What type of sander is best -- skimcoating a luan plywood underlayment, prepping for vinyl sheet
 

I am re-using existing luan underlayment floor, in preparation for
installing new vinyl sheet floor. This is on the advice of my
installer, who has seen my floor underlayment and recommends its re-
use.

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.

PS - I cannot stop the group from pontificating at length on my
situation. But please: if you must type 1000 words on the wisdom of my
project, at least throw in some advice about the sander. :)

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.

My first choice would be a belt, but if you've never used one, then can be
dangerous. Well, in the hands of the inexperienced, they can take away a
lot of material fast and leave you with divots and more work than you
started with.

The vibrating pad sanders are not much good for anything but the lightest of
work.

That leaves the ROS. Get a 5" or 6" and it will do a good job with no real
learning curve. Just remember to let the machine do the work and don't use
a lot of pressure.

Guys, thanks a lot.

More info: I will be spreading Dependable-brand gypsum skimcoat onto
divots missing from the luan underlayment. When I pulled the
perimieter-glued vinyl floor off, it tore sections of the top layer
from the underlayment.

Since these sections were a small percentage of the overall area, this
is why we decided to re-use the floor.

The random-orbital does seem like the best option. I will be sure to
buy one with a vac port. I didn't think a belt sander would be
necessary, and yes the vibrating ones don't seem to do much at all.

I am sure to buy plenty of knife sizes, too.

A random orbit sander will work fine, about $100 or less. If the
floor is large consider renting a floor sander, but you will still
need a smaller sander for the edges, corners. A belt sander is very
aggressive.
