Can you identify this ceiling material
Hello everyone,
Not sure what ceiling material this is in my garage (old 1920's row home in Philadelphia), but I want to take this down so I can insulate, then install sheetrock.
My question is, can you tell what this is? I don't want to run into any problems removing it (hoping it's not a material requiring abatement like asbestos).
I thought it could be plaster or some type of concrete or mortar because there are metal rails that makes up this ceiling.
Thanks.

That looks like plaster over lath. I have no idea of the composition of the plaster though.
Another reader may have an idea.

The metal rails you are referring to are actually part of the lath known as " expanded lath". The cement material, judging by the way it is decaying near the water or heat pipes , is probably gypsum plaster basecoat mixed with sand aggregate. It may, considering this is a garage, contain asbestos. A test is relatively cheap.
