Can't imagine why you would want a super smooth, polished concrete
finish for a sub floor that Pergo, ceramic tile, or anything else is
going over. Pergo, ceramic, etc floors are installed successfully
every day over ordinary construction slabs, plywood sub flooring
etc.
And as others have pointed out, for existing construciton,
particularly if it's wood frame, you have the issue of supporting the
additional weight. There are methods to deal with leveling your
floor prior to applying most flooring products without going extreme.
