Proper Sandpaper Grit for Sanding Oak Floor

Sorry, and I mean this in the nicest way, you guys are nuts. I've had
several floors finished to 100 and 120 and once the high gloss coating is
applied I've found myself sliding along the floor. Are you going to sand
between each coat as well?

A floor sander is probably a bit brutish for finer paper. The key for
polyurethane issue is nonsense.

If it is good and flat at 120 grit and you want a very fine finish then
hoover up all the dust, give it a good wetting with clean water, let it dry
completely and then sand smooth with 150 grit paper in an orbital sander.
The water will raise the grain, aprocess i don't have time to describe right
now but you will see how it works when you do it.

Hello there,

I stopped with 80g on my Bosch 1250 6" ROS. Remember, you will always be 5'
away from the finish!

Thanks,

David.

I'm pretty sure he means you are not going to be looking at the finish on
your hands and knees--assuming you are of average height, your eyes will be
about 5 feet from the finish.

I used 150 grit screens between coats, with a 12"x18" orbital floor sander.

I'm not understanding what you mean by "5' away from the finish". Possibly
you meant 5", but either way, please explain.

Thanks

I ended up finishing it off with 220 on a pole sander. It only took about
45 minutes, and was a good upper-body workout.

You can always make your own using an old flannel shirt, spray on adhesive,
higher grit sandpaper and a hole punch.
