Pool Painting

Came out well looks good. I hope somehow you got the good batch of paint and it lasts many years
+1 JP. We are certainly rooting for you. If it seems like we aren’t, we are just trying to go over all the +/-‘s. But no matter which way you roll, We root and clap. :)
 
Hey guys. After painting, I discovered a small hole right at the edge of the main drain. It is less than 1/2" in diameter (see photo). Water is oozing out of it very slowly. What would be the best product to patch this with? Also, could this have been a source of some water loss in the pool..... or not likely?

I have EZ patch 4 FS on hand. Will that work to fix the pin hole near the main drain ? Had some EZ Patch 1 FS, but ran out. If the EZ Patch 4 FS will work, that's great, but if not, please let me know what's best. I only need a tiny tiny amount.

Found this online. Would this be better than using the EZ Patch 4 FS?

How far does that hole go? Through the gunite?

For any kind of weeping cracks or holes in a cement surface, the only proper fix is to use hydraulic cement. But, in order to get good bonding, you’re going to need to open up the area around the hole and get all that epoxy paint off. Otherwise the hydraulic cement may not adhere.
 
Thank you. Is the Leslie's All-Purpose water proof cement the same as hydraulic cement, or.... is this what I need?

Yes. That should work. It sets fast so read the instructions carefully and follow the surface prep guide so it stays in place.
 
Thanks again. Was about to drive 20 miles to get the Pool Patch at Leslie's. Glad to know the stuff at Ace will work. It's a lot shorter drive! :)

Also.... could that have been a source of water loss? It seemed like I was losing some water last year and I couldn't find a leak... or is it unlikely that that tiny hole would cause any significant water loss?

Hard to say. How deep is the hole? Does it penetrate all the way through the shell? Is there a crack in the shell near there?

It also looks like you have some tiles to replace. You want to fix that as well because the gunite shell is NOT waterproof and will allow water to seep through it. So if the water is half way up the tile line, it's going to damage the bond beam there. That can lead to water seepage under the deck and cause damage during freeze/thaw cycles.
 
Here's is a photo of the small crack by the main drain after I ground away the surrounding paint and the finished repair. Sure hope I did this right. Looks like the trickle of water that was coming from the crack has completely stopped. It's drying now and I plan to let it dry overnight. The package says 28 days for curing. Yikes! I need to get this repair painted, let the paint cure, and start getting the pool filled. Not going to sit here for 28 days to let a small patch of concrete cure. What problems might I potentially run into if I paint over the hydraulic cement tomorrow morning? I don't see any other cracks in the shell near this one.

Yes... tile repair is needed... and is in the works.

I don't see any other cracks in the shell near this one.

I don’t know enough about these things to comment but rest assured I’m still rooting. :epds:

Nice to have a cheering section, Newdude!

I am keeping the bottom of the pool dry for now, but it is a pain because I have to run out to the pool and run the shop vac every 30 minutes or so. JoyfulNoise... or anyone else... how long do I need to keep this hydraulic cement dry until I can stop worrying about the groundwater seeping in on it (from the hydro-static valve). Also, we are supposed to start getting rain tomorrow morning and it looks pretty wet here in Chicago on Tuesday and Wednesday. No way I'm going to be able to keep that dry after tomorrow morning.

Also, still looking for input on painting that hydraulic cement. At this point, I plan on doing it toward the end of the week after I can dry out the bottom of the pool from the rain that is coming.
 
The 28 day rule is usually quoted by cement product makers as to when the product will achieve its MAXIMUM compressive strength. Typically speaking, most cement based products will hit 70% of their maximum strength by 7 days or so. Less than that, and the strength is degraded.

Will that matter in your particular situation? Probably not. If you were pouring a new deck or sinking a pier for a new footing, I would say you should wait. Patching a small crack or hole … probably not a huge deal. Wait until it feels like you can get the paint to stick, then paint it. Worse cones to worse, when you’re removing this paint in a couple of years, that hydraulic cement will crumble a little and you’ll have to fix it again.

Thanks for the pointers. Any clues on how long I should wait... 1 day... 2 days? The area will get wet tomorrow due to rain in the forecast. Does that create any issues for this hydraulic cement? I'm not going to be able to keep it dry after about 8:00 am tomorrow. At this point, I hope to get it dry after the rain stops and probably paint the patch on Thursday.

You can typically paint hydraulic cement within 24 hours of applying it. It will cure in place, just more slowly. Even if it gets wet, it should be fine. It really just needs 24 hours to set and then you can work over it. In your application, painting over it after 24 hours should be fine. I wouldn’t stress too much about it.

Thanks, so much. Rain is coming later than expected today, so I think I'm going to do the touch up this morning. If I get several hours of dry time with this epoxy paint it seems to stand up pretty well to any water by then. Will also try to speed up dry time with some fans. Looks like tile repair will be done tomorrow. Hopefully, I can start filling the pool over the weekend. That will give me 4-5 days of cure time for the touch up I'm doing today. Thanks again for the help. I really appreciate it. :)

Touch up complete! Now I just need curing time. I have those "helicopters" all over the pool today . Thank God most of the paint on the pool is nice and dry by now. Really battling the elements when painting a pool this time of year!!! It's disheartening when this Crud blows all over the wet paint, but I've learned to just let it sit. When the paint hardens after about 24 hours I can usually clean it up with a power washer.

Question: I see water sitting in the pipe that runs from the main drain to the skimmer. Seems like that should be dry if there is no water in the skimmer. Does this indicate some type of in crack in that line?
