You should never use a sawzall or any type of back and forth saw on Lath and plaster.


It moves the lath back and forth and destroys the plaster key on the lath and the wall can be ruined .


The only saw you should use is a circular saw.


The binder in the plaster is Horse hair and the preservative in the hair is arsenic

Sorry I posted new topic and did not think it would end up there.
I stated it when some one said do not give a sawzall to a
plumber and it reminded me about how a sawzall ruins lath and plaster.
But that is not a bad place for it as most lath and plaster was
used in the time of Knob and Tube . .
Taking out Knob and Tube can ruin a wall very easily

Well, it can be here. It’s also tough to cut blind with a sawzall because you can’t set the depth, therefore you may cut into electric wires. icon_eek.gif

So who cares if you are removing the Knob and Tube that the wire is cut.
I would hope the first thing you do is shut down the Knob and tube circuit.
Again you should not be using a Sawzall in Lath and plaster .
A skill type saw with rotating blade is easy to set the depth and does not break the lath away from the plaster as bad.

I have never heard of it being a big concern .
I am not the least bit concerned .
I believe it was used in very small amounts strictly as a persuasive .
It seems to have worked it has been there since before I was born.
