From when can a screed no longer cup?

Hi KlaRa,

thanks for the hint! Something like "too fast is not good either" was something I had already thought quietly to myself.

The other dryers are also not supposed to be used in the basement, but one on the ground floor and one on the upper floor, and only if the weather changes. Currently, we have completely dry weather here for 4 weeks, but that will surely change again. And if it becomes humid outside, I will then turn on the dryers inside.

Is there a rule of thumb for the humidity level to aim for when drying screed and which should not be fallen below? So not below 60%, or not below 40%?

Best regards,

Andreas

Hi,
just some feedback. Since last week, the drying program of the heating system is finished on our side, I kept the construction dryers running a bit longer but since last Friday almost nothing is coming out anymore. The humidity in the house stabilizes at 35-50% with the heating running lightly (about 22 °C in the house).
And today the tilers measured, I don't have the result yet, but it must have been at 2% or below, because they already started laying the tiles!

So it worked well!

Best regards,

Andreas
