ᐅ Construction dehumidifiers – a must-have?

Hello,

In our case, fast-setting binder was used (free of charge). The downside for us: the screed has settled – and that after 1 year. As a result, the baseboards are hanging up to 1cm (0.4 inches) above the floor. I’m not sure if this would have happened with a normal screed.

This is initially normal, which is why you will find in all construction descriptions the note that silicone joints are the responsibility of the homeowner for maintenance and therefore not covered by the supplier’s warranty. For this reason, we, for example, advise installing baseboards – if desired – only later.

From my observation, using a fast-setting binder not only makes the screed dry faster but also causes it to settle more overall. Since all of this still occurs within tolerance limits, as a homeowner, you have to accept it.

This illustrates once again – even if only on a small aspect of the construction work – that builders from previous years, who took significantly longer to complete projects, in my opinion, should not be considered “outdated.” In today’s fast-paced world – where houses are ideally ready to move into yesterday – there are quite a few consequences caused by this “rush-rush” approach.

@Bauexperte: Then we are lucky. In our case, the builder immediately repairs the silicone joints in the wet areas (and continues to do so for the first 5 years). We outsourced everything except the tiling, and we were also unaware of the settling of the screed. That’s why there are gaps everywhere now that no one wants to fix.

Hello
The screed has been in place for three weeks as of Wednesday – but there are still many dark spots.
Hopefully, the utility providers will lay the pipes inside today, or at the latest tomorrow, so the heating technician can install the system this week and start the heating process.
At 6°C (43°F) indoor temperature, drying won’t happen without heating.
Regards
Chris

Since last Wednesday, we have had two electric fan heaters in the house – one in the dining room and one in the upstairs bathroom.

This has not only made the house feel cozy and warm, but also very humid – like a Turkish steam bath. However, over the past few days, it seems the humidity has decreased a bit. At the end of last week, the painters were also here, plastering our walls.

You can clearly see how the heaters are drawing moisture out of the floor. Although this uses a lot of temporary construction power, otherwise the screed probably wouldn’t dry as quickly.

We also hope that the utility company will come this week to install the pipes. They currently have too much work on their hands.

Although this uses a lot of construction electricity, otherwise we probably wouldn’t be able to dry the screed so quickly.

Hello, now I have a question about a point that I don’t quite understand here: It is quite commonly stated that ventilating the house when it’s cold and humid outside doesn’t help. I want to phrase this carefully as a question: Cold and low RELATIVE humidity is ideal, right? -> I bring dry air into the house through ventilation, heat it with geothermal heating, which allows this air to absorb significantly more moisture, and thus remove a good amount of humidity from the house each time I ventilate. Of course, the effect should be much lower in foggy weather outside, but it should not be zero. Or am I completely mistaken? What do the experts think? Regards, Augustus P.S. How can I create a proper line break here? It’s hardly readable.

I do believe that daily rapid ventilation is effective. I can definitely notice that moisture is released this way. I ventilate twice a day for about 10 minutes each time.

However, we have been quite lucky with the weather in recent days; fog and humidity have been limited.
