Hello,
we are currently building as well. In the next few weeks, the screed will be installed.
Our builder now wants to place three construction dryers in the house for two months afterwards. However, we would prefer to avoid this and get rid of the moisture by ventilating. The builder advises against this.
Can anyone give us advice on whether construction dryers are really necessary or if it is possible to manage the moisture without them?
Thank you in advance for your opinions.
Best regards,
steffi23

I’d like to join the discussion here and hope the original poster doesn’t mind.
Yesterday, the screed was poured in our prefabricated timber frame house. Since the screed was applied with a two-week delay, the screed contractor offered to add an accelerator to compensate for the lost time by reducing the drying period. The accelerator used is called "Estrolith Temporex." The acceleration is mainly achieved by using less water in the screed mix, which means less water needs to evaporate during drying.
According to the technical data sheet, heating can begin after 8 days, and the floor covering can be installed 8 days later.
Now the question is: Is this realistic? Does anyone have experience with this or similar fast-setting additives?

Our construction company definitely refused to use accelerators. There was no discussion about it. I actually find that quite telling.
I’ve heard that there might be fundamental drawbacks as well. Maybe cracking? No idea...!

A slight settlement is almost always normal and depends on the screed and especially the subfloor.
In my case, the screed (cement screed throughout) has been in place for almost 5 weeks now. For the past two weeks, I have been using electric fan heaters and running a dehumidifier at the same time (55€ per day, which is quite expensive). The temperature is maintained at 21-22°C (70-72°F) and the humidity level is between 50-55%. Starting next week, I hope to begin the four-week functional heating using the heat pump’s electric heating element. Hopefully, this will allow me to have the floor coverings installed in January.
Without a construction dryer, ventilation would currently be difficult because the outdoor air is very humid.
