Default Floor refinishing: help requested

A friend of mine living near the coast in Massachusetts is refinishing her oak floors. She has sanded them to 100 grit. She then cleaned up the sawdust by mopping, which, of course, raised the grain (she wasn't expecting this).

I suggested that she sand to 180 grit before finishing. But here are my questions:

1) What grit is a floor usually sanded to?
2) Is it worth wetting to raise the grain and then sanding again?
3) What's the best way to get sawdust up off the floor?
4) How long should she wait after the last sanding before putting on finish?
5) Does she need to use a sealer of any sort?
6) Is the Home Depot floor polyurethane a good product for finishing?
7) Will two coats be enough?
8) Are there some questions I didn't ask, but should have?

Thanks in advance for your help!

Peter

I have no idea, I hired a floor guy. The floor guy said that Swedish finish last the longest so that is what we got.

Peter,
Sorry, I'm not going to be much help. I was pretty cavalier about my shop floor. I rented a floor sander at Home Depot, with whatever they recommended for the sanding belt. I did use a product from Home Depot that the paint guy recommended and put on two coats. But mine is not a finish like I would want for my house. It's great in the shop, but I'd certainly pay more attention for my home. I don't believe the finish was a HD brand. Oh, and I just vacuumed prior to applying the finish.

When I refinished the floors (yellow pine) in a rental building I own, we used a rental floor sander and I think it only went to 150 grit, which still left a raggy surface. We put on two coats of polyurethane and it held up well for the beauty shop that occupied the space.

After they left, I used the building as a shop for a year and we sanded the floors with an ETS 150/5 to 100 and put on two more coats of poly to get it ready to rent. A Veterinarian now occupies the space and the floor is doing well, but those claws are leaving marks.

In both cases, I swept the floors and then vacuumed with a CT33 with the floor attachment.
