How to secure old sq head nails from pop up in old floor brds?

I have old pine boards and want to refinish but old nails keep popping back up. Do i glue them down before sanding and finishing? Is there also a way to harden the wood to resist gouges?

    The boards are loose, which is why the nails are popping up. Is the floor old enough to be historic? By square headed nails, do you mean "cut nails" or are they decorative nails?

    Without being there to see the floor, and assuming that it is a modern floor, I'd want to take the square nails out and replace them with screws followed by a wooden plug.

    When you do get to the finish, buy the best floor finish you can afford. One with aluminum oxide will make a much harder surface than a plain polyurethane. The price will look insane, but for durability and longevity the money is well-spent.

      The house is about 50 years old and i suspect the nails are old as the house was built by the former owners who were antiquers & hoarders. So is there a way to keep the old nails, and prevent them from popping back up? And thank you for the advice on the poli. Good to know.....

    Pine is a soft wood as opposed to oak, that is a hardwood. You can protect it with polyurethane.

    Best way is to remove the nails and screw the boards down. Use at least three coats of a water based polyurethane. That should be enough to protect the floor. That's what I always do.
