It has been several years since I’ve been on the TFP site, so apologies in advance if I’m posting this question in the wrong forum. Pool tile was replaced in fall 2020. A crack has developed directly above the waterline tile, pretty much all the way around the pool. I hope it’s visible in the picture. I’m wondering if I should repair this? If so, what material is best & where would I purchase it? Thanks!

Hi all, bumping this for visibility. Hoping for a reply fairly soon. We close in early/mid October and I want to make sure my pool is ready for our harsh winters.
Functionally, that crack is doing no real harm. I would improve the aesthetics with a bead of polyurethane caulk smoothed with a putty knife.
Regular caulk does not have the flex of polyurethane but polyurethane is more difficult to work with.

Do you guys have Sikaflex is the US? For expansion joints in concrete and under the coping tile you can.
Apply masking tape the edge of the crack. In your application I would just do the tile.
Apply sikaflex bead using a calking gun. You may have to do a little test of the whole process to discover how much calking you need to apply. Too much is painful and make sure you have a solvent and rag handy as Sikaflex tends to get everywhere.
Spray bead with spray bottle containing water and a little dishwashing detergent.
Slide a paddle pop stick ( either from an ice block or a bigger one from a doctor who asks you to hold out your tongue and say ahhhh) over the bead creating a nice curved expansion joint sealing the crack. Have a rag with you as you need to wipe the stick often.
You can use the side of the stick, or a scraper to skim the excess of the under side of the tile. Alternatively you tape this side also but think it will be difficult.
Once done pull tape off.

This guy goes on a bit and uses his finger over a paddle pop stick, but you will get the drift.

Thanks all. Great tips. Yes, we do have sikaflex. I use it yearly in the fall to keep the expansion joint between the coping & pool deck sealed.

Nice, I have 105 foot to get excited about when the decking is done. Can't wait for that one.
