Last weekend I sanded out and stained a 100+ year old straight grain Fir floor in a room about 12 x 12. I have some water based satin poly to lay down this weekend. Everything I read says use a pad. At Home Depot the best I could find was a 7" wide pad with a holder than can be attached to a typical roller pole. It has foam as a base like a typical foam brush which is covered by about 1\4" thick pad of a micro fiber type material.

Anyone have experience doing this? Does this sound like the right equipment?

It says can be recoated in 2 hours but no more than 2 coats a day. I am figuring 2 coats on Saturday and another one or two on Sunday but I think I need to scuff it before the Sunday coats which I am not looking forward to. Probably have to do that on my knees although I thought maybe using my drywall pole sander if I can find a fine enough grit.
