If you’ve adopted the common property memorandum, it makes it quite clear paint is the responsibility of the owner. (The common property memorandum is available on the fair trading website)
The Memorandum no longer addresses the issue of damage to paintwork caused by repairs to common property. I have always understood that damage caused while effecting repairs were the responsibility of the owners corporation, and that includes paintwork.
It makes no sense to me that an individual owner should have to pay to repaint their ceiling when the damage was caused by other parties in circumstances beyond their control.
If the prior condition of the ceiling is an issue, then the payment should be proportionate. Just my personal view but I would take it to the strata insurer, and maybe Fair Trading, to see what they said.
