It is common for carpet glue to remain behind after it has been removed from concrete subfloors. This can be bewildering for anyone who has ever had to go through it. The adhesive on a carpet is very stubborn and can be difficult to remove. It is best to remove the glue from the floor as it can accumulate grime.

You can remove carpet glue from concrete floors. You only need the right tools and methods for the job. These are the steps we recommend.

Step 1: Scrape off the concrete glue

Remove as much concrete glue as you can. Use a sharp-edged scraper to remove the concrete glue. You will need to use elbow grease.

This step can often be sufficient to remove all concrete glue. You will have to remove any glue bits that may have gotten stuck and then move on to step 2.

Step 2: Heat boiling water

You may be able to boil some water to loosen the glue depending on its age and the glue you used. You will need a large pot if there is still glue on the concrete. Allow the hot water and glue to mix for about 1-2 minutes.

Boiling water is the best option as it is cheap and has no toxins. Boiling water is a great option as it's free and can be used to make severe burns. Slowly pour the boiling water out from the pan.

Step 3: Remove any glue that has dissolved

Use a concrete floor scraper to remove the glue. Add more water to the concrete floor and continue with the scraper.

Step 4: Use glue remover

You can remove the glue using hot water but not all of it. Next, you will need to use a heavy-duty glue remover or mastic remover. Adhesive removers can chemically soften the glue, but they can also be dangerous, so make sure you have plenty of ventilation. Also, be sure to carefully read all labels, including warnings and directions.

Continue to remove excess glue with the straw scrubbing toothbrush or the scraper.

Step 5: Sand the floor

It is important that you have removed all glue from concrete pores. Acid stain can't penetrate concrete pores if the glue is not removed. Sanding the floor is a smart idea.

You can rent a floor sander or use a floor buffing machine equipped with a sanding disc. To remove the bulk of glue, use an aggressive grit. Next, switch to a finer grind (around 300 grit) to finish sanding the floor.

Don't go too deep with your sanding, as you might expose the aggregate. Sanding concrete will make it porous and allow it to absorb more sealer and acid stain.

Step 6: Troubleshooting

You can continue to troubleshoot if you still have trouble removing glue despite having tried the above methods. Use a heat gun to simply melt the glue. You can also use an iron if you don't have a heat gun. Use caution when ironing. Cover the glue with a towel before applying it.

If you still have glue marks, you can apply a highlight coat or scored pattern to cover them. You can also mix and use watercolor paints between sealers to hide the residue.

A word of advice on carpet adhesive strips

The tack strips are used to secure the carpet along its outer edges. They are usually nailed into concrete. The tack strips can leave a small gap where concrete nails have been removed. Concrete patching materials can be used to fill the gap, but they will stain the floor a different color. This creates a new problem.

We do not recommend patching the holes. Instead, you can continue staining concrete. After cleaning the flooring, apply the sealer and fill in the tack strips holes with clear epoxy. This will allow the stain to show through and also level out the surface so that the dive is gone. Make sure you blend the epoxy patch's top with concrete to avoid creating a small bump.
