If you don't know much about resurfacing wood floors, you will probably want to just ignore this thread. I know very little about resurfacing floors, but I was elected project manager of a floor resurfacing project on campus. I was hoping that possibly some of you could help me out with the figures.
Here is what I know:
Wood floors.
There are three rooms to be resurfaced, sq. footage adds up to about 650-850 sq. ft.(an estimate is the best I have at the moment.)
Floors are very old, and in horrible condition, but we are just going to sand and resurface them, not replace any wood. (budget)
I have 15 workers, including myself, that will be working long hours free of charge, so labor isn't an issue.
We are hoping to get the big equipment (Drum/belt sander and Orbital sander) for free for a while from organizations we are affiliated with, but for the time being, I am assuming 1/2 avg. rental price for the two combined. (I live in downtown Milwaukee if that matters.)
The plan for finishing material is the "Street Shoes" 2-part system, primer and sealer. It is probably sort of pricy, but this is a really high traffic area.
I have no idea what amount of sand paper will be needed or even what grits will be used. (100/150/200 was suggested however.)
We are hoping to get the project completed, one room at a time, as quicly as possible, and we only have 1 weekend for one of the rooms. (about 200sq. ft. foodle )

Any help with sand paper amounts, rental price ranges, or simply suggestions for how to go about the project, would be greatly appreciated. A budget estimate/approximate time frame, with the above criteria considered, would make me extremely happy, but that may be too much to ask for.
Thanks
