I’ve just removed 40 year old tiles from the basement floor and would like to remove all traces of the tile before I paint the floor. The surface is now smooth and the scrapper does not scrape off any of the residual glue which is firmly “stuck’ to the floor.
Is there a chemical that could dissolve the residual old glue, or make it easy to remove? Should I contemplate sanding/scrapping the floor to remove the black tar like substance which is hard?
Or simply paint of the floor with a proper basement floor paint. (basement floor does have radiant heating from the 1950s.)
