Product suggestion to seal gap above skimmer

[Dunn08]

Pool build is done and we’re starting to enjoy it.

The builder left a fairly decent gap above the skimmer and surrounding vertical tile pieces on both my skimmers.

I’m thinking of stuffing some foam back rod in the larger middle gap and sealing with a waterproof caulk instead of dropping the water 6” like the PB requested, for them to fill it in with cement.

Can anyone request a specific product that will work well for this application?

Thanks in advance!

Our PB used the same grout as where the waterline tile meets the coping and it has held up well. I wouldn't want it submerged while it's curing, but it should handle splashing and some absorbtion just fine. I would try and keep the skimmer at the lower level for the first 30 days, but I don't see why you would need to lower the water level beyond that for installation or curing. Anything that falls off as they trowel it into place should easily be picked up by your robot. In fact, for best adhesion and weight support, I'd have them pull the coping stone above the skimmer lay down a good layer of mortar first and then finish grout it.
