drjack200030 Jun 2021 20:32Hello everyone,
I hope I am posting in the right place.
We are currently building a semi-detached house with a shed roof. Recently, the interior was plastered, and last week the screed was poured. The windows are tilted open to allow cross ventilation, as instructed by the screed contractor. Today, I noticed stains on the OSB boards. The general contractor says it’s not a problem and will be wiped off after the drying phase. The issue of mold worries me a lot. Have you experienced this? Is wiping it off enough? I would appreciate your experiences.
Thank you
Good luck
Today I also noticed mold on the OSB boards in the attic under the roof

I’m not a mold expert, but I had something similar with drywall in the attic at my place. In my case, it was limited and mostly superficial, only in a few spots.
I got a mold remover, applied it several times, let it sit, and then wiped it off, making sure to ventilate well.
However, if the mold has penetrated deeper, the only solution is to remove and replace the affected material.

Why are they sealing the ceiling without insulation, that’s the question?
When it comes to mold, I would be very cautious. If in doubt, hire an expert to assess the situation. Please don’t rely solely on what the general contractor says, as they often want to avoid extra costs.
Yes, the ceiling will be sealed with a membrane after installing insulation. However, companies do not always work carefully here. Therefore, if the installation is not done properly, moisture can get into the insulation layer later on, condense, and cause the insulation to become saturated.
You need to be extremely vigilant about this! When asked beforehand, I personally always recommend using tongue-and-groove boards so that moisture can escape upwards through the joints if necessary.
