Default Power floating old concrete

Present workshop has a concrete floor which wasn't power floated

when
it was poured. (Not sure if I am using the right terminology. I'm
talking about that very smooth, powder free, almost glossy finish
often seen in warehouses etc.)

Any way to achieve this finish now on the floor which most be 18

years
old at this stage ?

I had thought about self leveling cement but I have heavy machinery
which I move about now and then and my experience of self leveling
cement was that it wasn't very strong and tended to crumble.

Any other suggestions ?

About 25 sq mtrs involved.

Any method of doing it piecemeal would be appreciated as I don't

fancy
having to pull everything out in one go.

What is your objective in powerfloating? If it is to get a smooth dust
free surface I can recommend the approach I've used in my last three
workshops, namely to lay 18mm OSB3 on the as laid concrete, and hold
it down with 2 1/2" No 10 screws on a 24 inch matrix. Overpainted with
floor paint it is a very durable surface that is good to work on. I
have large machinery (Mills lathes EDM machines etc) each weighing a
few tons which have been moved about on it several times. My fork lift
truck weighs in at 4 ton and that is in and out like a fiddlers elbow
with no problems. Important to use OSB3 as that is the damp resistant
variety.
