I have 2 year old fiberglass pool with 3" bullnose coping going over the edge and down. I do not have any tile, I like this look better. The issue is that some of the grout under the coping is falling off. Yes, I could regrout but I feel like it will have the same fate even if I get the right level of moisture (I assume that the builder put it on too wet). So I'm leaning towards some sort of caulking.
I've read numerous topics here where people were asking for similar advice, but it's all gunite pool/tile not coping/fiberglass. I've seen advice for Vulkem 116 and people were told to never use 100% silicone because they could never use anything else. Is this my case as well? Is there anything better than Vulkem 116? I've seen a suggestion for DECK-O-SEAL ONE STEP – Polymer-Based Sealing Compound but it seems to have pretty low reviews online and it's twice the price.
So to be clear, the grout under the bullnose coping, where the coping makes an edge with the fiberglass wall is falling off and I want to fix it. Any advice? Thank you!
