Just trying to figure out if this is asbestos?
Any help appreciated.
What you are looking at is fibrous plaster, true gypsum, it is cast on horizontal beds with fibers included to give strength. I has no Asbestos in it. Houses before 1985…
That brown colour looks like Masonite or hardboard. Get it checked but typically asbestos was used in wet areas and plaster board or Masonite in other areas
