Can you skim over plasterboard with lime?
After a long search, I have found a specialist lime plasterer in my area.
He said all the things I expected a lime person to say.
My building has lime plaster in various states of decay. Much of it he is able to repair, which is a relief, as most builders said "hack off, bond/board and skim".
One ceiling will definitely be lost. Years of severe water damage have caused huge chunks to fall down, the lath nails have rusted and the laths fallen away from the joists. Part of the ceiling is intact because it has been overboarded and artexed.
The much of the beautiful coving and Georgian Adams style freeze has been lost, and what remains has been plastered over with some very hard plaster, maybe Artex, that won't come off. The CO is in agreement that the only thing to do is to remove it and replace with a similar pattern. Specialist decorative plaster people have advised the same.
I cannot go to the length of doing a new lath and plaster lime ceiling and the CO doesn't expect it. The main problem is that the room above will have to be worked on (plumbing, electrics, plastering etc and then inhabited as soon as possible. My understanding is that a new lathe and plaster ceiling needs to dry for months without the joists bouncing around in order for it not to crack. The £5000 cost is also a deterrent.
My options are:
Overboard the non boarded part of the ceiling. Not my preferred option because it could still collapse in one big piece.
Or skip the lot and do a new ceiling to current building regs.
The Lime man suggested skimming the plasterboard with lime
I had never heard that. Does that make sense?
