Just to show what I've been doing for the last couple of days, this is my rotten ceiling, to the left of a chimney breast.
Chimney stack removed and tiled over to stop leak.
Laths removed as they were totally rotten. Surprisingly the joists have survived. New laths cut and screwed into place using drywall screws. Painted with fungicide. I am now applying bonding plaster to the area to build it back up.
Those large penny washers you can see are doing two things: they are stopping the existing bonding plaster from de-laminating from the laths, and I've also injected Gripfill into the screw holes which bonds the existing plaster back onto the laths.
Someone is probably going to say either, "I'd pull the whole ceiling down" or "why not just use plasterboard?". Well, it was my decision. I did the same on a much larger scale for my entire living room ceiling which was beginning to fall down. It's now solid and looks great.
