Our house on the second floor has a curve shaped outdoor concrete deck. This deck, historically had some water leaking problems (although we don't really know whether the water was coming in through the roof or from this deck).
Anyway, recently we are going through a exterior paint project, and the painter suggested to have two coats of epoxy-based paint on the deck. However I was thinking that maybe we could do one coat of Drylok masonry waterproof first, then two coats of epoxy-based paint. Would this work better and for water-proofing and sealing purpose, would this sound like a good idea? We have been using Drylok for our basement (below grade), and it seems to be working great, but I'm not sure if Drylok could also be applied for the outdoor concrete deck. Thoughts or comments?
here is a photo of the deck:
