We're doing a new construction and the driveway and patio will be prick pavers in FL where there is a lot of rain, humidity and mold potential.. While sealing sort of makes sense - I've also read things saying it's bad - could possibly seal in things you don't want under there, wears unevenly, requires doing over and over and possibly stripping and all kinds of other maintenance. This gives us reason to pause and maybe just say no thanks. Obviously the guys selling sealing are going to tell you how great it is. Input would be appreciated.
