Expensive but damn good!

During the renovation of our bedroom, I came again to our permantentes building physics thermal bridges issue in a bottom corner of the room. During the winter months the interior wall has a temperature of about 15 ° C, which inevitably leads that there reflected condensate in freezing temperatures. White Horse "every year" is inevitable and is fed beautifully by woodchip, wallpaper and wallpaper paste.

I have now solved the mold problem after many years, finally as follows:
I have the old wallpaper and paint removed and the new wallpaper-papered zoom only up to the problem location. The wall piece in the entire problem area so I have left naked and this 3x only with the space fritz F10 color painted.
In order to take any chances, I have the color not tinted, but left pure.
Although the corner of the room in the floor area is half a meter white - but now absolutely free of mold.

For me, this is a good compromise, since I can not re-build the apartment house.
The great "Ventilation Tips from experts" are always merely theoretical.

The room fritz-color contrast, simply provides the mold a breeding ground. The wall can "breathe" and as soon as possible to dry again. Since wallpaper, paste and co. the molds are offered no further action sites are missing, provide.

It is a pity that you can not buy as smaller containers that color. 2 liters could easily have passed.
But the main thing, the annoying mold is finally gone!
