I recently removed a ceramic tile floor from a cement slab downstairs,
which was not too difficult with a chisel and a hammer. I am left with
some of the residual thinset that has stuck to the cement. That's not
easy (or too speedy) to remove with a chisel and hammer, though it would
come with enough time.
Home Depot has a Floor Scraper (a rental), which I know are usually used
to scrape the floor coverings up. It's about the size of my Black and
Decker Electric Edge Trimmer, which I think is convenient for me. Would
the floor scraper work if I tried to use it just to scrape the thinset
off after the tiles have been removed? Nobody there could give me an
answer and I don't want to rent it and find that it doesn't work for
that, if it can be avoided. Does anyone have a better solution that
would be relatively quick?
