Hey, first time user here. I'm getting ready to start some basic renovations to a room in my house, and I've run into an issue with three small pieces of decorative corner molding. These are approx. 6" long segments that were situated at the corners of my plaster walls, at the point where the wall meets the baseboard (hopefully the attached pictures uploaded correctly). Of course, over time the nail anchors loosened in the plaster, and not only have these corner molding pieces fallen off of the wall, but they've taken chunks of plaster with them. Now, I'm trying to figure out how (if it's even possible) to re-attach these corner molding pieces. I want to do this right, so they won't just loosen and fall out again after six months. Any helpful advice is appreciated!
