 Just finished removing 400 sq ft of ceramic tile and carpet tiles. Ground off the thinset and glue and sealed with a water based polyurethane. looks good. Now I have a 200 ft section where there were carpet tiles, but they were removed quite some time ago and the exposed glue has dried out and is very thick...1/8th of an inch. Impossible to grind this stuff as it just smears with the heat  of grinding. Tried my floor scraper and I'll be 90 before getting anywhere with that. Anybody use a stripper for such glue? It is called a release adhesive. This is in Home depot. I am working at night but concerned about any fumes of course. Any ideas would be helpful.

I recommend you use an

I recommend you use an electric plug in machine that is heavily weighted (some refer to them as tile removers; but they also remove thick/hard glue as you are describing).  They have a blade that is about 8" wide.  You will have to experiment as to the best angle to set the blade at for rapid efficientcy.  The blade will become dull as you use it; therefore, have a bench grinder or belt sander with course sandpaper handy for sharpening on the job site.  After you get it down to wher you start seeing concrete itself ghosting through (ie: what is left being only a few mils) then use a floor grinder to remove the rest.  This type of equipment sort of shears/cuts it off the conrete; whereas as you have experience revolving grinders and the heat generated from friction tend to just gum everything up and are the best pathway to take as to removal.

There are various strippers that will work, but most have fumes, all are messy and time consuming as well as clean up/off afterward.  Home Depot stocks BEHR Flooring Adhesive Remover (I have not used it, but I know of those that have and claim it works fairly well to get the bulk of it up after it has softened up and a manual floor scraper can be used; if the glue/mastic is really thick you might need to repeat the process; of course you still have to scrub the floor, sometimes first going over with a floor sander/fine screen or grinder.

Thanks for the advice. I

Thanks for the advice. I found a 5 gallon pail of orange gel degreaser that I bought years ago in the back of my shop/ It is made by ZEP. I treated the glue with that and I was able to come home early! That gel emulsified the glue and it wiped off with a cloth. Took 10 minutes!!!! Let it dry and then ground the area and sealed it with a WB polyurethane. Looks great. First time that I have used a stripping agent on glue as compared to grinding it off. Cleaner and faster in this case.

Yes.. according to the data

Yes.. according to the data sheet it effectively emulsifies tar and asphalt, industrial glues and protective coatings and for removing scuff and rubber tire marks.... how many of us get asked to do that? I will see now what protective coatings it will work on also.

Wow ...that's amazing.... I

Wow ...that's amazing.... I am IMPRESSED at how well this worked, especially being classified as a a cleaner (not a chemical stripper, many of which contain solvents) you didn't have any of the odor issues either I assume. 

Thank you for sharing  ... verbally and with a photo image attesting to ease.  I sure a great many DCF members/contractors will fee this is VALUABLE information.

I have found that the strippers, even when "green", have a negative stigma attached.

Much boliged for the share

My brother-in-law is an expert in flooring and will surely pass on this info to him. We too had carpet tiles at my home, when I was young. Cleaning it was a little bit tough, but always loved the feel of carpets. I read on a website that flooring maintenance is very important and hope to learn some more in these forums. Great work.
