First, I noticed that some people have title "moderator", what does that mean?
Second: I had planned on putting silicon on the corners as suggested (the tile job was so sloppy it requires something to hide the poor alignment of the tiles in the corners of the walls), but I was unsure whether I should grout first. I just want to make sure I understand correctly... skip the grout and only do silicon.. right?
Also, since the tile job was pretty sloppy, there are some pretty big gaps where the walls meet in the corners. Would that make a difference... would it be better to fill the entire gap with silicon or should I fill in with grout and then top it with silicon?
