When my deck was redone several years ago, the contractor who poured the deck left a piece of plastic that sits at the top of my tile. This was part of the form to pour the concrete. In most area of the pool it looks good and provides a clean line between the deck and the pool tile. However, in some areas the tile has shifted and created gaps between this narrow piece of plastic and the tile, making it rather unsightly. See the photos below. The top one is one of the "good areas" of tile and the bottom is where the tile has pulled away from the plastic piece (and my attempt to repair it).
I have tried to "clean up" the bad areas by using tile grout in the gaps, but it is now cracking and falling out in some areas. I'm wondering if caulk would be a better solution to get a clean line similar to the other "good areas" of the tile in the pool. Any thoughts? Can I use a caulk along the top edge of the tile to fill in any gaps there and make this look better. If so, what type of caulk should I use? Thanks.
