I am in the process of redecorating my house and wondered if you could advise on the following issue I have. All ceilings, top and bottom appear to be made from a board - it looks like whitish grey plaster sandwiched between two pieces of course paper (brown/grey). Then a thin skim of grey plaster has been put on to hide the sheets and nails. The house is a 1955 ish house, and ceilings are original.
I had a small asbestos insulting board removed that was behind a gas fire, but wondered if this could be a form of asbestos board or asbestos cement board - the board is light, powdery and close up has small bubbles in it.
Your thoughts would be great. Thanks
