Sauternia - grout discoloration Perfect Marble 2 31 Mar 2014 11:46 EDT
Hey gang, just went to this prospects home and he has a problem with his grout. The owner installed the tile and grouted it as well.  He had another company come and flatten the floor and I think they did a great job. The only thin is the grout lines.  Some lines have darkened have u guys encountered this and what can be done about it
