Take the 2-minute tour ×  Sections of the floor in our dining
room have worn sections, where the polyurethane coating has worn
through to the bare wood. Having the room emptied and properly
refinished isn't really an option at the moment. I understand
that you really can't stay in the house while the pros are using
their giant floor sanders and spraying polyurethane, and that it
takes several days.  Can I sand the section of floor by hand and
paint or spray polyurethane on the damaged sections? Is there
any way of doing this so it'll last for more than a few months?
Or are we best off simply waiting the several months or so it'll
be until we can have this done properly?  The research I've done
has yielded several opinions on the subject. This one, for
example, seems to outline a procedure I could do on my own, but
can I do this to just a section of the floor?  share|improve
this question does the wood show signs of wear also? Urethane
over damaged wood will lock in and highlight the defects. Actual
