Bob,
This is a question and not an answer. Way back when I worked for the telephone companies they had a big floor did with some kind of an aggegate/overlay I think it was and it had all kinds of sparkley stuff mixed in and turned out really beautiful. But I keep thinking that stuff was hot when they put it in. I do remember that they used something and took the top 1/8th inch off the floor to make sure there were no contaminants and then vacuumed it to get rid of any dust or loose stuff. This was in a big building where we had some of the computers and I could never understand why they did that in an area where the only traffic was people walking. But one of the contractors said they used that stuff in commercial garages and it would stand up to almost anything. Is this really so? As I said, it was many years ago and I just happened to be in that building at the time and watched some of it because I had never seen a floor did like that before. I haven't seen another floor like that one since either.
