Which type of sander should I buy, to touch-up the skimcoat after I
have spread it?

Random orbital, belt, vibrating pad?

Please reply urgently. I am buying the sander tonight. I appreciate
any input you have.

Dunno what you're calling skimcoat- assume some sort of patching/
leveling stuff for divots you'll pull out of the ply.

Given that, suggest you apply any such stuff sparingly, with wide
knives. If advisable, in multiple thin coats.

My first guess as to sander would be a 6" PC ROS (with vac
connection), and 60-grit. Combo I use for rough work.

For a floor prep my first choice would be to simply rent a floor sander
if there's any sizable area at all.

Otherwise, if you're just touching up small patches here and there, the
above choice is probably good as any. You have any other reason for
buying a sander? Might as well try to make it serve some future purpose
in life other than sit on a shelf forever.

If it's just the occasional nail hole and so on, and you don't do a lot
of really heavy work, I'd suggest you might find the 5" ROS more handy
in the long run and it will handle that kind of a job as well...

Really too little info to judge what you really need for the task...
