Can't understand why the original builder sealed the floor first and tried to clean second?? Very Strange. I have never refurbed a concrete floor, but I would think that the way forward would be diamonds?? Build up to a finish that the client is happy with. Am I barking up the wrong tree with this? I would be interested to know the outcome, however, we are still using stone for floors in Yorkshire, not many of us are brave enough to change to concrete....yet!
