Edit: I meant plaster, not sheet rockLast couple of weeks my wall in my home started to bubble up and crack. I took off the outside layers of paint and noticed sheet rock chunks were easily falling out. My house is a brick house that was built back in the 50's and as far as I can tell no updates have been done since it was built. I'm nervous the water damage was from water coming through the mortar that appears to be separating. What steps should I take to fix this problem? Do I need to apply more mortar in places I can get to from the inside, then put more sheet rock over and call it a day?Here are some pictures I took: http://ift.tt/2vtddWM! via /r/DIY http://ift.tt/2ggkoPl
