Topic tags/keywords: hardwood stains floor sanding paint

I have been working on my new house. The floors were painted black, very poorly. After sanding for several hours I think I found the reason why the previous owners painted it black. There are a lot of very dark stains in the hardwood floors. I went over the floor with a random orbit sander and a dremel floor sander. I stared with 28 grit, then 36, 60, 80, and 100. The stains would not come out.

I was wondering if anyone had any suggestions for removing these stains. I wanted to put on just a hardwood finish and keep the light color of the wood with out any polish or stains. Is that going to be something I can do or because of these stains am I going to have to use a dark wood polish?

Here are some photos.

To remove dark stains on hardwood floors you need to take it a step past just removing the stain with a cleaner. You will actually have to resurface that area of the floor. To start this process you will need a sander and new sealant. The sealant is usually urethane. If you have an old floor, you may wish to refinish the entire floor to remove all the stains.

Try cleaning the areas with wood bleach (oxalic acid)

I agree with the above poster…try the wood bleach first. If it does indeed work, then you’ve save a lot of extra effort. Good Luck!

I might suggest, if the wood doesn’t come out looking ‘perfect’ after bleaching, go and paint a design, like an area rug might be used. Patterns are good for this if your room can deals with it. I have also seen it done on concrete and it can look great.

Different type of area rugs are available in market which is cheaper than hardwood flooring, I would prefer you to visit Natural Area Rugs where you can get jute rugs, sisal rugs or anti fatigue comfort mats etc.

I have never used the wood acid. I have refinished a number of hard wood floors that have the branding identified. How does the wood acid work on those areas not stained? I remember I had a number of stains that were like a poke a dot pattern. If you get some of the bleach on the non-stained area’s does it turn or bleach those areas not stained an even brighter or lighter hue?

I’ve tried the wood bleach several times on different things. It one of those “Hope for the best and expect the worst” deals. Sometimes it works and sometimes nothing happens. As for the areas around the stain, yes it will lighten those too. I try to dab the bleach onto the dark areas and keep as much off of the lighter wood as possible. It’s never a perfect fix but can get the areas closer together as far as color and shade.

Very sad, even I faced such situation in my living room. Later on I came to know that because of pet urine, the black spots occurred which was not cleaned immediately. I searched a lot in internet and didn’t found any possible solutions. My friend asked me to contact http://www.pcwoodfloors.com/ the best hardwood flooring site where they have skilled workers for guidance, fixing and delivery as soon as possible. They have the technique to clean the wooden floors and give them a new and freshly look once again.
