Have a 25' x 5' section of concrete slab that I need to remove this adhesive from. I removed engineered wood flooring, and am going to lay LVP. Floor needs to be fairly smooth and level but I'm not worried about stains or imperfections. What (not expensive) chemical/soap/degreaser would most likely help loosen this to scrape up? It is VERY sticky as shown.

I had some black tarry adhesive left on my floor after removing awful vinyl tiles, and had to chip them off with a hammer and cold chisel. Took a while and left me with a dusty floor, so had to give it a coat of self-leveller.

We had the same, but on advice of our contractor had it tested for asbestos. Both the tile and mastic had asbestos and we had to hire a specialized company to remove all of it 🤦

I’d rent a flooring sander and go to town. Can’t be more than $100 for a day rental

Grinding would gum up and/or burn, and there's a lot to remove. Would have to rent a specialty scraping type machine. Would rather spend less and use some elbow grease.

Get a oscillating tool with a scraping blade onit, made for this.

You can rent or buy a floor scraper with a metal/carbide blade on it. It has a long handle like a shovel, with the flat blade on the end. It should suffice for taking that glue off the cement floor.

I have a floor scraper, but this stuff is just too thick and sticky. Can't get a blade under it unless it's razor sharp.

I’d try some less volatile chemical strippers. I have some orange ‘flavored’ stripper that seemed to work on the tar style adhesive. Get a little bottle to start, try a few methods (maybe cover with plastic wrap to lessen evaporation), before giving up on this method.

I think you can buy a long blade attachment for it.

You could skim coat it with modified thinset

You don't really care how well it adheres as it is just a shim

Try regular cooking oil on a test spot, leave it to soak for 24 hours. You can clean up the oil with blue Dawn.
