How do I restore my flagstone flooring?
I have just moved into a 1852 built Victorian house. We have just discovered that in the kitchen and the small hallway that it has original flagstone flooring. Someone in the past has (stupidly) limmered (if that's the word) over it. It's like black smooth tar. I accidentally split a bottle of turpentine over the floor and it dissolved a very little hole in the tar. (That's how I had knowledge it was flagstone underneath). I'd love to restore it back to flagstone. How do I do this? I know turpentine did it a bit but that would be really messy and expensive because it is a big room. How do I get rid of the tar and then what do I need to do after that anyway? I head somewhere that you need to pull all the flagstones up, and lay plastic underneath and level it out with sand and re-lay them. All ideas will be much appreciated thanks. 🙂
