Repairing parquet: Is it wood?

I do not see any deep damage. Color haze usually goes away. Go for it if you basically like wooden floors. The machine rental companies will provide you with the right grit for the first and second sanding. I prefer treatment with oil rather than wax – a matter of taste.

Thank you! In this case, a disc sander should be sufficient, I assume? Otherwise, it is often said that 3-4 sanding passes are needed. K60 and K120 or should I start coarser after all? Should one polish after each application of hardwax oil or not? General instructions often mention it, but the manufacturers (e.g. Saicos) only say to apply twice, let dry, done?!

Sanding is done quickly, creates a lot of dust, and always amazes you anew at how beautiful an old floor can become.

We used a sanding machine for sanding our solid wood floor that "carried a bag" and sucked the dust straight into the bag. :) And you are right, it looked incredibly beautiful afterwards. I would always try to preserve and refurbish solid wood first.

Thank you very much for the answers. In its current condition, I definitely don't like the floor. I will try to work on it and report on the outcome. Certainly effort, but borrowing equipment for one day is still manageable. If it doesn't work, I can always stop and redo it. The idea of the decorative wax also sounds interesting. So I could, for example, brush on decorative wax "Oak". Then, as recommended, another layer of clear hard wax oil. Would that also work without sanding? As mentioned, there are no major damages visible... but if the surface is uneven before painting (partly grayish, partly leaning towards beech) - can I even it out with the decorative wax, or will the differences still show through?

Ultimately, it also depends on what you want to achieve or what you will be satisfied with; sanding also needs to be learned – it can go very quickly and you end up with dents!!! If you then work with colored oil/wax, sanding is dangerous because the floor absorbs the color pigments unevenly. I did something like that many years ago with a professional machine....... the corners etc. according to the expert’s advice with a hand sanding machine. Colorless was great but then....... the unevenly absorbed dark color pigments made it look like after a room fire. In the middle, super nice, but in the spots where I had to use a different machine because of corners, etc., it was a nightmare. Result: I then coated everything with Osmo decorative wax applied/rolled on opaquely, then it didn’t matter and I liked it too. Depending on the situation, I could also imagine that you clean the floor well and then sand it by hand with fine paper. For example, the Osmo hard wax oil can even be applied without sanding. Only if I want to get rid of deep grooves or dents would I use the big sander, because that costs money, time, nerves, and carries the risk for a layman that it goes wrong, not to mention the dust. Idea: Try this simple and inexpensive solution first, and if you don’t like it, you can always do the big machine sanding action. I could imagine that it will look very good. I have always used Osmo for the floors and I like it, also because it is great to work with.

Could it be that you are more disappointed to find parquet than the laminate you had in mind? Well, I would be jumping for joy, which can certainly be read between the lines. Here, it rather reads as stolen enthusiasm.

Certainly not. I am not eager to install a new floor. Otherwise, I could just do it anyway.
I am just a bit lost when it comes to carrying out the repair, because there are so many possibilities and uncertainties.
Maybe I am overthinking it and should just try something. A clear recommendation as I had hoped for does not seem to be emerging here. That was perhaps naive to expect given the many possibilities.
