Do I need a replaster?

Hi,
We had someone come out and take a look at our gunite pool/spa because it seems the plaster has significant flaking, though it does not seem to be peeling from the concrete. They of course said I needed a replaster, and I'm inclined to agree just by looking at it but i figured I'd check here for a second opinion of sorts. We would redo both the spa (pictured) and the pool for a number of reasons, not the least of which is aesthetics - the plaster is very discolored (the blue under the chipped pieces was the original color), and we want the pool and spa to match, but if the spa is having this issue, I have to imagine the pool isn't far behind. We were also going to go with quartz plaster since from what I've read and been told, it lasts longer.

My other concern is that this pool is less than 5 years old which seems a very short time to have issues like this. I'm in the north east and haven't covered it in the winter. I'm pretty good at keeping up with chemicals, but I'd be lying if I didn't say I have definitely lapsed for a few weeks in checking them. If not covering it is a contributing factor, I'm not opposed to adding one for the winter. However there are other pools in the neighborhood that aren't covered, which have been there longer than ours, and I haven't heard of this issue with theirs.

I'm half hoping this is just a bad batch/mix or poor application by the original installer, who is not the same company we had come out. I'm not in love with having to do this, but it's a bit easier to swallow if I know it's not going to happen again in 5 years!

Thanks in advance for information or advice, regarding both the immediate issue and the future!

That kinda of damage should not be happening for at least 15 years. Something is wrong with the original application or the water maintenance has been very very bad.

This is actually somewhat encouraging. I'm definitely pretty on top of the chemicals 99% of the time. At this point I'm almost hoping the original installer did a terrible job. It's not great but at least comforting for the future. The new plaster company came highly recommended from someone I trust.

How was the water chlorinated and were you following a pool store for testing and chemical levels? Something (ok lots of time) they give really bad advise. At least compare what you were doing to what TFP recommends.

 
Welcome to TFP.

Your plaster wear is not normal for a 5-year-old or even a 15-year-old pool. Being in the Northeast has nothing to do with it. I am in NJ and got 17 years out of my first plaster run. I only redid it because of a rusting rebar problem. I am now going on 8 years with my replaster looking good.

Given your plaster quality, you MUST get a full chip out of the old plaster down to gunite. That is not often done in the Northeast and will cost more due to the additional labor, but it is foolish to put a new layer of plaster on that questionable base.

I have a salt generator for chlorination. And yes I do go to a pool store for testing, etc. I'll read that link, thanks!

Thanks for the reply. This will be a complete removal of the old plaster before replastering.
