Hi,
We have parquet and cement screed and didn’t need any leveling compound. The screed person has to put in a bit more effort. And expansion joints with the tiles? How large are your rooms?
Much more important is: Anhydrite screed is very sensitive to moisture. We had a massive water damage in the house due to a burst pipe. And luckily cement screed, you can get it dry again. With anhydrite screed, we would have had to tear out the screed throughout the entire upper floor. In other words, the house would have been completely uninhabitable for months.
After that experience, I would never take anything other than cement screed...
Best regards,
Andreas
