Tile installation on fresh screed (fresh-in-fresh method)

In other countries this is common practice, it is even laid directly on the concrete, but the climate in winter is different there.

Google "frisch in frisch sakret" there it is explained.

This is called the thick-bed method, which was used more in the past than today. Nowadays, thin-bed adhesive is used... I can imagine that many no longer consider the former as a craft (in Germany).

By the way, the thread is 7 years old and since apparently has a different problem (too eager tilers), discussion should continue here .
