ᐅ Restricting access to the screed due to residual moisture

Hello,

9 weeks ago, our heated screed was installed (without additives). A CM measurement about 10 days ago showed a residual moisture content of 2.5%, and today’s new measurement is 2.4%.

To stay on schedule, it would be possible to "seal" the screed.

What is your opinion on this?

Best regards, Barossi

But how does the drying of the screed work most effectively?

The most important thing is heating, and depending on the humidity in the room, ventilate or use a construction dryer.

A construction dryer never hurts; we had a device running until the very end. Before moving in, the relative humidity in our building dropped to an uncomfortable 30%, sometimes even 28%, so there is probably no residual moisture left in the building.

Hello,

It’s really frustrating!

Today, the moisture content in the screed was measured again. It hasn’t dropped and is still around 2.3 to 2.4 on average, exactly the same as a week ago.

Over the past week, I had all the heating systems turned up fully, the plumber ran the Zehnder 450 ventilation system at maximum capacity, and I also set up two very large construction dryers. The room temperature is around 30°C (86°F) with 25% relative humidity.

If possible (and if it makes sense), we ventilate 2-3 times a day.

...but the damn screed just won’t dry...

What should we do?

Best regards, Barossi
