I recently bought a brick building from 1938, which is a former store.
When I removed drywall in several places, in front of partition and divider walls, as well as a bricked-up window, I found a thick black paint that was painted on about 2 cm thick plaster, beneath which is the brick. In my eyes, the black paint most closely resembles bitumen paint.
But why would someone paint a plastered brick wall indoors with that? What else could this type of thick black paint be? Has anyone encountered something similar?
(I believe the paint must have been added later than when the house was built because it was also on the bricked-up window)
(It does not contain asbestos because I sent a sample for analysis)
