My new marble hexagon's look horrible- please help
I just had a beautiful polished crema Marfil hexagon floor installed. It look absolutely gorgeous until it was grouted. There was a haze all over the floor after it dried. The tile contractor has been back twice and today used a buffer to try to remove the haze. It still looks dull and nothing like it looked before it was grouted. He insisted it is fine and that is how it is supposed to look. I did some research and I realized he used a sanded grout. The grout spaces are a little less than 1/8". Any help or advice on what to do now? Can it be fixed, did the grout cause the problem? It was also not sealed before it was grouted. Could that have caused this? I am at a loss and do not know what to do. Any help or information would be greatly appreciated.
