How To Remove Glue From Concrete Slab?

Hello,

I am trying to determine the best (easiest) method to remove hardwood glue from a concrete slab. If you look at the attached pictures, you can see that I have removed the previous hardwood flooring that was installed 15 years ago, but now I need to remove the leftover glue.

I have attempted to remove with a hammer drill, but it is very labor intensive and taking forever. I think I have heard there is some kind of liquid you can pour over the glue and it will soften / dissolve it and then you can remove with a surface scraper or putty knife.

Any help or suggestions are greatly appreciated.

Thanks in advance!

I find using a broad, flat chisel blade in a rotary hammer set to hammer only works pretty well.

They also grind/sand it off, a PITA!

What are you installing in place?

Hello, thank you for all of the replies to my message.... I needed to remove the glue from the slab so that I could have luxury vinyl planking installed (LVP). Apparently I didn't need to remove this, but I wanted a smooth surface anyway.

After testing 4 different products from Home Depot (Goo Gone, Krud Kutter, Klean Strip, and CitriStrip), the hands down winner was CitriStrip! After applying this to the leftover glue and letting sit for a couple of hours, it came off very easy with a floor scraper.
