ᐅ Construction dehumidifiers – a must-have?

Hello,
we are currently building as well. In the next few weeks, the screed will be installed.
Our builder now wants to place three construction dryers in the house for two months afterwards. However, we would prefer to avoid this and get rid of the moisture by ventilating. The builder advises against this.
Can anyone give us advice on whether construction dryers are really necessary or if it is possible to manage the moisture without them?

Thank you in advance for your opinions.
Best regards,

Anhydrite requires even less residual moisture when used with glued parquet flooring, for example!!! Try searching for it online.

My construction manager even told me to allow for 12 weeks because we want to install vinyl flooring in the living and bedrooms. But in the end, precise measurements are probably the only thing that really helps...

8 weeks???!!!!

Oh no. If it takes that long, we really might have a problem with our move...

Who plans such a tight schedule...? And I think the idea that anhydrite screed dries faster is a myth. It already contains more than 50% water at the start.
How do you handle the bathrooms? I assume you won’t be installing laminate flooring there.

We were told that 8 weeks is already optimistic and not very common. My house builder never schedules tile installation earlier than 9-10 weeks after the screed is laid. If you want it faster, you have to order cement screed.

Our timeline states that it usually takes about 5 to 8 weeks after the house is erected until the final inspection, meaning the tiles in the bathrooms are installed.
Our site manager mentioned a total of 8 to 11 weeks. That would work out really well for us.

Of course not. We are using tiles in those areas.

The screed in our house is already nicely dry—at least on the surface. It has been curing for exactly one week today. There is also hardly any moisture noticeable inside the house. Maybe they added an accelerator.

You can’t really judge anything just by looking at the surface... It was dry for us as well... but if you leave a box on the floor overnight, the next day the box on the floor would be damp.

The underlying layers also need to dry, which you can’t see. Later, the tiler will measure the moisture at the marked spots.

However, I find it quite confusing that the air in your house is not humid... the moisture from the screed has to go somewhere, and that would usually be the air... so does that mean your screed isn’t drying???
