I am planning a 160sqft installaltion of Honed Travertince over Slab (previously existed carpet), with 1/8" grout lines. Is it neccessary to seal the concrete before? Also I have been told various thinset/mud approaches for the installation. Wanted to hear any suggestions for the preferred method.
I am hoping that a reinforced thinset applied with a 1/2" notched trowel will be sufficient.
There is also various comments about sealing the tiles prior to installing ( I am assuming to make cleanup easier)
