Parquet in new constructions and more and more questions

Hello "Pound".
Parquet is not just parquet. If we are talking about a multi-layer parquet (previously called finished parquet), then the wood wear layer can be sanded at least once, but usually up to three times.
The number of possible or necessary sanding procedures depends on the extent and depth of the scratches.
Typically, multi-layer parquet will be sanded after 10 - 13 years of normal residential use. With intensive use, after 8 years.
I have never experienced a "Pattina" on wood/wood materials. However, the term is sometimes misused and used for a "usage- and age-related surface change." That means much and says nothing, admittedly.
Which floor covering you lay where is a question of personal taste and the amount you want to invest.
For purely practical reasons, cork flooring would be a good choice for areas where you want foot warmth, multi-layer parquet for a study (chair wheels must have soft wheels!!) and for a fitness room either parquet or a rubber covering (synthetic rubber flooring).
If a dumbbell accidentally falls on the floor there, a rubber covering glued to the subfloor "laughs" about it.
No one laughs with parquet, though.....

Hello, thanks for the quick response

Yes, it is about multi-layer parquet. None of the mentioned rooms have underfloor heating, accordingly, I prefer a floating installation, and I was thinking of cork as the subfloor.

Parquet is not just parquet. If we are talking about multi-layer parquet (formerly called engineered parquet), then the wood wear layer can be sanded at least once, but usually up to 3 times.

even with "only" 2.5mm?

I have never experienced a "patina" on wood/wood-based materials.

Yes, the "patina" was, I believe, just a term for wear; people like to put things in a nicer light, so I included it in the question.

My concern is that the floor does not look "dirty/worn" after 2-3 years. For so much money, I want a high-quality floor that looks good for a long time (of course, assuming proper care and careful treatment), but from some posts, one might think parquet has to be handled with kid gloves and still doesn't look good for long.

I am torn between laminate and parquet, and I do not want to regret my decision in the end.

A floor covering will never look "dirty/worn" with appropriate (regular) maintenance cleaning! Who could judge this better than an expert designated for this specialized field? Every multi-layer parquet can be sanded down, which is why the minimum thickness of the wear layer was raised from 2.0 to 2.5 mm about 10 years ago. When sanding, a material removal of between 0.5 and 1 mm is to be expected, so you can sand at least once without exposing the core layer. Parquet does not have to be treated with kid gloves, but some things must be considered. The indoor climate is important, which the builder must always "keep an eye on." Air that is too dry (below 40% relative humidity) should not prevail permanently. Also, you should avoid edge beveling; although it looks good at first, contact dirt accumulates here and the bevel disappears after the first sanding. Otherwise, a wooden floor is quite rustic. On one point I must give praise: You first consider what fits—and save yourself disappointment later. However, in my experience, this would not be avoidable if you were to resort to a laminate floor... First take a look at cork. There are numerous surfaces, from "lively" to "boring" (my definition, sorry) and various material thicknesses. For little money, you naturally get little. A logic that should be obvious. And if cork, then no dyed or whitewashed surface. ---------------- KlaRa

Okay, wonderful, that’s enough, I don’t want to make a life’s work out of the floor (so far), if it can withstand a one-time renovation after 10-12 years and last until the next renovation again, I would be completely satisfied.

And dry air (less than 40% relative humidity) should not prevail permanently.

That should be doable, a hygrometer and an automatic humidifier are available.

I hadn’t really considered cork, or quickly dismissed it, because I know two experience reports from people who had/have cork in their homes. In one case, the cork faded completely in the sunlight, in the other, permanent impressions formed in the area of the furniture.

Those were the reasons for me not to think further about cork.

Today I’m going to a large showroom nearby, where I will take a closer look at cork.
