separate the adhesive from the concrete. Once you remove all dry glue, you need to sweep away the glue chuck.

Step two: Use a vacuum

Use a broom and a dustpan to sweep the floor. You need to remove all dust and debris along with the glue chunk. For better cleaning, use a light vacuum with a vacuum’s floor attachment. The floor should be completely free from all residue, dirt, and dust before applying a cleaning solution.

Step three: Apply boiling water

Boiling water can help for removing the rest of the dry glue from the concrete floor. You just need to apply a pot of boiling water to the dry glue to loosen it up. The amount of boiling water you use will depend on the specific glue used and its age. If still there is a significant amount of glue residue, you may have to use a large pot to boil enough water. Let the boiling water mix with the adhesive for 1-2 minutes.

Experts recommend using boiling water as it is the cheapest option and does not have any toxins. But you should remain very careful as a splash of hot water can burn your skin.

Step four: Scrub out the loosened adhesive

Boiling water will loosen the rest of the adhesive on the floor. Use a concrete floor scrubber to remove the moistened glue or do this job with the scraper.

Step five: Use glue remover

We hope the hot water can remove all the dry glue from the floor, but unfortunately, if it is unable, then you may have to use some heavy-duty glue remover or a mastic remover. The heavy-duty adhesive removers will chemically soften the residue and effectively remove them, but they are hazardous. If you have to use it, then adequate ventilation is required.

You should wear hand gloves, a mask and glasses to protect yourself. Do not forget to read the product labels, including warning, caution, and direction, carefully before applying.

Step six: Troubleshoot

If your glue residue is too stubborn and appears on the floor after trying all the above-listed methods, then you may need to go for something extreme. One option is still available; you can use a heat gun to soften the residue. If you do not have a heat gun, then you can also use an iron. You should be very careful to use iron, and you must cover the glue residue on the concrete floor with a thin towel before use.

If all of your efforts fail and some glue marks still appear, then you should try to use a highlight coat, multiple color scheme, scored pattern, and cover the residue.

Step seven: Mop the concrete floor

Take about one gallon of water in a bucket and add 2-3 teaspoons of liquid dish soap. Mix them well and use them for mopping the floor. Thoroughly mop the floor to remove all dust and dirt and make sure that you do not leave excess water on the concrete floor during mopping. Replace the water with clean water if it becomes too dirty.

Step eight: Dry the floor

After mopping the entire floor, it needs to dry completely. You should leave the floor to air dry overnight before performing any new installation or re-carpeting over top of it. If you leave it wet or saturated, then it can create a mildew problem.
