I have a loose patch approx 2ft diameter on an overpapered lath & hair plaster ceiling.
I can get to the rear of the laths (loft).
Does the prop it & pour on loose mix plaster method work?
I envisage hoovering out the back of the laths, wetting with a spray, pouring on the plaster, move it around to try & get it down & around the laths, leave to set, remove prop whilst praying.
Any gotchas here? Any top tips here? Ordinary plaster? Bonding agent? Scrim/mesh?
TIA
