To remove scratches, you can sand them using fine sandpaper or a sanding block. Then, use a coat of polyurethane on the floor to seal it. For more detailed information, you should ask your building maintenance team.

Can you give me some more detailed information?

Yes, if you’re using polyurethane, I can tell you more about it.  Polythene is a mixture of polyurethane and plastic that is usually used for coating hardwood floors.   You apply the mixture and allow it to dry to a hazy finish.  You can then sand the polyurethane until the color matches that of the floor.  There are two types of polyurethane available for this purpose: gloss and satin.  For a gloss finish, you should use a satin polyurethane and for a satin finish, you should use a gloss polyurethane.  To avoid bubbles or runs, wait for the polyurethane to dry before you begin sanding, and make sure that the floor is clean and dry.

Should I just do one coat of polyurethane on the wood floor?
