I had to lift up two loose tiles on a bathroom floor. The tiles were
installed about 3 years ago by a professional over a new plywood subfloor
with a gray colored adhesive - or cement. I was able to remove the tiles
easily without damage and need to reattach after drying the wood floor -
some water got underthe tile. I have some extra tile but would not rather
bother to rent a tile cutter etc unless really needed so I thought I could
chip or scrape carefully to get some off. The tiles only have about one
third of the surface wiht the cement.

Is there chemical that would help (phosphoric acid tile cleaner?) or do I
just need to scrape? Do I need to get most of it off or just enough to be
able to re cement it down and not have a high tile.

thanks

I've had good luck with a wire brush in an angle grinder, or mounted
to a stationary grinder. Makes a mess, but cleans off the adhesive,
whether it is mastic or thinset (probably mastic if it was installed
over plywood (not a good idea, especially in a bathroom).

Wear eye protection.
