Hi. I have owned this pool for about 3 months now and it looks like I've got plaster delamination. I believe the plaster is original from about 1997. I have one spot where the blister has cracked open and the plaster came off to a depth of about 1/4" and there are more blisters that will eventually break off. The pool has about six patches from the prior owners repairing it.
In all, I would say I've got 2-3 blisters maybe 6" in diameter that will be 1/8"-1/4" deep and a couple dozen blister spots that are 1-2" diameter and less than 1/8" deep.
I understand the ultimate fix would be to tear out all the plaster and re-do the whole thing. Any idea how much that would cost?
What is the viability of fixing these spots? And how?
Also, I noticed that all the prior repairs are square in shape so it appears that they cut around the hole, chipped it out, and then replastered. Is that the way it needs to be done?
Can this be a do-it-yourself job or is a professional needed?
See attached pictures.
