Last fall, we refinished our hardwood floors. The whole process took a good long weekend. Many wonder if it is even worth the energy to do-it-yourself. It is definitely a back-breaking job and it makes your house a crazy mess with sawdust EVERYWHERE! But the results are worth it.
Here is a break-down for those who are considering refinishing their own hardwood floors.

I’m just going to give a quick run down on the overall process. You’ll find your own rhythm once you get going.
1. Drum sander – 60 grit sandpaper – start at one edge of room and pull sander to the center of the room. Do same on other side of room. Meet in the middle. Make sure sanding start and finish marks blend well in the center of the room.
(I know this seems like a no-brainer, but I just have to say: go with the grain of the wood. Our floors had all sorts of deep marks going against the grain – not good. Also, if your floors are in horrible condition, start with a lower grit sandpaper and work your way up.)
2. Orbital edge sander – 60 grit – go in circular motions around edge of room getting as close as you can to the wall. (Warning: You will become a hunchback at this job!)
3. Repeat steps 1 & 2 again for another pass.
4. Now do 2 more passes with both sanders - this time using 100 grit sandpaper.
5. Vacuum and clean floors with a very damp rag.
6. Apply wood conditioner.
7. Sand with pole sander – 120 grit sandpaper.
8. Repeat step 5 again.
9. Ready for polyurethane application #1. Use watering can to make small puddle along a wall. Drag puddle using the lambskin applicator. Keep a wet edge – just like with watercolor painting. Add more polyurethane as needed, but not so much that you have a huge puddle at the very end. Kinda messy to clean up. If you do have extra at the end, soak it up in the lambskin and squeeze into bucket until excess is gone. Will make lots of bubbles in the bucket which isn’t ideal if you are going to use it. (Also, make sure you can end at a doorway or exit or else you’ll be trapped!)
10. Let dry for at least 2 hours.
11. Do coat #2 (just like the first coat). Let dry at least 2 more hours.
12. Sand with pole sander – 120 grit sandpaper.
13. Repeat step 5 yet again. (You’ll be sick of cleaning your floors by now!)
14. Apply coat #3. This should be the last coat if all went well. Wait about 72 hours before you put furniture down.
All done! Yes!

In this last photo, it is interesting to see how paint color and lighting can change how the floor appears.
Good luck with your floor refinishing!
