Hello Guys, I've got a kitchen floor to tile which leads into a porch, but I have a problem with a small step (3 inches roughly) which seperates the rooms, do I tile to the edge of the step and leave it like that or do I tile the vertical part of the step. also when the floor is tiled the top of the step will have a rough edge where the tile has been cut, how would I tidy it up?
