This past weekend, we determined there were a lot of separations in the pool plaster, the last of which was done in 2014. I spoke with the pool company that re-plastered it last time and was told there are probably 2 or more layers beneath the last one. His suggestion is that we have all of the layers of plaster removed, down to the base material, and then re-plaster the pool.
At this time, we are awaiting the quote for this work and in the meanwhile, the pool will be closed until we can get these repairs done. We will let everyone know when this work is scheduled and the approximate completion date.
Below is a link to a Dropbox folder with some photos of the problem areas, These are not all of the problem areas, just a sampling of them.
