Is backer board essential behind tile backsplash?
We're redoing our galley kitchen, and one installer says we must have backerboard and another says we don't. The walls already have sheetrock on them, although they're messy from removing the formica.
The second problem involves finishing the ends of the tile. There are no bullnose pieces or rods(?) that match our mosaic to put at the end of the run or between the uppers and the window sill. With backerboard, they say we'll have a half inch "glob" of grout to finish it off. Without the backerboard, it'll only be the width of the mosaic. What is the best way to have a finished look. I don't want to stare at a huge glob of grout everytime I'm at the sink.
