my choice would be a planer
with reversible /disposable knives

that ‘diamond finish’ is just that
HARD

you could have several sets of knives for the planer
and use one for this wood alone
and then sand from there

going at it with sandpaper
will use up tons of it
at a high cost for what return you get

That finish is aluminum oxide and will KILL planer blades in a big hurry (voice of experience here!). I use a lot of flooring for my boxes and have found a drum sander with 50 grit paper the best tool to remove this finish fast. 80 grit also works well but require a couple more passes. I do use my planer to remove the grooves on the back side. If you can swing a drum sander, DO IT! I have 2 and they get used on every project.

another option would be to saw it off first
on edge on the table saw
or the bandsaw
with fixed fence and finger boards

Mark,

I wish I had that diamond tough finish on my hardwood floors, but I digress.

...back to your quandary.
When refinishing hardwood floors, often an industrial duty belt sander is used to remove the existing finish(es) and smooth the hardwood. It sounds as though a handheld belt sander may be your quickest, cheapest or only solution to salvaging that wood gloat.

A drum sander would possibly work but IMHO that finish would probably dull several planer blades and compound your frustration.

Have you considered utilizing the wood with the existing color and finish for your projects?
Personally I would shelve it and bring it back out when I come across just the right project for it and be ‘tickled to death’ to have eliminated the finishing steps on a project for once.
...just a thought :-)

I bet you my kids can scratch that finish in no time :)

It took them less than a year to ruin my hardwood floor ( factory pre-finished).

seriously, last weeking I tried to restore a side door that water had damaged.
I started sanding with a makita ROS with 80 grit. Gave up quickly.
I remembered that I had a rigid belt sander. Boy that thing is good.
I had the door all sanded and flat under an hour.

That will probably be the cheapest solution.

+1 for the belt sander. Hand held or stationary. After several boards with a planer you’d probably start burning with the dull blades.
Besides, sanders are what they use to refinish flooring.

Wow – fantastic information! It never would have dawned on me that this finish would defeat planer blades. It makes sense that it will take a super aggressive sander to strip the finish off. A drum sander is on my wish list as Is a
good table saw. I have been planning to upgrade the table saw first. Right now I’m going to put the table saw ahead of a good belt sander as well. I wouldn’t trust my current harbor freight table saw to slice the finish off. My cheapo saw has the worst fence imaginable. That leaves me with a bit of a delay before I can use this beautiful wood. That’s ok for now. The wood will wait for me.

A couple of other items. I considered using the wood as is. I had 2 projects in mind for the immediate future. One of them could actually use the current finish. I’ll keep that in mind.

The other thing is – using a chemical stripper did next to nothing except to take a little surface glaze. That is something at least but it takes a lot of expensive stripper for the little bit of finish it takes off.

Lumberjocks, you all are awesome! You quite litterally saved me from a huge disappointment. I can not thank you enough.

Howdy my friends. Many of you are about to disown me. I hope you’ll understand why I committed my lumber jocks sin. I hope you will find it in your hearts to forgive me. I … I… Oh why does this confession have to be so painful. I (shudder) I bought a harbor freight belt sander for $24. Yeah, they were on sale and I had a 20% coupon. I promise to speak unkindly to it. It won’t have a revered spot in my garage. I will never take it out to the movies with me.

I’ll tell you in secret that it took the finish off one of the boards in 5 minutes. I’ll upgrade at a later date but in the meantime, problem solved. All the votes for aggressive sanding were on the money.

The girl at the counter did not want to take no for an answer as she kept pressuring me to buy an extended service contract. When I told her the sander was a temp. She thought I was saying I was going to buy the more expensive hf model later. I wouldn’t call that too much of an upgrade.

Although it comes with a dust collector, you will need to supliment if you buy one. In my case, my jeans and t shirt did most of the dust collecting. ;)

Would it be quicker if you resawed it? If you did it right your blade would not get ruined. Table Saw as mentioned before but a little more scary and such short pieces to boot. Or just thrown the belt sander upside down in the wood vise and the dust collector hose on the end close to it and have a sanding party…..

Mark,

Your HF sander is a bargain and I believe that even if you have to buy 4 of them to remove the finish, you will still have a lot less $$ invested than had you bought a major brand and wore it out.

I would recomend that you connect it to, at least, your shop vac to keep the air clean as possible.

A major concern with this finish removal isn’t just the wood dust you are getting on your t-shirt and jeans and breathing into your lungs. You are also breathing in the micro particles of the aluminum oxide finish.
Our bodies can not break down or expell some of these new finishes. I’m not an expert nor even well informed on this particular finish but I would definately sand this outside with plenty of fresh air and at least an upgraded dust mask or resperator.
Err on the side of Safety.

gfadvm: can you or another LJ, offer any additional hazard/safety info on this aluminum oxide finish remmoval?

Best Wishes, Work Safely and have Fun. Grandpa Len

For a tool that will only see a hard days work a HF belt sander cant be beat. Ive got a Ryobi that i consistently beat the crap out of and it loves it. The only thing its used for is getting dirt and grime off of reclaimed boards. Its a great beater. Wear a mask for sure.

gfadvm is correct. I sold flooring- it is an aluminum oxide coating. Tougher than cast iron!

I have found that these type boards work really well for secondary lumber without removing the finish. Just turn it so it doesn’t show.

Chemical stripper. There are some good non-toxic ones that should make quick work of it. I hate belt sanders, they tend to make a mess of things (in my hands anyway, with a 36 grit belt)

Kova,

En Realmente – no tengo la sistema de extraccion de asserin. Era un chiste. Dijo que la sistema era mi pantalones y camiseta. En este caso, si desarmo, que vas a ver? Un Marcos sin ropa? No creo que vas a dicir gracias por un foto de un Marcos desnudo. JAJA. Gracias mi amigo por su attention y comentario.

Really Really good suggestions!

Until I read this post, I didn’t know there was such a thing as a card scrapper. You learn something every day!

As far as using one, gfadvm is right – there has to be something to grab onto. There is just nothing to get a purchase on. I’ll go ahead and remind how hard this finish is one more time. My random orbital sander with a 40 grit disk just barely manage to scratch up the finish. It didn’t remove anything noticeable after 5 minutes of sanding.

Granpa Len – You may have saved me from some awful lung disease. I have a good respirator I’ll use. I’ll try to hook the sander to my shop vac as well. I have been sanding out doors.

Hey Joe, What brand of chemical stripper do you like to use? I’d like something a little more aggressive and the gels they sell at the box stores only go so far.

As far as turning this flooring into useable stock, I really feel my problem was solved with the 18 X 3 belt sander. I did notice a couple of low spots in the wood when I got down to 150 grit sanding so I had to start over with 40 grit. I know what I did wrong on that count and I can avoid it in the future.

This board was the worst one of the lot so I experimented on it with the HF belt sander. It’s all kinds of warped. It only took 5 minutes to strip the finish. I’d say that was plenty fast for my purposes. Plus I’m pretty durn patient when it comes to trying to get the best look out of the wood. I didn’t say GOOD mind you, just patient. ;)

I have to ask your opinions on this, how could I NOT invest the time into the wood. It’s incredible! Really it is! Just ask me. :)

That is some beautiful grain. Once the finish is off then you can put blade to it (jointer/planer/hand plane) to mill it flat and take the warp out.

Citristrip has worked well for me in the past. My wife used to be into restoring old furniture. I find a good wash with some TSP and rough steel wool gets things moving as well before the stripper. Obviously you are going to have to sand after, but I think you were planning on doing that anyway

Mark,

Your efforts in salvaging your wood gloat has produced some beautifully grained lumber and we can all appreciate that there was no monetary cost in it’s reclaimation, other than your new sander.

However, to all, there are dramatic costs to health and wellfare in processing, repurposing and reusing materials without understanding the chemicals/processes used in the initial treatment for it’s intended use, i.e. salvaging pallets for ‘free’ lumber.
You must know how it has been treated/preserved before utilizing it for a project which may have adverse affects when coming in contact with food or my Great-Granddaughters teething efforts.

Mark, you have brought to light a subject who’s time has come, and we must get the word out to all of our ‘new to woodworking’ friends that may not realize, that because wood is a natural resource, it’s not all as safe as a pine board from the lumberyard rack.

Andy, (gfadvm), and others, thanks for your knowledge of the finish properties of this post.
We should remember as LJs that ‘if we are in doubt’ or have questions or concerns, however trivial, the only silly questions are those we don’t ask.

So again I say, ” Welcome to LumberJocks, a world of advise, opinions, and experiences, all shared without judgement.”

Mark, a ‘wink and a nod’ from Mother Nature for repurposing that lumber.

Work Safely and have Fun. – Grandpa Len.

I bought LumLiq wood for my great room and for the window returns on the new house! Glad to hear that the finish is that tough! Guess they do that to avoid warranty claims. They do sell unfinished lumber also so pay attention on your next dive!

I think I’d use your find for shelving boards or counter tops (pix is of my mud-room made with leftover $2.79/sq ft stuff).

Teejk,

Nice job there. The counter may outlive the entire house. Thanks for the shelf idea.

Grandpa Len,

I could try to interject some humor here but it’s not really appropriate. I got a real good look at the dust from the flooring finish. The sun was directly overhead and I could see tiny bits of reflective mater. Despite the beat down of wearing a respirator for 4 hours straight, I was thinking about your cautionary warning with gratitude. Thank you my friend.
