5/8" red oak, stained with dog pee.
Oxacylic acid? Bleach?

How old are the stains? That makes a big difference.

Can I stain with spots and blend it in, or will it make the dog pee
just that much darker?

Probably will never get a good match that way. You may be able to come
close (IE: not perfect but less of an eyesore)

Sanding sealer? Never used it. Sounds like a good idea. Is it?

Resanding and refinishing will only work if the stains arent very deep
and you go a fairly dark color.

And for gaps I've heard taking sawdust, mixing with wood glue, putty
knife into gaps. Then sand. Anyone ever try this?

Nope. Doesnt work.

Not a big area, just using my small belt sander (alright, got the Mrs.
doing that) and wondering what to do next....

Hehehe if she's already sanded it, your choices are somewhat limited.

A few questions then I'll come up with best guess since I can't actually
see it (if you can get a picture online it will help)

1) How old is the stain? Is there any odor left?

The pee stains are about 2 years old now. the dog, about 2.5. Odor? Not
that I smell.


2) How big is the stain?

I never wanted the dog in the first place. If and when you get kids,
sometimes the kids win and you don't. In fact, in our household, I'd put
that ration at 80:20. To answer your question, about 25% of the floor
is affected.

A little background might help. The floor, 50 years old, was originally
stapled with vinyl tiles shortly after construction. So, besides the pee
stains I have metal oxide stains. Sorry for not mentioning that.

But where the dog went pee the floor has a certain texture to it, like
where the pee combined with the polyurethane (educated guess) and
produced a rougher, now obviously stained, surface. It is unsightly and
typically covered by a long wool rug.

I took the rug to a laundromat ($5.50 washer, stunk after I removed it,
too) and realized that "now" would be a good time to refinish that floor.


3) What color is the stain in relation to the rest of the wood?

Black. Red Oak is kind of dark. Pee stains are large black circles from
7" diameter to 12" diameter. Oh, that urine made the surface rougher,
did I mention that? Had to be some kind of chemical reaction.



4) Estimated age of the floor and can you find matching replacement pieces?

Actually when I moved in about 9 years ago Home Depot stocked the 3/8"
red oak unfinished wood. I thought that was odd. Same width, too. Odder
yet. This stuff is just top nailed in, not tongue and groove, so
replacing could be an option, however....


5) How important based on location is 'perfect coverage'?

Not very. The runner is going to back down on top of whatever we create.


Also, if you can tell anything at all on how deep the stain seems to be,
that helps. I saw your other message and yes, puppy training with paper
can cause this. Folks just don't realize the floor is getting damaged.
If a recent puppy issue, and not too deep, it's fairly fixable but still
not totally fun.



I'm finished removing the surface to the bare wood and the stains are
clearly visible. 3/8" inch is pretty thin. It might penetrate down to
50% depth, and, that is something that I'm not going to mess with.

I've read the ammonia and then hydrogen peroxide setup. I think that's
my direction. I'm not going to remove the damaged pieces, it would be
way too much work.

I'll re-read the min-wax brochure, and continue to read about bleaching
wood. Right now I'm just trying to get to bare wood and am about 1/2 way
done. Using a little belt sander isn't so bad. A lot of saw dust but
manageable, for the most part.

Thanks for your response.

Mike, please join PETA. They need good people like you.
