Carpet adhesives are formulated to put up with years of scuffing, trampling, and footfalls. When ripping up your old carpets to lay down new flooring, you may be disappointed to find residual carpet glue clinging to your subfloor. These adhesives seldom fail, but it is for this reason that carpet glue can be extremely difficult to remove from a concrete subfloor. This article shares the most effective methods for removing carpet glue from concrete safely.<\/p>\n

\"How<\/p>\n\n

 <\/p>\n

 <\/p>\n

What Is Carpet Glue?<\/h2>\n

Gluing a carpet down is an ideal, long-term option for wall-to-wall carpeting. Some carpeting comes with adhesive backing and others require you to apply the glue between the subfloor and carpet. The latter is usually spread with a trowel or similar tool and comes in a variety of different types. In recent times, we have seen the rise of eco-friendly carpet adhesives, which usually come with an acrylic or synthetic rubber base.<\/p>\n

It is important to note that if your carpet was installed before the 1980s, there is a good chance that the adhesive may contain asbestos. Asbestos is carcinogenic, thus extreme care needs to be taken when removing it. This is why you should call a professional if you are unsure of the nature of the glue beneath your carpet.<\/strong><\/span><\/p><\/blockquote>\n

Methods of Removal<\/h2>\n

There are a number of methods for removing carpet glue from concrete. The following methods are presented from the most DIY-friendly to the least accessible and most difficult. Some of the methods require just a bit of elbow grease where others require the use of harsh chemicals. It is advised that you try the first method and then move on to the subsequent methods only if necessary. By doing this, you can avoid spending money needlessly and avoid exposing yourself to toxic chemicals.<\/p>\n

\"How<\/p>\n

 <\/p>\n

Scraping<\/h3>\n

A quality scraping tool can go a long way in removing carpet glue from concrete. A paint scraper is ideal, although a five-in-one tool or a spackling knife will work just as well. A long-handled floor scraper will keep you off the ground, but if you do not have one, it is advised that you use knee pads as a few hours of scraping with a short-handled scraper can be torture on the joints.<\/p>\n

A pair of quality work gloves will prevent blisters and increase your grip on the scraper. Use a broom to sweep away the dried bits of glue before moving onto the next method.\u00a0You may be able to remove all the glue with a scraper, but this will depend largely on the condition of the concrete and the strength of the glue. More porous concrete may require you to use hot water or solvents.<\/p>\n

\"Removing<\/p>\n

If the glue is proving to be stubborn, use this scraping technique in conjunction with the following method.<\/strong><\/span><\/p><\/blockquote>\n

 <\/p>\n

Boiling Water<\/h3>\n

If the glue is very old, it may have started to break down and loosen its grip on the surface of the concrete. You can further persuade it with a bit of hot water. Boiling a small pot of water on the stove and pouring it onto the affected areas can help lift the glue from the surface of the concrete.<\/p>\n

It is important to take care when pouring hot water onto the concrete. To avoid excessive splashback, pour the water from a short distance as opposed to a dizzying height. It is also advised that you wear a pair of rubber gloves and rain boots. This will protect you from the scalding splashback.<\/p>\n

For the best results, lay a towel over the glued area of concrete and pour the hot water onto the towel, letting it sit for two to three minutes. The towel will retain some of the heat, thus increasing the efficacy of this method. Lift the towel and remove it from the area, after which you can begin removing the glue with your scraper.<\/p>\n

Whether or not you are using a towel, it is advised that you work on one small area at a time rather than pouring hot water over the entire floor. If you opt for the latter, you will more than likely find that by the time you get to the other end of the floor with your scraper, the water would have cooled down and will not be effective anymore.<\/p>\n

 <\/p>\n

Ironing<\/h3>\n

An alternative to using boiling water is to use an iron. The rule of thumb here is that warm glue is easier to remove than cold glue. Lay a single sheet of newspaper down on the affected area of concrete and then run the hot iron over the newspaper until it is hot to the touch. Remove the newspaper and begin scraping before the glue has a chance to cool down.<\/p>\n

You may have to repeat this procedure multiple times, especially when dealing with a large area of concrete. Needless to say, always be careful when using a hot iron as it can burn your skin.<\/strong><\/span><\/p><\/blockquote>\n

A heat gun is an alternative that can also be effective in softening the glue to make it easier to remove. Heat the glue directly with the heat gun until it softens, and then scrape the glue to remove it. Address one small area at a time to avoid the glue cooling down and returning to its stubborn state.<\/p>\n

 <\/p>\n

Ammonia and Detergent<\/h3>\n

Ammonia is an extremely strong chemical that can be effective in removing glue from concrete, but it should be diluted with water first. Mix two cups of ammonia and a few generous squirts of dishwashing detergent into a bucket of warm water. It is important to wear goggles, rubber gloves, and a respirator when dealing with ammonia, as it can give off toxic fumes.<\/p>\n

Use a coarse bristle brush to scrub the area of concrete to remove the residual glue. The ammonia and soap solution will soften the glue and allow it to lift from the concrete. Wipe the concrete with a cloth and continue applying the solution and scrubbing until all the glue is removed. It is advised that you rinse the concrete with a mop and fresh water after the glue has been removed.<\/p>\n

\"Removing<\/p>\n

 <\/p>\n

Acetone<\/h3>\n

If you have tried the above methods and are still having trouble, you may have to bring out the big guns. Acetone is advised to begin with, but solvents such as paint thinner and turpentine can also be very effective when trying to remove carpet glue from concrete. Acetone is flammable and can give off toxic vapors, so be sure to wear a respirator to avoid breathing in any noxious fumes. You should also wear safety goggles and put on some gloves to prevent the solvent from drying out your hands.<\/p>\n

For this method, a coarse bristle brush will work better than a scraper. Pour a quarter of a cup of acetone into a tray to make it easy to work with. Dip the brush into the solvent and begin to scrub the concrete. The acetone should melt the residual glue and, in doing so, lift it from the concrete. The brush will help work the glue off of the surface. Use a clean cloth to wipe the surface and repeat if necessary. If you are dealing with a very small area, you can use an old toothbrush instead of a scrubbing brush.<\/p>\n

 <\/p>\n

Sanding<\/h3>\n

If you are dealing with extremely stubborn glue or glue stains, you may be tempted to try a more abrasive technique. One option is to hire an industrial floor sander, which is ideal if you want to avoid hiring a professional. The cheapest DIY option is to use an angle coupled with a diamond cup wheel.<\/p>\n

Whichever machine you choose, be aware that it is not as DIY-friendly as the aforementioned methods. However, for someone with a bit of experience, using a floor sander or angle grinder should be fairly easy.<\/strong><\/span><\/p><\/blockquote>\n

When attempting to sand or grind glue from concrete<\/strong><\/a>, it is advised that you wear the appropriate safety gear such as goggles, gloves, and a dust mask or respirator. Full-coverage clothing is also advised. When sanding, be careful not to focus too much on one area of concrete, as this can create an uneven surface that may require you to cough up money for repairs. Move over the surface of the concrete lightly at first, and increase the pressure as needed.<\/p>\n
