Anyone have experience with this? Who should I contact about the draining of the pool, I know there is a proper way to do it and not mess things up.

DO NOT drain your pool yourself. It can pop out of the ground and you are screwed. Professionals will come and drill holes in the bottom to relieve hydrostatic pressure.

ive drained my own pool at least 5 times. However, there is quite a gradient between the pool and the street so i doubt the water table was ever very high.

Are you sure about painting it though? Is it gunnite?

Yes, its Gunite. I'm sure there is some special type of paint/coating to put on it.

Can you recommend any professional companies who do this?

Do you have gunite versus shotcrete. I am not sure one makes a difference, but in reading up saw a difference in concrete v gunite.

I am having a pool built, they used shotcrete....everyone uses in interchangeably with gunite, but there does seem to be a little difference.

And your plaster may be the issue, you may want to make sure prior to throwing paint on it and creating a mess.

Someone nearby did that and the entire thing including the concrete around it rose out of the ground by 2-3 feet. We are in the process of building a pool and haven't plastered yet. Due to the depth and water table we hit while digging we wont ever be able to drain our pool ourselves.

eta: there are actual pool renovation and restoration companies everywhere. just google local companies.

Not sure if some gunite is painted or not. I know my pool is gunite and then a plaster layer. You may want to reach out to NY Garcia Pool Plaster to discuss. That is who my pool contractor used. Not sure if they work directly with homeowners but I'd start there.

I know that fiberglass pools will be braced with metal or wooden posts to prevent popping out. Never heard of drilling holes in the bottom

if youre referring to an epoxy coating on top of gunnite, I would probably stay away from that. Its cheaper but I dont think it holds up. I had mine replastered and its expensive. Wish id have spent that money on a bunch of dirt to fill it in.

I have drained my pool down twice, you just have to make sure the bottom of the pool is higher than the water table. We live on a canal so it is SUPER easy. If the canal is down far enough I feel comfortable draining it.

Likely plaster and not paint if OP is talking about a gunite or shot Crete pool. It’s not cheap but should last 10-15 years. I’d almost certainly call my pool guy if I were to drain my entire pool as it is below the water table and would really frick shite up if it popped out.

Why does you pool need to be refinished? I ask because if its a plaster coating and its stained it can be drained and scrubbed with liquid chlorine and return to near new. However, if the plaster is cracked, chipped, pitted, etc then yes it would have to be replastered.

my pool is only 8000 gal and it cost me $7000 from a "value contractor". It doesnt look great but some of that is probably my fault

Reading comprehension is your friend...

Also, many older pools don't have a relief valve.

ETA: And you troglodyte--you drill the holes, pump the drain water out, patch the holes and paint.

for those concerned about draining the pool, they normally have a drain on the bottom that opens up to the ground below. If you are worried about the water table being higher than the bottom-ish of your pool, you need to open that plug to equalize the water table with the pool. As long as you do this and pump it out slowly, it will not float. Just leave the drain open the entire time its empty.

If you truly live in an area where the water table is very high, I dont know what to tell you. call a pro
