Not really. Some hairline ones that had been filled in before it was last painted and they seem to be still pretty good. My pool deck is tiny compared to yours lol!
Ours is basically our backyard, pool about 15' from the house. I am happy with SunDek but it's applied by a contractor so shop around.. I had another company quote a different epoxy coating and they were about $5K more.
I think it honestly comes down to how they prep the surface.
