dumb question.. I am going to use the same tile for my tub / shower in the basement as I want to use on part of the wall in the bathroom. Can you use the same mortar over sheetrock that you do for the wonderboard?
I was originally going to use green sheetrock to tile over in the shower then learned that while it is "code approved" I tore it out and put in wonderboard (or durarock stuff) after I had people warn me about mold.. but I want to take the tile from the shower and wrap it around an adjacent small wall and wondered if the same mortar can be used or if something different is needed to get the tile to mount to sheetrock......??
I did a tile backsplash at our old house and it was the same, the only difference was the size of the notches in the trowel you're supposed to use. Not sure about your case, but when I was doing it, it was much easier to put the mortar on the tile and then put it up rather than buttering the whole wall the way you usually do it on a floor.
