My 15 year old dog urinated on my hard wood floor and now it is kind of bumpy in that spot. How can I fix this? I have read that I cannot sand it because it is thinner than the older hardwood floors. My house is only two years old, so my floor is pretty new. I am hoping that I will not have to replace that plank. That seems like a lot of trouble and work. Thanks!

If you have the new laminate flooring there is no way of repairing the issue of too much liquid in one spot. The laminate has raised away from what it is glued to. You will have to replace that one plank and avoid too much moisture anywhere on that floor or the same problem will occur.

I am doing away with my laminate flooring. Cleaners used too much water when washing, so a lot of my floor looks like your one spot. Just a damp mop is good enough to clean that type of flooring.

If it is real wood, you should be able to scrape and sand down a "bump". Use 220 grit and then 320. Get some Minwax or other similar colored stain, wipe it on and then blend it in. Finish with polyurethane of the same gloss as the floor. Let us know how it looks.

The question is whether the floor is solid wood, engineered wood, or laminate flooring. If it is laminate, then as mentioned, you are SOL. If it is engineered and the top wear layer has a thick enough layer, you may be able to sand it flat and apply stain and finish to match the existing. If it is solid wood then you will definitely have enough wear layer being only 2 years old. You will have to use something more aggressive than 220 to level the bumps. Wood is hygroscopic and moisture causes the cell structure of wood to expand and that is why it feels bumpy. I would use an 80 grit piece of sandpaper to smooth it, followed by a 100 to remove the 80 grit marks. Then stain it and finish it. One coat of stain and two coats of finish minimum. Do not expect the color or sheen to match exactly, especially at first, but as time and UV rays affect it, it will look better.
