We have a 32'x'16' in-ground pool with surrounding concrete patio that over the years has become very rough with weathering (lots of exposed crush), which makes it very uncomfortable to walk on in bare feet. Would be nice to use one of the rubberized products out there to re-finish it but those tend to be pretty expensive, so I'm wondering if anyone has any recommendations for something to just resurface it... almost like a self-leveling product, except something that won't all run off (those tend to be pretty thin, and most of the patio slopes pretty steeply away from the pool). Can I maybe just mix up some fresh concrete without the gravel and spread it on smooth?
