Hi.
Concerned amateur here, about to embark on needing to make good a hole in the ceiling... It appears to be plaster board over what I assume is lath and plaster. But the plaster has large black particles within it (pictures attached). What can this be? Is it usual to have aggregate in this layer of plaster? Could it be something more concerning, such as asbestos vermiculite suspended within it/is this a possibility?
Thanks in advance for you help.
