Advise on refinishing my wood floor

I want to refinish the wood floors in my bedrooms and I would like some advice before I get started. All the floors are in good condition except for 1 deep scratch about 3 1/2" long in one bedroom. Do I need to sand the whole room just for that one scratch or can I just sand it out by hand? Since the floors are in good condition can I just go over the floor with a top coat of polyurethane, if so is there anything I have to do to prep the floors before I start? Also, If I didn't complete all the floors the same day would you be able to tell where I stoped and started?

No Pro...but...

If the floors are in good condition except for the one scratch...I'd probably carefully use a stain stick (if needed) and an artists brush for a topcoat finish just on the scratch. You'd be amazed what a good professional or thorough DIY cleaning could do.

Oh....if a complete refinish is desired...I believe you need to screen (light sand) the whole thing and then topcoat. Yes it would be better to do all at once unless you have transitions of some sort between rooms. You also need to ID the existing finish.

Unless you sand deep enough to remove the scratch [would also remove the stain if any] you'll have to fill the crack. I'd use Vic's advice and try that first.

You need to sand the entire floor before you apply a fresh coat of poly. You don't need to sand deep, just enough to scuff up the old finish so the new finish will adhere. Don't forget to remove the sanding dust before you apply the poly!

Thank you for the replies. I am not sure what the existing finish is, and I was planning on using water based polyurethane. Does it matter what the existing finish is if I am going to lightly sand the topcoat anyway?

I'm not fond of apply water based poly over oil base. Supposedly as long as the oil is sanded, the water based is supposed to adhere - I'm just not overly competent that it will

I don't know if this will work with poly or not but you can give it a try.
