My mother's house is covered with these old plaster ceilings. They collect a lot of dust and have been slowly peeling away over the past couple of years, especially in the living room where we experienced water damage.
Recently she's begun renovations on the house and has finally moved to the ceilings. She'd like to all together remove the plaster ceiling in the living room and she'd also like to replace the ceiling in the kitchen with a tin ceiling.
The only problem is it's rather difficult to take the plaster off. We've tried peeling away at the parts that are already falling off but that only goes so far.
So any suggestions? She's been contemplating putting the tin over top of the plaster in the kitchen but I don't know if that's possible. Help?

Thanks a bunch
