Hello,

I have a fiberglass pool and need to know what I should use to seal the gap between the bullnose pavers/coping and the edge of the fiberglass pool?

Thank you!

I suspect two options. Either chisel out the old in that area and press in some new grout, or look for some polyurethane caulking. Either way may not be a perfect match, but if your main goal is to keep insects and water out, that may be it.

I believe your builder left it open on purpose. Ask him.

It lets any water that gets under the coping to drain.

Show me some wider pictures showing if the gap goes all around the pool.

Also show me pictures looking down at the coping and deck.
