I'm installing 12 x 24 polished porcelain tile (home Depot Model # NHDCARR1224P) with 1/8-3/16 gap. I am wondering whether to use sanded or unsanded tile. I am aware that for gaps 1/8 or less, unsanded is recommended. Anything wider it should be sanded. Not having installed polished tile before, my concern is more on the fact that this is polished and whether sanded grout will scratch the surface as I am applying the grout. Any thoughts on this? Thanks.

[left]hey guys I’m new to the site. We are renovating a home now and are having flooring trouble. The existing brick flooring will not come up in kitchen,living, dining. We have even had 3 crews come out to try with all sorts of implements. We have decided that raising the bedrooms floors by about 1/2 inch is the only solution without having a drop down into the rooms. What’s the best method to raise the bedrooms? Self leveled, some other cement/concrete, or can we use more mortar with a deeper trowel? Please disregard any ignorance on this newbie’s part! Thanks![/left]
