Hello,
we had the screed installed on Monday. Now the question is how to properly dry the screed through ventilation. It is cement screed, about 6 cm (2.4 inches) thick and covers an area of 160 m² (1,722 sq ft). The heating system is expected to be connected only next week. Until then, should we ventilate briefly from time to time or keep everything closed? I have heard several times that once the heating is running, the best method is to have the heating on and the windows tilted open. Is that the best approach? Or is it better to have the heating on with windows closed and then ventilate the whole house briefly and frequently?
Thanks in advance

In the past, screed was installed in autumn and left to dry throughout the whole winter without windows, which is still the best method. This means the windows should be kept fully open; you don’t need to ventilate briefly by opening them only for a moment. Of course, this only works if you are not living inside. If the heating is on, you should use it but not set it to the highest level, as the screed must not dry too quickly. In this case, it also makes sense to ventilate by fully opening the windows several times a day.
Tilted windows are ineffective; they only cool down the window reveals, causing moisture to settle into the masonry, which can lead to mold in the worst case. So always keep the windows fully open, never tilted.
