Parquet in new constructions and more and more questions

these hamburgers deliver? can be done yeah

real wood floors can probably be laid if laminate is also possible. from 1.5% residual moisture as far as I remember. if you build with a construction company, there will be an official residual moisture measurement of the floor anyway. only when this is good can the tiler start. and then you can ask him if you may also start laying your parquet now. best to request a copy of the measurement report or photograph the barometer during the measurement (then it looks like in the attachment, we had a residual moisture of 1.6%, the sample weighed exactly 50 grams), so that you later have proof of readiness for laying.

Hello "sunny84".
You have already received a reply from "neige".
However, it does not reflect the problems you are certainly facing.
Let’s put it this way:
There are trades that are not suitable for amateurs. And parquet installation by gluing it to the subfloor is one of those trades.
Parquet layers do not learn for 3.5 years without reason, in order to learn during that time the special features of the substrate, the knowledge of how to treat it, how to handle filler, residual moisture - including flatness testing and tooth sizes for base filler.
Advertising admittedly suggests that you can do everything yourself.
If you can ice skate, you will also manage to install parquet.
Jokingly noted here!
The same applies to parquet renovation, which you did not ask about here.
In my professional work, I have had to inspect new residential properties where young couples glued parquet themselves.
To cut a long story short: the workmanship was poor and the parquet had to be removed on 3 floors. Because the use of the areas was not safely possible due to multiple detachments (hollow spots).
So I strongly advise you against the plan to install parquet yourself by full-surface gluing.
Whoever once installed laminate floating cannot necessarily also glue parquet boards on a screed.
The professional knows if, where and how to create a joint with what in the surface if necessary.
Please also consider that as the installer you must know and apply the technical rules of parquet installation.
It does not matter at all whether you are a private person with DIY wishes or a trained parquet layer!
In case of damage later, you will be personally responsible.
There are simply too many "traps" waiting here that you as an amateur cannot know – and that even (so-called experienced) professionals sometimes stumble over.
And that can hurt financially!

As a very well-meant advice from practice for practice: KlaRa

There are trades that are not suitable for laymen. And parquet installation by gluing it to the substrate, this trade belongs to them.

That is nonsense! With proper preparation, time, and love for the work, it works well. At least if you buy prefinished parquet (click connections). Where you buy your parquet, you can also buy all the exactly matching tools. The screed layer man will tell you if the screed is ready for covering. Only if it was not laid properly (e.g., not absolutely level), then you may get problems and might have to use leveling compound to even out the floor.

@ "sunny84": Certainly you will make your own considerations about whether "love for work" can replace the "experience" for a parquet gluing and the previously absolutely necessary subfloor preparation. The contribution by "nordanney," on the other hand, seems to me typical of an opinion when one does not have to take responsibility for the consequences of his public recommendations. Unfortunately, I know this from other forums, and it continues here as well. A screed layerer is by no means – as claimed in the post – responsible for the readiness for laying. According to current standards, the builder alone is responsible for the approval towards the installer. This is due to the fact that there are currently too many special screeds (cement screeds with additives), whose drying behavior cannot be "lumped together." And further: A leveling compound is not used only when there are (however presented) "problems"! Once again, a blanket assertion with nebulous suspected reasoning. It is much more the case that you as the builder, since you are at the same time also the installer, are responsible for the success of your plans and work! Sure, how you later define the success remains up to you, as long as you are not later made life difficult by some internal family opposition because of it. But for the assessment of a subfloor, whether it is ready for installing, the corresponding evaluation knowledge is necessary! And then it continues with the creation of an installable subfloor through priming and smoothing compound. These are not only needed when there are "problems," as was claimed recently. It is rather correct that before gluing (also) parquet, you need an absorbent subfloor. And the knowledge required for such creation cannot be "pulled" from perhaps a two-page brochure from a hardware store. And one should keep a natural caution before well-meaning but possibly rather less helpful advice, for which one (unlike specific recommendations from experts) does not ultimately have to "put one's head on the line" if things go wrong. -------------------- In conclusion to this certainly sufficiently discussed topic: KlaRa

Strangely enough, it works thousands of times in DIY – and often it is carpenters/joiners who lay parquet, so basically also outsiders to the factory woodworking.

I don’t want to question what you, KlaRa, are saying – totally correct for an expert.

Still, you are also dramatizing – maybe on purpose, so that not every fool thinks he can do it, but one shouldn’t perhaps exaggerate so much.

I know my work and I am an amateur - in real life an office worker, but this is about doing it yourself, not about THE perfect job according to DIN, any standards or whatever. Here it is worked pragmatically (which, by the way, many craftsmen also do), and that doesn’t have to be wrong. I speak from several hundred square meters of parquet flooring in various properties and cannot detect any difference from the work of a parquet layer. And yes, I can judge that, since real estate is my job.

Of course, one can be a "scaredy-cat" now and not dare to do it. That is also completely fine, craftsmen must also have their justification. But to categorically exclude that a layman can also do it is presumptuous and arrogant. But if I look at what 250 sqm of parquet flooring in my own house would have cost, I’d rather buy my wife a new car or take the family on vacation for the next three years (unfortunately the savings actually went into the outdoor facilities!).
