I'm about to embark on my first floor-refinishing adventure and I'm jumping in the deep end — not just refinishing, but also staining. And not just staining, but staining a light wood pretty dang dark.

I've read that, after sanding, I should hit the floors with some water to help them absorb the dark stain and prevent blotches. Do you recommend that? Any other tips?


It depends on what type of hardwood you have. Some species like pine/maple are almost impossible to stain dark without blotching.

I have stained oak floors to almost black. We picked up the darkest stain we could get - sorry I don't know the name but this was 8-9 years ago. We sanded the floor then went over with a fine sanding. Then we painted the floors with water. Not sure how to quantify the water but it took about one hour for it to visibly look dry. After we applied the first coat of stain. Just rubbed it on with a rag and another guy was behind me wiping off any excess. We did this three times total - one day between coats - no one was allowed in house but us. 48 hours after the last coat they threw on the finish/poly. Looked great but the family had to go on vacation and trust us at their house (grandpa was letting us in).

My advice to you is put a few pieces of the wood material together - if you don't have any pick some up at big box or craigslist. Go through the process - sand, water, stain, stain, stain - and make sure it looks like you want. You won't get the perfect black finish with all woods. You might find that you might want a different tint if you can't get that. Also I would not do the water if you don't have a hard wood - it will cause blotchiness. Also putting on gobs of stain will not make your floors darker it will just make it look like a kid did yours floors. You will need to do more coats to get it darker. My guess is after 3 coats you start to get diminishing returns. Some people do 2 coats, some do 3. Maybe on your test you do half 2 coats and half 3 and see if you can tell.

Edit: On a side note to staining. If you are doing the floors totally DIY. Do not over sand your floors with the course grit. If you over sand with a course grit, you will get swirls. If you leave those swirls then it will be very important that you get almost black. Because you will end up with a chocolate floor with very black swirls. The swirls will take to the stain faster and the pattern will show. Not trying to scare you here - just go easy on the sanding and do finish sand it.

  • Pretty sure they're oak. Original from a '20s townhouse. We have about 800 square feet to do, is the hands and knees method necessary for precision or could I use some kind of sponge mop? – Luke Baumgarten May 25 '13 at 5:28

    We used a paint brush roller and water. I don't think it matters that much as long as it is even. Also see my edit on sanding. And with old strip oak you can get it pretty dark. I would still do a test batch with a couple strips. – DMoore May 25 '13 at 5:31
  • That's awesome advice. Thanks for all the help – Luke Baumgarten May 25 '13 at 5:35

    Good luck - 800 sq feet is a good size project. Also don't forget to clean obsessively after sanding. – DMoore May 25 '13 at 5:36

    Minwax makes a pre-stain conditioner that works pretty well. Be very careful using water, it tends to raise the grain of the wood and can result in a less than smooth surface. If you are using an oil based stain, make absolutely sure the wood is dry. Oil and water don't mix well, that is why I like the minwax conditioner instead, it is made to work with oil based stains. Good luck. – shirlock homes May 25 '13 at 13:07

Here is an account from Popular Woodworking on Ebonizing oak.

It uses steel wool and vinegar to make a dye that reacts with the tannins in the oak. What's unique about this method is a pretreatment with a tannic acid "tea" to make the dye react much more uniformly.

All grain raising (with water) and final sanding (with 220) should be done before doing the staining.

Topcoat as desired, but I'm a big fan of the catalyzed water borne polyurethanes: clearer, harder, longer wearing and notably, faster drying. Faster drying means fewer included blemishes (dust, gnats, etc).


I did my living room floor last year. Pulled up the nasty carpet where I found thick white paint all over these beautiful hardwoods. I learned everything I did on you tube and I was at Home Depot almost everyday. My floor turned out AMAZING! Im now as we speak doing my bedroom, and redoing my hallway. Be careful sanding because the stain will look horrible if there are uneven places. I sanded all the way down to the raw wood. This time I did not because they rented me the wrong sander. My stain color is Special Walnut 224. I washed the floor with soap & water after finishing up the last sanding last night and Im now fixing to put on the pre-stain conditioner. I would not skip that step. The staining is very stressful! But if you know you didn't skip a step you will get through it. Wish me luck and good luck to you!
