put a diamond blade in an angle grinder. You could do a masonry blade in your skill saw.

Re: Metal Lath Plaster (cutting)


will that cut both the plaster and the metal? will it be a good cut? He wants it replaced with 3/4" PT UL so i figure ill cut it about 3/4-1" larger and then put in a 1x4 chair rail to clean it up? This is the easy part of the job the best part is going down to the basement to take care of two termite eaten floor joists still not sure how Im gonna finagle the new one in there

If you strike a line and have a steady hand, you should get a nice clean cut. When cutting walls I used a grinder with a diamond blade it worked well. Like you said, cut it a liitle larger on each side then trim it and it will look first class.

True! I also take a good shop vac and hold the end of the hose right where the dust is coming off the wheel so that it sucks up most of the dust, dramatically reduces the amount you put airborne

Re: Metal Lath Plaster (cutting)


I found an even better solution when I went to do the job today. I took a hammer and hacked out the really messed up lower section which pretty much fell off, then i furred out the studs with 1x attached the plywood to the furred out studs and up over the plaster and then i cut dado in the bottom of the chair rail to fit over the plywood. All the customer wanted to know was how i was able to cut the plaster so fast without making a mess!!!!

Anytime I have to cut our plaster bead I use my plaster axe, just chop down and shears. I got a good size plaster and stucco job going now,

Sawzall on metal lathe plaster might work OK, but I don't recommend it for wood lathe plaster. You'll wind up breaking all the keys in the plaster and have a failed wall before too long.

Tuck point grinder with a vacuum works really well and is quick. We only cut the plaster with the grinder and break the wood out or cut with circular saw or a sharp chisel. Diamond wheels and wood = smoke and lots of it.
