Our First Time Refinishing Hardwood Floors - What Could Go Wrong??

Let's refinish these floors! We were lucky enough to find hardwood under all the carpet in our home in the last episode. In this video, we go through the process and all the steps on how to properly refinish your hardwood floors. Just as a heads up there is a LOT of sanding haha! We use some new and powerful tools to accomplish the task and we are super excited to apply the finish to these floors next time!
Thank you for watching and hopefully you found the video helpful!

Nice job. Been doing it for over 20 years and you did great. Nice to see people taking on projects and crushing it.

[@GoldenKeyDesign]

Thank you so much, we really appreciate it!

[@elizaangelim7533]

How dusty it can be for the rest of the house? I’m asking because I’m doing the sanding before moving to my house, but just on the main floor. It’s a townhouse, but I’m wondering if the dust it will be really bad for the upstairs rooms. How bad the cleaning part it will be?

[@elizaangelim7533]

Btw, good job!!!

[@GoldenKeyDesign]

@@elizaangelim7533 It is not horrible, but I would just block off the entrance to the upstairs with some painter's plastic to be sure

[@emilysze1145]

I have a question for you! My flooring was laid at an angle. What direction would you sand the flooring? Do you go with the angle or just run the sander in a straight line?

[@PcGamer38-md4sz]

This video brings back memories. My wife and i did our floors in our new house a few years back. It was definitely more work than i expected. After it was all said and done, i wish i had just hired the pros. If your thinking of doing this as a first timer i'd suggest giving some serious thought to it. In the end we didn't save as much as we thought we would and the work was tedious. Sanding imperfections don't show up until you apply the finish and then you have to redo that area. If your not careful you can ruin your floors.

[@zhaoyoki3915]

Use osculating tool with sanding attachment should be easy for the corners! So glad you encourage Bianca to try scary power tools! You go girl, woman can be as handy!

[@GoldenKeyDesign]

We actually tried that, but the sand paper gummed up so fast. We found the paint scraper was more efficient. And thanks for the encouragement!

[@pound6599]

So glad to see that you used the drum sander and edger. I see so many people use the flat orbital sander as the main sander.

[@GoldenKeyDesign]

It really sped up the process!

[@nathanparodi8312]

My wife and I are going to be sanding our hardwood flooring soon and this video is giving me complete confidence that we can do it. Your floors turned out awesome! Nice job!

[@brettrush]

I just started with the Sq buffer sander, spent all day on 1 room without finishing it. Just watched this video and will rent the right sander! Thanks for the confidence.

[@franklin9613]

Always sand diagonally because it prevents the sander from creating waves. Sanding with the grain alon without crossing the floor again diagonally is a no go professionally speaking. You won’t see it until you apply the stain. It may look flat but it snot.

[@GoldenKeyDesign]

That is a great tip, but only if your floors are already cupped. Ours were very flat so diagonal wasn't necessary. We already have applied the stain/top coat and the floor is perfectly flat

[@franklin9613]

I just redid two large floors myself after watching a bunch of KZbin videos. It made me feel better to know it took you 5 days to sand everything working together, it took me two to sand both of mine. It looks great! The color change is worth it.

[@dormandavis2767]

It was really a wise move for me to purchase a sander through Home Depot which I did get used for $700. I know this sander it’s a triple head sander retail for about $3000. It was money well spent because it took quite a while to do two houses and I don’t think I could rent it for seven hundred bucks. If you could buy one used that’s the best thing to do.

[@GoldenKeyDesign]

Nice! That's a great price

[@alabama_pinball]

This is super helpful, thanks! About to attempt for my house. Do you have a consumables breakdown for how much sand paper, tack cloth, etc you used?

[@synnectdevelopment]

Great job and video. Informative and encouraging About to try it myself on our 25 year old hardwood floors.

[@RadioJonesy]

I enjoyed this vlog , love the live music 🎶

[@AByachtgroup]

When you keep a pile of the dust and you mix it with wood glue you can fill all the little holes and the cracks between the individual boards. This way your self made filler will have the exact same color as your base floor. Unfortunately you will have to pass again with a square sander after this. And you have to make sure your floor finish will stick to the wood glue

[@GoldenKeyDesign]

I used the saw dust trick when plugging the few larger holes in the living room. Works great!

[@Allen-789]

OMG what filler used for those 1,000 nail holes? Thanks

You're only sanding while pushing the machine not pulling? Does it only work in one direction?

[@roseanneroseannadanna9651]

Good job guys! My cuz and I just bought my sisters house to flip bit sadly she screwed up her once nice hardwood floors by by putting a darker coffee finish over the lovely amber finish it had when dad bought her house. She did it herself and the results are horrendous. She did the work during the plandemic era! I am a retired constuctioneer and have over 35 years in in all trades except re-finishing hardwood floors. Your videos has given me hope in my ability to take this task on!

[@NF-kk9xt]

Do you mind sharing what type of sealer you used for the floors? Also what steps did you take after finishing sanding? I am going to refinish my 50 years old wooden floor and I want to retain the natural wood finish. Great vedio and was very helpful!!

[@galileavasquez9434]

Great video! Would you mind providing a cost breakdown?

[@SydneyTrip]

Hi, as for the edging machine, what sand paper grit number you use first for your hard wood floor edging? what is your 2nd grit number sand paper for edging machine, and the final grit number to go on edging machine? Same questions are for the drum machine: what sand paper grit number to go first on your drum machine, then 2nd, and third? I just hired a edging machine today, and had a go with grit 60 on the. machine, but it didn't off so much as so in your video. Am I support to use a lower number grit: 30 or 40?

[@jobbe-wijnen]

Go with the grain only and you will get a wavy end result. Go diagonally too.

[@Orikumi]

Can you sand new hardwood floor with square sander

[@BrandyHarper]

Would you recommend doing the edges first?

[@shaileshpatel3607]

Great job explaining steps, it would help if you spell out all costs to rent, sand papers, how many sq. ft, how many bed room, how many hours it took to do sending?, I am trying to decide if it is worth for me to do myself vs hiring someone

[@ShadowMoonFarms]

Thanks for sharing

[@GoldenKeyDesign]

Thanks for watching!

[@ds61821]

Did you try Oxalic acid to try to lighten stains in the flooring? Furniture restorers use it and often stains disappear or lighten significantly.

[@GoldenKeyDesign]

We did not, thanks for the tip!

[@parkerlewis3774]

What was the square footage of this project? Trying to figure out how long to rent the equipment?

[@GoldenKeyDesign]

This was about 1,000sqft of flooring

[@DBos77]

How far did you get on average with each edge sanding pad? Thanks

[@diverdave4056]

my oh my ... you need to run the sander on an angle across the floor in order to get a better smooth surface

[@joe-say-did-it6201]

@6:27 your edging backwards, left to tight on the edger at all time. yes you can run edger on stairs, not easy though.

[@gbcubed]

Curious why you need both the belt and square sander?

[@xcv4444hh]

Quick question: Why don’t you just use square sander for the whole floor? Sorry, I’m completely new to this.

[@GoldenKeyDesign]

It’s not aggressive enough. It would take much longer to sand through the grits. The square buff sander is just used as a finishing pass

[@slowjok3r]

Did you consider removing all the floor trim before sanding? It would have helped you get closer to the walls.

[@GoldenKeyDesign]

You should check out the previous video where we tore out all the carpet. In that video, we took out all the shoe molding so we had more margin when sanding up against the walls. We will reinstall new shoe molding after the floors are done 😁

[@ToInsaneTooCare]

There should be no need for that. A proper setup edger should get you right up to the trim.

[@thelksaddress]

I’m with Bianca, I wouldn’t want to use that drum sander 😅 floors look great though!

[@josholdham4750]

Thunk 😊

[@josholdham4750]

Funny 😆

[@GoldenKeyDesign]

😂 I had to make sure she tried it at least once!! Thank you 😁

[@bfxuan92]

I am wondering whether I can directly use square buff sander with 60, 80 and 100 grit instead of using drum sander?

[@Alloy7]

The square buff does not do a good job of removing old finish, and it takes a long time to make any progress. The drum sander looks scary, but you can practice with 100 grit sandpaper ( like in the video), and you can get used to sanding without ruining the floor.

[@northonalfonsoramirezvaler8189]

You should be going diagonal, not with the grain and you should only sand when moving backwards, don't allow it to sand moving forward. This is why you had to use so much sand paper. You were dragging material across the entirety of the belt. This doesn't happen when moving backwards. Super incorrect video which could make thousands of people finish their floors incorrectly.
