I need to move some pictures around, which will expose the holes from the anchors and screws. I would like to patch and paint them. The holes are fairly small, although the plaster has crumbled a little around a few of them. So . . . what's the best way to do it? These walls were put up in 1933, but are in really good shape. I'd like to keep them that way! 1) What is the best method for removing the plastic anchors from the walls? 2) What, if any, prepping is needed before patching? 3) What's the best patching compound to use for plaster? Patching plaster or spackling compound? I've read that both will do. Many thanks . . .
