John, I covered an old painted brick fireplace with flagstone about four
years ago. When finished I painted it with water based poly. Has stood up
well, looks great and did darken the stone to a very nice patina.
I have a large sun room extending from the front of my home. The sun
room has a flagstone floor with large stones. We'd like to finish
this floor so that it has deeper color and some sheen to it. I have
seen stone floors that appear to have been finished with a thick coat
of polyurethane? Is this common and is it as simple as it seems? I
have used some stone-specific polishes, etc. on this floor and they
just don't give me the finish I want.
Informative help appreciated...
