They will probably do a good job on the outlets. They make abrasive blades for jig saws and sawsalls. I suppose the bits are carbide of some kind. it will jar the rest of the wall or ceiling less.Ī RotoZip tool with a plaster cutting bit will do the best job on the outlets. Screw the nailer to the joist or stud rather than nailing it. You are right about cutting the lath and plaster flush to the joist or stud and adding a nailer. It easier to fill the drywall to make a flat patch than to feather our onto the painted plaster. Leave the drywall just a little bit shy of flush. I can actually do it with plaster faster than I can with drywall and it fits perfectly when finished but that's just me.

I've been researching the button board & plaster ceilings/walls that are in my 1949 house and have new respect for the quality of the materials. You seem to think that somehow this is inferior to more modern (read cheaper, thinner, less soundproof, softer) drywall. ![]() Is the wire mesh everywhere or only in angles and above and below the corners of doors and windows? It's messy but to cut holes use an abrasive circular blade which will cut through the plaster, the lath and the mesh and leave a nice smooth edge.įor hanging pictures use a masonry bit to drill the hole and wall anchors just like for drywall unless you hit a stud. I don't know why you are troubled by the mesh. Or do you have metal lath? Which is mesh of about 3/8" X 1/2" and formed of expanded metal? Is the mesh woven wire of about 20 gauge with 1" mesh (rarely 17ga 1 1/2" mesh)? it is also called RockLath but that is a brand or button board because of the buttons formed when the plaster was pushed through the holes. The plaster is probably about 3/8" -1/2" thick. The lath is gypsum lath It is 3/8" thick and the sheets are 48" X 16". it's too bad this kind of quality is not typical now adays. ![]() You are very fortunate to live in a superior house. ![]()
