I recently bought a home with a fiberglass inground pool. While cleaning it I've noticed this plastic track around the top edged of the pool which appears is supposed to cover a gap between the pool edge and concrete patio transition. In several places this has come loose and looks horrible, while in other places it's filthy and I've not been able to clean it with any methods tried thusfar. It appears in loose areas the back was attached with some form of adhesive, while in other places it is screwed in. I've also observed what appears to be mud between the cement and pool edge in places, and when water splashes there dirt gets in the pool. Can this be repaired?
Thank you in advance for advice/thoughts.
