Can I use sanded grout on porcelain tile?
Also to know is, what kind of grout do you use for porcelain tile?
Moreover, can you use sanded grout on polished porcelain tile?
Sanded grout is normally recommended when the grout seams are 1/8 inch wide or more, as the sand provides extra bonding power that prevents cracking. Some care is required if using sanded grouts on highly polished tiles, as the sand can actually scratch the surfaces. Testing the grout on sample tile is a good idea.
The short answer is no, you should not. Although grout does not add to the stability of the tile installation (unless it is epoxy grout), you still need to grout it.
