Greetings,
I have about 400 sq feet that I'd like to strip and re-poly. The high
traffic areas are down to bare wood.

First, I can rent both a vibrating square sander and an orbital buffer
with sandpaper. Which is best?

Second, will I have to evacuate the house for a few days when I re-
poly due to smell/ fumes?

BTW, I looked at having a professional strip the floor for me - it'll
be about $320. I can rent a sander + paper for about $120. If
there's anyone in Southern Maine you can recommend for around $200
I'll gladly call. I'll poly it myself...

Thanks!
