Read Andyc thread about palm sanders with great interest. I’ll be buying one today, high amps and high rpm seem to be most important. This will get heavy use for the sanding following paintshaver, then little use as a DIYer.
I only want to sand once, this is not furniture refinishing. What grit would be best as prep for painting?
Thanks
Kevin
PS Put some new blades on the paintshaver, very happy with the performance!

I'll be interested to hear what the pros suggest. I just started the trim on my porch using 100, since that's what I had on hand and the surface was already in pretty good shape. Too rough would not be good, I suppose, and too fine would defeat the purpose of sanding. When I buy paper for the rest, i was thinking of getting 80 grit
Assuming that your siding, like most others, is one of the soofter woods like cedar.....
I'd probably use 80 grit.
Followed by an oil primer, and two topcoats.
Stripped ( heat gun and shave hooks) a HUGE house last yr. All wood was cypress and both the 'Pro" painters and I arrived at 120 being the best for that work.
I don't know what kind of surface a machine like leaves, but in reality, anything finer than about 150 is gonna cost you more in the long run, it loads or wears too fast for sqft you get sanded, but soft woods like cedar ( I have to disagree with the mention of that) can get fuzzed and over abraded easily. If the sanding is straightline, go for it,but an RO will eat some wood pretty fast and still leave some decent sized squiggles that may not show till the primer hits it.
Google Pics for an air file, like autobody shops use..it takes like 2" x 16" paper and sands in a straight line, perfect for siding, but uses a lot of air.
All that said, LOL, try 120. and forget the garnet junk, go for the Norton or 3m pro stuff.

Went to the paintshaver site, they have 24 grit paper for the sander they sell. Seems like it fits a buffer, maybe lower rpm, so heavier grit?
I have to buy a sander, leaning towards 1/4 sheet sander to avoud swirls. Rigid is over 2 amps, and 14000 rpm. Can't find the PC 330 everyone is talking about at HD or Lowes, and I don't want to wait for delivery. Hope to sand and prime the area I stripped yesterday.
24 ? Geezus. Thats more like abrasive planing. Heck, a rock is 0 grit..LOL
Rigid should do ya good, you may buy a few grits and experiment for best results of wear vs. clogging. I'd rather sand raw wood than old nasty bits left behind of paint. That shaver sounds like a good tool for siding.Spheramid Enterprises Architectural Woodworks

They show it doing clapboard and shingles, which allows it to ride along the edge of the board above. Since I have B&B, the middle 2/3rds is freestyle and I was concerned it wouldn't go as well, but so far no problem.
