Plaster patching

[RobDHW]

Hi all, when i was in my pool today I noticed some plaster problems. The pool is 50ish years old, plaster / gunnite, 13' x 27'. There are a few spots on the walls where the plaster seems to be gone / disintegrating. I know that in the long term we'll need to replaster, but in the mean time... is "pool putty" an acceptable patch? I don't know if it's been replastered before.

It's taken me a bunch of years to understand what "proper" pool maint. means - since i don't trust pool stores - and I'd like to do this the right way, but I don't think we can afford to replaster right now. The pool was painted 3 years ago due to blistering, but I didn't see any plaster problems then. I suspect that I'm to blame, due to low calcium & my lack of understanding how important it is.

Also - there are cracks where the coping meets the pool wall, should I putty these as well?

Thoughts are appreciated. Thanks.

If by pool putty you mean the underwater epoxy that's sold for pools, you can probably use that stuff until you manage to have the pool repaired properly. It's made for hard-sided pools.

So, I went ahead and am using Pool Putty to fix my plaster. Yes - it's the underwater epoxy stuff. Carl, I'm not sure what you meant when you said "it's meant for hard sided pools". My pool is gunnite / plaster / concrete. That's hard sided - right? I'm hoping it lasts a few years.
I neglected to mention that the disintegrating plaster spots are fairly small - maybe the size of a $0.50 piece in most cases, with one or two being 4" in diameter.

Replastering is tough here in E. Central IL. We've been getting tons of rain & it's tough to get a pool drained long enough for it not to heave up when empty (or so I've been told) - especially this year, so far. Also, I'm not sure who I would trust to replaster the pool.

Thanks.

There are several plaster patching products for both above and below water line installation. Ez-Patch is one and it seems to get good reviews.

Sorry....:(

"Hard-sided" just takes less time to type than "Concrete / shotkrete / gunite / tile /plaster" as opposed to vinyl and fiberglass.

MAS985 - Thanks! I'll check it out.
Carl - No problem - I think intonation got lost the 1st time I read your response. I took it more of a "don't use it on vinyl" - which I don't have. Now I've got it.
