Procedure to Remove Carpet Glue from Concrete

Concrete floors are getting more popular. However, glue residues from the old carpet can create a sticky, filthy mess that will keep you from painting or taking advantage of the concrete. This method is one of the most popular and environmentally friendly ways to remove glue remnants.

Step 1: Gathering the Tools

You will require several tools to complete glue removal, many of which are probably already available. This includes:

  • Pot or bucket of boiling water
  • Scraper (such as a spackling tool, hoe or)
  • Broom to push
  • Protective gear (rubber boots, rubber gloves, goggles)

Step 2: Scraping Down

Start by using the scraper to remove all the remnants and carpet pieces as you can. Utilize the push broom to remove the particles.

Step 3: Soften the Glue

Be sure to wear appropriate clothing. Put the boiling water on the floor and allow it to sit for a few minutes. Be cautious not to allow the water to cool too much, or the glue may get harder.

Step 4: Removing the Softened Glue

Use your scraper to gently work beneath the glue so you don’t damage your concrete’s surface. If you have a particularly difficult spot, such as those that are difficult to work on, you may require more boiling water to help melt the wax.

Step 5: Cleanup

After the glue has been thoroughly scraped away, wipe off any water left behind using a mop or towel, after which let the floor dry. Clean up any debris left so the cement is dry and ready to use.

Remove Carpet Glue From Concrete using Acetone.

Acetone is another great way to take concrete glue off your flooring. This amazing product removes the sealer from metals such as brass and will have no problem removing pesky adhesives. Since Acetone is an extremely powerful product, choosing the correct equipment to clean it is important.

Supplies you need: 

  • Acetone
  • Old toothbrush
  • Plastic container made of plastic
  • Mask
  • Old washcloth

If the area isn’t properly ventilated, wear a mask while cleaning scrub cement with acetone to avoid breathing the harmful fumes. Begin by immersing one of your old brushes in a small amount of acetone. Rub the subfloor area with the brush and acetone until the glue is eliminated or is only a little.

This step should take away the majority of the carpet glue. After that, you can remove any remnants of adhesive using a washcloth. Because acetone has bleaching agents, do not use it as a routine carpet cleaning product. However, you can use it on your subfloor before adding new carpeting is acceptable provided the subfloor is well-maintained before use.

Acetone may aid in the removal of mortar from concrete. Make sure you wear gloves to safeguard your hands.

Are there any alternative methods available?

If manual methods fail to produce results, don’t give up. There are at least two other methods that are often efficient for the job you’re working on.

  • Think about using a Portable Steam Cleaner. It is a tool you can most likely lease from the local Home Center. Make sure you direct the steam just a few inches away from the glue on your carpet until the glue is sufficiently soft to be scraped. Also, you can alternate steaming and scraping tiny sections at a given time to move the carpet glue before it cools and hardens again.
  • If you’re dealing with a large space and a particular type of carpet glue, you can use a cutting saw equipped with an attachment for scraping to do the task. Its circular saw will dramatically cut down on the time you spend scraping – the vibrating blade does the hard work to do work for you.
  • Scraper blades for reciprocating saws are available online and in most home improvement centers. To utilize the scraper attachment, insert the blade into the reciprocating saw and secure the blade in place. If the attachment for your scraper has an edge that is beveled and a flat edge, place the blade in a position where the beveled edge is facing the ceiling while the flat edge is facing the floor. Keep the saw in a low position. Then start to run it at half speed before ramping up to full speed. Carpet glue should be lifted right away!

Tips and Tricks

  • Being aware of heating the glue will help make it simpler to get rid of. When the glue cools to its original temperature, it becomes more brittle and more difficult to remove. So, make sure you treat a small part at a.
  • WD-40 can be extremely effective in taking carpet glue off of concrete flooring. Spray a bit of DW-40 on the area affected and allow it to set for approximately 30 minutes. Then, you may notice that it reduces the adhesive and makes it easier to scrape off by scraping it off or using a hard-bristled brush.
  • An excellent way to accelerate and simplify the scraping process is using a reciprocating saw that has an attachment for scrapers. If you use a scraper blade in a reciprocating saw, ensure it is positioned so that its bevel edge is facing upwards and the flat edge is facing down.
  • Suppose you are using hot solvents, water or a special glue remover. In that case, we recommend waiting a couple of minutes after applying the glue on the area before you begin scrubbing or scraping. This will allow the adhesive to soften, so take your time.
  • In contrast to the techniques of heating glue to enable it to be removed, one can also use dry frozen glue. The exposure of the glue to dry the ice can make it more brittle and, consequently, easier to remove by scraping it with a knife. This method should be used with caution. However, put the dry ice on baking sheets, then place the sheet on top of the subject area for a couple of minutes before scraping the glue.
  • When selecting a mastic glue remover, it is important to follow the instructions of the manufacturer to make sure the product is appropriate for the substrate you are working on. It is ideal for you to first test your glue removal in one area that is out of view to determine if it is effective before using it over the entire surface and damaging it.
