Hi I hope someone can help me on this. I have a house that has un-gauged Lime stone on the floors, It looks like that the stone was quarried then split to make tile and never honed. The surface looks like the texture of slate, very un even with very high ares and very low areas and the lady now hates her floor. I tried metal bond diamonds and the seem almost to stick to the floor. I tried a floor edger with 36 gritt paper trying to Knock down some sharp edges and that hardly touched the stone. My question is has any one tried to flatten a floor like this and what did you use?
