I am in the process of removing some wallpaper from a wall that we were planning to have re-skimmed. In doing so I have noticed that the plaster on part of it is bulging and cracked. I've been using solvite spray on wallpaper stripper which is basically just being absorbed into the blown plaster and it's all now coming away. What can I do to try and preserve as much of the plaster as possible or is this a lost cause? Presumably it's past the point of a re-skim at this stage.
A bit of background. Bought my first house 6 months ago. UK. Semi-detached. 1930s house. I picked the smallest room in the house to sort out. My plan was reasonably simple - remove paint from everything (including wood, walls and ceilings), replaster, repaint and recarpet (the latter three I was planning to outsource!)
However today I started peeling the artex ceiling off (asbestos free - we had it tested) and I started noticing these cracks in my curved ceiling. I assume they go all the way across the room, but I am a bit scared to pull it all away currently.
I have read that often these cracks are associated with the plasterboards above, which seems logical in my case. Is there anyone here who has more experience than I do of these cracks? If so, I was wondering :
1/. Are these cracks definitely due to the above plasterboard? Or do I need a structural engineer? 2/. What is the recommended way of dealing with them? 3/. Any other general advice?
