All;
My 30'x36' shop floor was "smooth finished" by 1 guy using only a hand
trowel. It was impressive to watch him work. Especially so since he had to
slightly slope the floor to a centrally located floor drain. The surface is
kinda
slick when wet but is very easily swept.
On the other hand, I had the alley way and wash stall of the horse area
broom finished to enhance traction. And that area is a B^t%# to sweep clean.
As an amateur, I certainly would not attempt to smooth finish any sized
area because it is possible to overwork the concrete to the point that you
bring the coarse aggregates to the surface which results in a rough surface.

Bottom line: I would not hesitate to hire a pro to do the work. It's hard
work and experience counts for a project that is "set in stone".
