Hi all,

Im trying to refinish an entire floor that was super distressed. Used a drum sander to remove of the scuffs and minor buckling on the edges. However, after applying the first coat of polyurethane, some parts of the wood was darker than others..is this still fixable?

Any tips is appreciated

It looks like you have not removed all of the old finish. Are you using a water-base poly-urethane to coat your floor? It will look much lighter on bare wood than the old with finish that is not sanded off. Sand diagonally with 50 grit both ways and then straighten it off to clear the old finish, spot seal with your finish, then apply another two coats to finish.
Of course if you don't care about the color, you will just need to add more coats of finish to protect what you have, assuming that the floor was cleaned well before starting sanding, and the old finish was scuffed up during the sanding process.
Radiators can cause the flooring to cup, from water damage, which makes it harder to sand smooth with the same amount of passes as a flat floor.
