Hi. I need to replace a section of ceiling plaster damaged by a leak. Before I cut it out just wanted to check it's safe (i.e. no asbestos). Pics attached, hope they're clear enough. Doesn't really look fibrous but darker in colour than other plasterboard materials I've come across and not sure what it is. Any help gratefully received, thanks.
Pretty sure I’ve come across old plasterboard that’s grey inside. Can’t see what else it could be as it’s got the paper backing and is skimmed
