The house was probably built in about 1900 (so Edwardian) and I would guess much of the plaster work is still original. We refurbished the house 3 years ago and suffered from lots of plaster falling off when we took the wall paper off, including an entire ceiling dropping out in one room. I am therefore concerned about hacking too much away, as the result could be disastrous as we also still have some original plaster features nearby.
I am looking to replace the ceiling lights in the hall with two chandeliers: the heavier one weighs about 3 kg, so nothing too grand.
So have taken the old light rose down and of course lost a circular chunk of ceiling that has exposed no joists, but lath. I have no idea how far the joists are, and no way to get at them from above as we have a floating floor sitting on top of the floor.
So two questions:
Will the ceiling be able to support the worst case scenario of 3 kg?
Assuming that I have repaired the plaster work and screw into the lath?
How the hell do I repair the ceiling?
I have already removed the loose material and cleaned it up, but traditional Polyfilla (all purpose) is going to take an age. Assuming that I can actually get it to stick to the ceiling, as at the moment, it is just dropping off onto the floor.
