Painting Hardwood Floor.
#1

I have an old discolored hardwood floor in the kitchen that needs to be covered up. I do not want to put laminate down until I can afford to replace the hardwood with plywood, so I want to paint it for now. I have three questions:
1. What should I use to fill in gaps/cracks between the wood slats? I need something that is somewhat flexible and won't crack when walked on.
2. Do I need to remove the polyurethane finish before I paint the floor?
3. What do I need to seal it with once it is painted to keep it from getting scuffed up?

It tends not to be recommended that you fill gaps between hardwood flooring boards. Boards tend to expand and contract across the boards due to changes in temperature and humdity, thus any filler will tend to pop out and/or deteriorate.
If flooring is in good condition and color is acceptable, the surface can be 'screened' (roughed up) to acceptnew finish in order to renew floor. This can also be done to accept paint and additional coats of non-yellowing polyurethane to seal and protect paint.
