The method for how to grout stone or ceramic wall tile is a little trickier than grouting tile floors. When you are grouting tile floors with a wider grout line than 1/4 inch it is easier to use a sanded grout, but when you're grouting tile walls for your stone or ceramic wall tile, gravity doesn't work with you the way it does for floors.
