Make a plan for old building insulation - How to proceed?

But I found the product Bauter for that, it even looks better.

Yep. Bauter outside.
But you’re not allowed to look at the official product description…
It then just says “color”… LOL

By the way, it also comes from Poland by chance. Such a thing is also available from the company Isofiretec, founded half a year ago. They also promote the product – without certificates or other downloads.

The bad thing is, I would even wish that these products worked and I just had to paint my house and everything would be fine. And the solution to the energy crisis only fails because Adam can't convince us. Sad. But a "check for yourself" or "watch this meaningless video" just isn't enough anymore nowadays. If you want to sell miracle cures, you have to be able to empirically prove the miracles. So Adam, please a reproducible experiment! And not a statement like "the wall feels warmer."

Oh yes, with Lambda 0.000120 and 0.5mm thickness, the u-value is 2.4, if I apply my basic knowledge.

I would like to revisit the topic if there are still interested parties here. I was suggested a similar product by my business partner (Loft doors and powder coating, so no hocus pocus, whose old schoolmate manufactures this coating in the Czech Republic and distributes it across Europe) when I told him about my damp, uninsulated garage. Since I am open to new and unimaginable things and was anyway traveling in my birth country Poland, I quickly arranged an appointment and, together with my business partner/friend, visited the manufacturing company in Warsaw. What was shown to me there initially borders on a miracle (for ignorant people like me) similar to what Adam described here. I have inserted the datasheet translated into German by me here. For the experts among you, it should be easy to decide whether the data is okay. As I said, I am ignorant regarding the topic and still extremely skeptical, but what I was allowed to see on site left me speechless several times.

A short example:

In the morning, we were on a construction site at the financial authority in Warsaw, where in the basement archive, room by room, the walls were sprayed with this white foam/rubber/Dickmann-like filling paste using a paint spray gun (I was told that this works with less pressure to apply the thicker substance).

Briefly about the data I recorded:
Outside temperature 13 degrees, rainy in the morning
Room temperature of the unfinished, emptied storage room 14 degrees / humidity 100 percent.
Mold on the walls, water stains, stench, etc.
According to the technical manager of the authority, insulation on the outside was not possible because the exterior wall is at the curb on the street and partly under monument protection.

Room temperature of a finished room after four coats on the exterior wall with a total thickness of 2.5m and interior walls with 1mm thickness
20 degrees and humidity at 55%
Completion of the room was about 3 weeks before the visit.
Pleasant air climate, no stench, no stains, and no mold.

All rooms are unheated and not insulated.

I was shocked and still am, but of course still skeptical because what the farmer doesn’t know...

There were some other examples from industry shown to me. Sealing of hot pipes and reduction of room temperature, sealing of some hydrogen containers, and so on.

I know there has been heated discussion here and Poland has been somewhat discredited because this “innovation” supposedly originates there. It wouldn’t be the first time that a Pole comes up with something revolutionary. There are several examples, so please don’t sit too high on the German horse and don’t look down too much on the neighboring countries.

Regarding the patent, I can gladly reveal this secret and don’t understand why Adam left it so vague. According to the manufacturer, it cannot be patented because a patent already exists. Anyone familiar with aluminum die casting and Kukillen furnaces knows the coating very well. According to the statement, it was only modified and reformulated so that it can also be used for construction applications. Some have tried it, and some, driven by greed, misuse it. A company mentioned here uses silicates to make the miracle material work, and what that does in rooms, even I know.

But now to the most important part...
I received a few buckets as a gift and will spend the next few weeks coating my garage with them after a crash course in application and the proper pump, and then document it. Then, it will probably be a matter of waiting.
He doesn’t just sell the stuff outright. It requires a two-day training for about €180 including accommodation.
Doesn't seem like pure money-making and somewhat shows that it is important to him that the applicators know what they are doing so that it works.
I almost don’t doubt that it works somehow, but I am very skeptical about the longevity. The boss gives me a 25-year guarantee on the function of the coating, but this thread probably won’t last that long.

Now I am curious about your opinions on the technical datasheet and my experiences.
I sell samples bottled in 1l resealable bags if anything is left for €8.

What is the building material class according to EN 13501?

I had to google that now.
Burning behavior, right?
In the technical data sheet, it is the CSN ISO 3795, equivalent to DIN 75200 in DE, with exactly 0 mm/min ignites not. Are we talking about the same one?
