After quite a few tests of the grout in the kitchen, we went with an Antique White Non-Sanded Grout. Gino grouted all of the seams and little cracks yesterday…and this morning I am sponging the entire floor tile by tile. I am using two buckets of water and one sponge to clean the thin film of grout from the tile surface…one dirty water bucket that I use to dip the sponge into after wiping one tile and then the smaller bucket to dampen the sponge in clean water so I can get started on the next tile with some relatively clean water (I breaded chicken in a similar fashion when I was a line cook….clean hand…dirty hand).

Here are some pictures after one round of sponging. It will probably take three meticulous passes with the sponge to get the grout residue off of the marble before we are able to seal it with the 511 Impregnator. It took me about 40 minutes to go tile by tile…and my back is feeling real nice. It really makes me appreciate the hard work Gino has put in to get the floor completely flat and the butt joints to line up so well.
