I removed carpet to prepare for a 2 part apoxy flooring. I ran into a hugh amount of carpet glue. I tried a couple of products and go negative results. A friend of mine owns a concrete finishing company. He said go buy Bean-e-do. I used Bean-e-doo on 1,000 sq ft concrete basement floor. I used four gallons to remove carpet glue. This product is amazing. I put in on a section at a time and let it stand for four hours. I then used a sharp scraper and it came up. I shovled the remains up. Then I used a clay based cat litter to absorb to left over. Shoveled that up and then used simple green to clean and mopped the floor. We used the 2 part apoxy floor covering from Behr. Looks amazing. I paid locally $21.00 per gallon. It is worth its weight in gold. My rec room is kickin.
