Need help ASAP sanded or unsanded for marble?
I need the great expertise of this group. I have a honed staggered marble mosaic backsplash, and have read that joints over 1/8 should be sanded, under that, you can go unsanded. My tile guy is telling me that he won't scratch the tile with sanded, and he's recommending sanded. He says it holds in place better and doesn't crack or shrink as much as unsanded.
I'm torn because I wanted the clean look of unsanded, but I am not the expert and I don't want him to leave and then find out in a month or two that he was right and the grout isn't as full and cracking.
My joints are about 1/16 in the smallest area, and then about 1/8 in the biggest areas.
He is saying that it will look more full to go sanded.
Your thoughts are appreciated!
He will be grouting tommorow.
