RE: granite flooring with flexbond thinset
I bought 18x18 granite (Venitian gold) for my entry way. My installer said he could install without any grout in between. He is using "Flexbond thin-set mortar". The granite color had changed as soon as he laid the tiles. The golden color in my granite turned to green (like the thin set color). My installer says it is natural for the porus granite to change color upon installation. Is this right? I am not happy with my golden color granite turning green. Any help/uggestions are appreciated.
If the Flexbond has been absorbed by unsealed tile, I'm afraid there's not much that can be done.
