Short answer: it doesn't matter; the same repair is required regardless. Slightly longer answer: leaving a plaster pool empty tends to result in delamination; I've speculated on plausible reasons, but I've never seen proof of a particular cause.

As far as repairing it, being that most of this work would have to be done in-house and we don't have any expert advising us on the ground, it would seem to make sense to me that the best option would be to stabilize the problem , and once we're sure that we're on the right track investing in a full repair.
Sounds like you're saying, "We need to find out how to do it right . . . and then do it that way", to which I can only say, "Of course!".


Just to clarify your actual repair recommendations, you are suggesting that I first fill in the holes with patching concrete and then repainting. Furthermore I should tap out the entire pool finding delaminated spots. Once I do that what should I do, should I break off all the delaminated plaster and then patch them and repaint them?
Unless you are ready to replaster, I would NOT recommend knocking out all the bad spots: once you do, patching may no longer be an option. What I am recommending is that you investigate the extent of the problem, so you can be better informed.

You've already told me that you don't have the budget to 'do it right', so I'm suggesting you take the time to inform yourselves as much as possible, so you can repair things the 'least bad way' possible.


Also I would like to ask you, I'm not sure I understand why eventually all the plaster would have to be scraped. Is it because the delamination would just continue and continue and I'll just have to keep on repairing it?
Properly installed plaster, kept submerged, doesn't delaminate. Whether 'doing right' requires just patching or a complete redo depends on what you find, when you check out the rest of the pool.
