Question about draining/painting pool in ground hybrid pool

[CincyPhan]

Hey there - I'm new here and am excited to learn and engage.

I purchased a house in Ohio last June and have a kidney bean shaped pool that has a concrete floor/base with a fiberglass wall liner. It's about 28 years old and is in need of some cosmetic TLC, but generally (knock on wood) in good shape! My brother in law is a professional painter and has painted many pools before, but has never been a completed the entire processes, but after some research both feel we can do it.

I began draining the pool (about 1/2 way) today to prep it for painting on Saturday (pressure wash, acid wash, etc). It's then when I began reading some horror stories about pool walls collapsing, pulling out of the ground etc. It's every intent of our ours to paint as quickly as possible and have a pressure equalizer valve on the bottom, but with Epoxy it needs at least 4-5 days to dry.

What I was confident in getting this done this weekend I now have anxiety that it might be best to spend the money to have a professional do it - but it doesn't seem too difficult should it all go alright.

Any thoughts or advice? Am I crazy?

Thanks in advance for any guidance!

Painting a pool is crazy as it doesn't last! However in your case probably the only option unless you went for aquabright or polyurea.
If the ground is dry it shouldn't pop out of the ground, certainly not in a week.

A good idea is to find out where your water table is
