Question

What is the best method to completely remove old multi-purpose floor covering adhesive from concrete? There was carpet glued to the floor, and when removed the glue remains. New tile is to be installed so the glue needs to be completely removed.


Answer

On concrete, there is less concern about scraping or scratching the floor than with tile or wood, so I would try one suggestion Iíve read about and that is to use a sturdy hand held scraper after softening the adhesive with boiling water.
Pour the boiling water onto a small area, wait a few minutes for it to work, and then use the long handled scraper.
Other approaches would include the the use of a commerical adhesiver remover or a wire brush or scraper attachment for a standard rotary floor machine.
Keep in mind that there are numerous types of adhesive and yours may not respond to this method. You may have to rent an electric powered floor scraper (not sander) to work a large area successfully.
