slate floor resealing

Question:
I bought a house with slate flooring, It really looks good, but I have a problem. The slate is a blueish gray but is turning yellowish geen. I want to remove the yellow, but don't know how. I had someone look at it a few years ago, and he tried a few different removers on it, and he found one that worked. He wanted $1,500.00 dollars to remove it and reseal it, but told me to wait until the weather got a little cooler. Well Hurricane Katrina came, and I never got it done. I have no way of getting in touch of him, and he would not let me know what kind of remover he used that worked. I have called many floor people in the area, and they have no idea how to remove it. I am hoping you could help, the floor is beautiful underneath the yellow. If you could help let me know.

it does give reasons why this may have occurred, my advice to you would be to call Fred or an advisor at NTC-STONE.COM, they will give you the answer to this question & they will advise you of different remedies to try first & it wont cost you $1500 either.
