I need some advice about polishing tiles.  A client ordered the tiles honed but was now thinking they wanted it polished.  The tile company gave me 2 tiles to test that were similar, one polished up after 1 step, the other after 3.  The question I have is that if they accept our bid, they want the 1900 sf of 16” tiles to be polished before they are installed.  Do I have to do these 1 at a time to prevent any breaking, or is there a way to lay them out and do it that way?
