If anyone planing to have matt homogenous tile for floor, get ur contractor to check whether is all the
tile having the same thickness. As I don't like shining surface , I choose matt surface homogenous tile and is lucky my contractor checked and found that the floor won't be level when put together.He ask the supplier and they said the shipment is like that for matt surface.And even lay it apart like ceramic tile, the edges is not smooth.So I have to reselect and get ceramic tile instead. But to and fo, I lost one week.But still lucky hav'nt lay yet.
