I am a newbie to this site. I need some advice with some repair I am doing in my living room. I have an interior wall which meets an exterior wall at a 135 deg angle and has a corner bead. Last winter I notice a gap openning up at the corner. I hired a painter to come fix it and it looked great but this spring the whole corner bead has pulled away and out from the wall (I'll try and post a picture). Question I have is should I rip out the corner bead and use caulking (just thinking it might be more flexible and allow form more expansion/contraction) or is there a better way to do this? Thanks for any help you can give.
