ᐅ Drywall Mold?

I sent an email to my architect yesterday but haven’t received a reply yet. I’ll give him until Friday to get back to me so we can find a solution. Otherwise, I will unfortunately have to take legal action. I don’t take mold issues lightly, nor do I accept excuses.

PS: The heating was turned on today. For the first three days, it’s set to 20°C (68°F) supply temperature, then it will be increased to 55°C (131°F) in 5-degree increments.

55 degrees? That high? And why don’t you call the architect if this is so important to you?

I spoke with him on the phone yesterday. His response was to sand it off and spray some kind of mold treatment on it, which I politely declined. I then went to the construction site and removed a panel myself. You can see the result in the pictures. I immediately sent an email to the architect and will give him time until Friday.

The fact is, the panels have to be removed, no ifs or buts.

Regarding the 55 degrees, that’s what’s stated in the heating protocol. I also think 55 degrees Celsius (131°F) is a bit too high.

What kind of heating system are you planning to install, and what supply temperature will it have?

I would call him right after dismantling—after all, you are paying him a lot of money.

Complete underfloor heating system with a standard gas boiler,

well, I preferred to have it in writing; pictures are always better than a phone call

I would be surprised if your heating system runs at 55 degrees Celsius (131 degrees Fahrenheit) flow temperature under design conditions – the screed will definitely not appreciate that.
