Hi guys,
Total amateur DIYer here. Just pulled off the skirting and as the nails pull out they're taking half the wall with them! Behind the plaster is a black type of stone, which seems to be falling apart alarmingly easily. Just wondering if anyone knows what material this is and if we should be worried. Many thanks.
