Mastic, for example, tends to come off with a little hot water and some light scraping. However, if you need to remove stronger adhesives from concrete such as flooring adhesive, vinyl adhesive or laminate glue, a stronger solvent like acetone, paint stripper or mineral spirits may be required.
Klean-Strip Green Floor Adhesive Remover removes adhesives from wood, concrete, metal and masonry. It's easy to use because it stays wet and active for up to 24 hours. Low odor and less harsh on skin.
Apply a small amount of acetone or white spirit to the concrete surface, and check that it's compatible. Apply the solvent to the glue stain. Use a cloth soaked in solvent to remove the glue. Clean up.
Acetone: Acetone is a common solvent that can soften some types of adhesives, including some epoxy formulations. Soak a cloth in acetone and apply it to the glued area. Let it sit for a while before attempting to scrape the glue off.
To do this, heat the adhesive with an electric heat gun or blow dryer. Alternatively, you could coat the adhesive with petroleum jelly or mineral spirits for at least 12 hours to a day. Be aware that mineral spirits are not recommended for tub surrounds, vinyl, plastic, painted surfaces, or varnish.
Read the adhesive manufacturer's instructions to check whether acetone or mineral spirits is best to get the glue off the concrete. Apply a small amount of acetone or mineral spirits to a rag and briefly soak the affected area. Wipe it off.
Apply Heat. If you are dealing with a delicate surface and are unable to use adhesive remover, acetone, rubbing alcohol, etc., a bit of heat may do the trick, without damaging the surface. Some stubborn adhesives melt or soften and become much easier to remove when heated. Heat the adhesive using a heat gun.
If gentler methods don't work, try more powerful chemical solvents, such as lighter fluid, paint thinner, acetone, or rubbing alcohol.
Use a cotton ball soaked in pure acetone or nail varnish remover, and press it against the glue. Once it's dissolved, it should be easy to wipe away. Alternatively, try scraping away the glue. Use a putty knife or razor blade.
For stubborn floor adhesive, apply hot water to the mess, wait for several minutes, then apply Goo Gone. Before continuing your renovation, make sure the surface is completely dry prior to applying more floor adhesive.

Have you ever had to remove carpet glue from a concrete floor? If so, you know it's not an easy task. You could try to scrape it off with a putty knife or with a wire brush, but that can be very time-consuming and tedious. Instead, you can use muriatic acid to remove the glue quickly and effectively.
Masonry adhesive creates a very strong bond between masonry materials, and it's usually used for projects that require a long-lasting bond — like attaching stone veneer or architectural accents. Mortar, meanwhile, creates a slightly weaker bond than masonry adhesive but is still strong enough for most projects.
For mastic, you'll need to use a solvent-based remover to remove the adhesive thoroughly. On the other hand, acrylic-based adhesives require water-based removers. And in the case of polyurethane-based glue, you'll need urethane-specific removers.
If the adhesive is too hard to scrape, apply a light layer of baby oil or petroleum jelly, wait a couple hours, then scrape.
A: Goof Off is industrial strength; it is the super solvent, BUT, is so strong it will dissolve a great number of plastic items. Most clear, polished plastic services will become frosted from just a damp wiping with Goof off. Where Goo Gone is more of an oily solvent.
To remove strong adhesive left by a sticker, apply an oil-based substance like cooking oil or WD-40 directly onto the adhesive. Let it sit for a few minutes to loosen the glue, then gently scrape it off with a plastic scraper or credit card. Wipe clean with a damp cloth.
White vinegar is a safe and natural cleaner, deodorizer, and adhesive remover you can use on many surfaces. Soak a paper towel in vinegar and cover the sticky spot. Let the vinegar soak for a few minutes to dissolve the adhesive, then scrape it off with a credit card.
