We have a little vinyl pool with a small concrete deck, built around this small concrete deck is a much larger wood deck. The wood deck is quite old and needing to be replaced, my wife and I are wanting to just redo the entire wood deck in concrete. My uncle has cool deck on his deck and he swears by it, Cool deck seems to get mixed reviews on here though. What are the pluses and minuses for it ? Is there anything better, also can it be poured on an already poured slab as I'd like everything to look uniform.
