Hello everyone,
our cement screed was heated up in 5°C increments from 25°C to 50°C. The 50°C has now been maintained for 12 days, although it did not always reach 50°C. The craftsmen ventilated more frequently, and since the floor cooled more as a result, it was difficult to maintain the 50°C. Of course, there was still moisture in the screed at the beginning.
Our flow temperature should be a maximum of 35°C, so 50°C should be fine. However, I now have the following questions:
1. Does it have negative effects if the temperature fluctuated between 48°C and 50°C during heating?
2. Someone told me that the temperature of the screed during heating should exceed the flow temperature. In other words, since our flow temperature is 35°C, the screed should also reach 35°C during heating. Is that true? Because I am not sure if that was achieved. Maybe during 1-2 nights, but during the day the screed temperature was 31-33°C due to ventilation.
Best regards
