Hello, I’m experiencing intermittent grout cracking between my coping and pool tile. The tiles and coping were re-done in 2021 and the pool is salt water. I presume the cracking is largely due to water contact. Unfortunately the single skimmer is set quite high so I have to keep the water level a bit higher than I’d like.I have seen some epoxy products and I also have some plaster patch that I could try too. Happy to consider any recommendations. I presume this mostly cosmetic but I do want to prevent water from getting behind these tiles or under the coping as I know salt water can be corrosive.
Hoping to DIY this as the grout cracks are quite small and a good portion of it is holding up well. Perhaps the sealant didn’t get to the joint.
Also - please excuse my expansion joint calk job. Need to clean that up next weekend.
