I've got a flag stone floor downstairs in the hallway. It's rough stone -
none of your fancy cut stones. The kind of thing you'd find lining the path
in your local church yard!

I've lived in the house for four years and have totally neglected them. The
previous owners appear to have polished (sealed?) them with something which
is now flaking off. Whatever they used, it turned the stones from their
natural grey to a kind of yellowy-gray.

I just want to have them looking top notch. I've already gone through and
cleaned off various spots of paint, and so on. But what should I do next?
Are there are particular products?

Sounds like an acrylic floor polish. Unlikely to be a true sealer, they
aren't easily obtained by Joe Public. Flaking and yellowing are typical
symptoms.

Look in Yellow Pages under Janitorial Supplies to find a local supplier and
ask for Floor Polish Stripper. Extra cost but well worth it is a 'No Scrub'
or 'Speed Stripper' which will save a lot of elbow grease. You will
probably have to buy 5 litres.
