ᐅ Screed Drying – Incorrect Drying Program Set

We realized after 12 days that our installer had set the wrong drying program. It has been running constantly at 30 degrees Celsius (86°F) for 12 days. This is an electrically powered external device, not the heat pump.
The installer is coming tomorrow. What do you recommend? I will have the screed moisture measured today. However, my main concern is the expansion. If I increase the temperature from 30 to 40 degrees Celsius (86 to 104°F) tomorrow, then from Friday to Saturday to 50 degrees Celsius (122°F), and keep it there for two days until Monday, will that be sufficient?
We have already scheduled all subsequent work steps with all contractors after the drying program. It would be a disaster if we had to extend the program.

Contrary to the widely held belief about "dry heating," this is actually a so-called functional heating process. Its purpose is to verify the heating system’s function and to heat the screed without causing stress. After this process, the screed can still be "wet." Functional heating (usually 21 days) is a preset heating program that includes warming up, maintaining temperature, and cooling down. I strongly advise against manually increasing the temperature in 10-degree increments!!!!! It might work, but most likely the screed will cup, meaning the edges will rise, similar to a slice of bread drying on a table.

Conclusion: choose the correct program and run it again.

Can the temperature then alternatively be increased by 5 degrees every 12 hours? We had the screed measured. It has reached just under 2 percent. After 12 days of drying, the function of the heating circuit is thus proven (functional heating), and the purpose of the surface heating during drying is completed with the drying, right? Only the 50 degrees were not reached. What impact could this have? The heat pump will later only heat up to a maximum of 35 degrees anyway.

You are asking if it is allowed to go a little faster than permitted! Please, again, this has nothing to do with drying!!!!!!!! If you increase the heating in 5°C (9°F) increments, okay, maintain for at least 4 days maximum, then reduce again. Man, the answer is difficult. There are guidelines and you are asking if it can be done differently. Give it a try and good luck!
