We just had a fiberglass pool installed and getting efflorescence ‘drips’ from the concrete pavers to fiberglass water line. I’m looking for a caulk product to apply in the space between concrete bullnose coping stone pavers and fiberglass pool to block efflorescence. Any recommendations? Thanks!

Welcome to TFP.

You can try Sikaflex®-1A.

However that will not address the root cause which is water runoff from the grass areas bordering the coping. That water will find somewhere to go around your pool.
