Easily seal a wood floor?

I recently moved into a new home. I have a bedroom that has a leftover cat pee smell in the carpet. It is not strong, you can only smell it when you get close to the carpet, so I am hoping it is not in the subfloor or anything.
My question is if I take the carpet up and wash the floor thoroughly, is there an easy "sealer" I can apply to the wood floor to seal any possible odor in the wood? I don't want to sand the floor or anything, just looking for some sort of topcoat. Thanks for any advice.

Pigmented shellac like Zinnser's BIN is the ultimate stain/odor blocking primer, an oil base primer might be sufficient. The main thing is to apply a full fluid coat of the primer to block all the odors. You shouldn't need to scrub the wood prior to applying the primer.

What is the wood? If it's just plywood, you can paint it with an oil based primer but clearly you wouldn't want to do that if it's a finished hardwood.

Is the zinner bin a clear coat? It is a finished hardwood underneath.

Zinnser's BIN is a pigmented shellac primer [white] Since it is hardwood, I'd try to clean it well [there are pet odor products although I don't know much about them] and once clean/dry - sand lightly and apply a fresh coat of oil base poly.

Yep, a new coat of poly and not primer on the hardwood.

As long as the current finish on the wood is intact, I think any general cleaner would be fine as I don't think the urine would have penetrated it.

My concern would be the minor cracks between the pieces of hardwood, hopefully the pet urine didn't get in there.

Yeah, maybe the enzyme products would make a difference in that case. Didn't think of that....

Thanks for the tips. Assuming i give a good clean, then reseal, wouldn't the new poly keep any residual smell sealed in the wood by "filling in the cracks", so to speak?

Theoretically, yes, but assuming you have poly now, there should be at least two or three coats and the cracks exist after that, so....

The wood can expand/contract with heat/humidity changes so there is always the possibility of a crack now or later. The poly will help fill the cracks but no guarantee they will stay filled.
