    The tile have been removed, but some of the glue (put down in the early 70's) is still on the concrete. It is very smooth. Can ceramic tile be installed over this or does the glue have to be removed?

    Maybe try sanding it? It probably should be fine if you take a level to it and make sure it is not above the concrete surface more than 1/16 in.

    How do I remove carpet glue from concrete?
    Community Answer
    Mix 1 cup of trisodium phosphate (TSP) in 1 gallon of hot water. Spread the solution over the concrete area with carpet glue. Let it soak for 20 to 30 minutes. Then, use a razor blade scraper to remove the adhesive. If the area is too large to be tackled with a manual scraper, you can buy a heavy duty glue removal machine.

    How do I remove leftover glue that is on a concrete floor after removing the vinyl flooring?

    The best way is to buy a long handle scraper, and go to work on the glue to life it up. Yes, it's hard work but it gets almost all of the old glue off the concrete.
