I am doing some electrical renovation in the summer cottage and discovered that an interior wall is filled with a gray mass. The wall is about 20 cm deep.
Does anyone have any idea what it could be? Asbestos? The house is supposed to be built in 1913.
Looks like some kind of cement render. The house may be from 1913, but those masonite boards are much younger than that. Could it be that someone has smeared cement render on an old original kloasong wall with lime plaster?
