hack of all trades
Ive been working on an apartment remodel in an old plaster and lath building. Running electrical, I'm having to fish emt through the walls, which sometimes requires cutting a 1" wide channel all the way down the wall, through the plaster and lath. This has been leaving those areas of the wall feeling less stable, being that some of the lath is not longer running tight stud to stud. I've been snapping plumb/level lines, carefully removing the plaster along them, and then cutting the lath with a circular saw to avoid the vibration of a sawzall. Does anyone have recommendations for ways to stabilize the plaster when I get around to patching up? It's tough with plaster because once it loses its original bond with the wood lath, you cant just pop a few screws through, you kind of need to replace it. Any tips?
