Wagner W 14 vs 10 layers wallpaper

In my new apartment the last few decades has been cheated on the renovations as anything. Occasionally was even leveled at the old wallpaper layers over it to obtain a flat surface to gossip about a new wallpaper layer over it.

My first approach was moisten the wall and scrape off with a spatula. It went down to the very first wallpaper even reasonably well. But the first wallpaper was installed about 60 years ago was extremely persistent.
Then I tried it again, only with wallpaper remover. It was the same result. It always took turns only a few layers.

The Wagner W 14 the first wallpaper soaked on the wall, but then so good on that I read once completely replace all wallpapers layers at the point where I had draufgehalten the Dampftapetenablöser.
For that I'd even forgive a 6 star if I could.

Although many wallpapers layers with occasional filler in between were still cumbersome, because only this small area replaced respectively. After half a day I had the whole room wallpaper free.
