ᐅ Lime plaster and lime paint, or something else – new construction

Hello,

In the new condominium, there is still relatively free choice regarding plaster and wall paint.

On the internet, you often read that lime plaster and lime paint are the more ecological options. However, since the developer wants a price equivalent to that of a new car according to the offer, I’m naturally wondering if it makes sense.

The problem is: this is a new build. Energy Saving Regulation 2014 with heat recovery system. Unfortunately, we have a slight history of mold-related issues... including needing to change wallpapers. Our current apartment is a renovated building from the 1960s. Despite ventilating multiple times, there is a cold spot on an external wall where moisture always accumulates, as well as at the window edge.

Since in the new apartment we will also be cooking, showering, washing, and drying clothes inside, we are naturally concerned that too much moisture in the air will lead to mold growth with standard plaster as well...

So, what to do? Use regular plaster and simply apply lime paint on top? Or rely on the heat recovery system to transport all the moisture away?

The bathroom will be tiled up to the ceiling. The ceiling will be covered with either wallpaper with a raised pattern or painter’s fleece with lime paint.

Please help. Thank you.

We also have a Pluggit Avent. As mentioned here before, you won’t have any issues with excessive humidity. However, in winter the air can become too dry. In our case, it dropped to 35% this past winter.

With a controlled residential ventilation system with enthalpy recovery, this wouldn’t happen, but it’s not absolutely necessary. For the few problematic weeks a year when the air is too dry, it’s easy to take measures. Cooking or drying laundry usually suffices. Plants are said to help as well.

Do you have the P190 model or a larger one?
How many square meters (square feet) and people?
Has your electricity consumption increased significantly because of it?

And what is the advantage of a controlled residential ventilation system with enthalpy recovery?

We have the PLUGGIT Avent P310.
160 m² (1722 sq ft) living space, with 2 people. The system runs on level 1 out of 4.

You can’t really notice any change in power consumption whether the controlled mechanical ventilation is on or off. I estimate the consumption to be around 1-2 kWh per day.

With enthalpy recovery: moisture is recaptured, so the air doesn’t get too dry.

Why did you decide against one with enthalpy?

Well, to be honest, we didn’t research thoroughly. Our heating specialist always installs Pluggit, and some friends have also had good experiences with it. But we are very satisfied with the system. For us, the controlled residential ventilation is a huge improvement compared to our previous rental apartment, where we had moisture problems despite airing the rooms 3-4 times a day.
