ᐅ Drying with a construction dehumidifier

Hello,

The screed has been in place for one week, and the underfloor heating has now been turned on to help with drying. Dehumidifiers are also being used. Mineral insulation was installed, and both the exterior and interior have been plastered.

Now we are worried that it might be drying too quickly. Is this common practice? We want to avoid any risk of mold.

Thank you

Hello

Sorry, the dehumidifier is not in use. It is planned to be put into operation.

As far as I know, that is much too early. Recently, we've discussed quite a bit about screed drying here.
It should dry naturally with intensive ventilation for two weeks, then further measures can be taken.

Why mold? The risk is that the screed cracks or warps due to improper drying.
If dried incorrectly, it can happen that the screed doesn’t dry from the inside at all because the surface no longer allows moisture to escape, preventing evaporation from bottom to top. This probably won’t be an issue for you since your heating is from below. Still... I’m just an amateur.
It also depends on the screed itself—whether it’s concrete or something else with additives...

Hello

and the same applies to interior plastering, so we don’t have to worry about that? As mentioned, the construction dryer will, if at all, be used later....

In my opinion, yes, you should have concerns... but nobody seems to understand me here today (or I’m missing something 😉), so hopefully other comments will help 😀

Why should a construction dryer be used at all? Usually, the screed drying phase of the underfloor heating system is sufficient. Besides, the weather outside is currently very nice. I would not use a construction dryer.
