ᐅ Heat the screed in the shower area immediately after installation.

PäddaHello.
The screed has already been laid throughout the entire house, except for the shower areas in the bathrooms. It would be better if the tiler handled those.
The screed used in the house was a fast-drying type and has been ready for covering for 10 days according to moisture measurements by the screed installer. The functional heating and readiness heating have been properly documented by the plumber.
Due to construction delays, screed could only be installed in the shower areas yesterday, at least on the ground floor. Now the screed is in place in the ground floor bathroom’s shower area. This is Quick-Mix B03 screed/concrete, according to the packaging. The tiler said that the heating can already be running at a 25°C (77°F) flow temperature while the screed is being installed. However, I read online that screed should always rest for several days before gradually raising the flow temperature, so my understanding is that the heating should be completely off.
I am a bit unsure what to do or whether I should just let the tiler proceed.
Another question is after how many days the heating flow temperature should be increased. The tiler said he would inform me at the appropriate time. He also wants to start with the wall tiles in two days. For the screed laid previously throughout the house, I received a heating protocol with corresponding temperature values and days, which was loaded into the heating system and followed accordingly.
Could you share your opinions on this?

Vicky Pedia2 Jan 2021 11:29Hello, as a general rule, the screed should rest for one week after installation (at least 5 days if necessary). At current temperatures, the supply temperature can safely be around 20 degrees Celsius (68°F) – I consider 25 degrees Celsius (77°F) too warm – assuming the room is heated. There must be no drafts, and the temperature difference between the supply temperature and the indoor temperature should not exceed 10 to 12 degrees Celsius (18 to 22°F). Then it should work without risk.
