I have a quick question about moisture in the house after screed or interior plaster.
Our house is currently sealed. Doors and windows are installed, the exterior insulation and finish system (EIFS) including the exterior plaster is applied, and the roof is covered. Only the insulation and cladding between the upper floor and the covered roof are still missing. The heating system is also not yet installed.
Last week, the interior plaster was completed. As a result, the moisture level inside the house is currently very high. The current weather (rain and high humidity) makes reducing the moisture by ventilation difficult. According to the general contractor, we should arrange for construction drying (hire a company or similar). However, since the screed is scheduled to be installed in the house in about two weeks, provided the weather allows, they said we can organize the construction drying afterward. Otherwise, it would have to be set up, taken down, and then set up again.
Should I be concerned that the rafters might start to mold or rot because the moisture from the plaster can’t be addressed for about three weeks? After all, the rafters are fully exposed and could theoretically be exposed to condensation if it forms there… Or does this simply just delay the overall drying time?
I would appreciate any answers.
Best regards

Thanks for the feedback.
So I don’t have to expect mold to form immediately within three weeks in an unheated house because of the interior plaster? After the screed, drying of the building will be arranged, or the heating system will be installed shortly after, so that consistent heating and ventilation can be maintained.

Yes, you definitely need to expect that. Unfortunately, we had several wooden windows damaged because we were under the false impression that airing out the house three times a day was sufficient.
Depending on the weather conditions, that is not enough. However, the amount of moisture from the interior plaster is much less compared to the screed. The heating-up process drives so much moisture into the building that it runs down from every corner.
My recommendation for this time of year: not only after screeding but also immediately after the interior plastering, rent three professional-grade drying machines and run them at full capacity throughout the entire space.
I would never cut costs on this. My damaged windows will annoy me for a lifetime!
