Good evening,

a quick question:

Is it possible to have the exterior plaster applied before the interior plaster?
We had the roof truss installed today, the windows will be delivered at the end of the week.

I would now like to have the exterior plaster applied so that the scaffolding can be dismantled afterwards (of course only if the roofer is finished by then).

The interior work will still take some time, as the plumbing company is on vacation.

To keep the costs for the scaffolding as low as possible (about €120 per week), this is our idea.

On the internet, I only found that in the past, the interior plaster was applied first, then the exterior, so that the moisture can escape better. However, nowadays, the interior plaster can dry better through proper ventilation.

We used Poroton bricks 36.5 cm.

Thank you all

It's definitely doable. As long as you already have all the electrical and water installations you will need later in the exterior walls (Außenwasserhahn!). And if you have gas, the necessary emergency valve (or whatever?) should also be installed beforehand. Oh yes, don't forget the windowsills.

Hello,
That could be possible! How dry are the exterior walls? Prefer to let them dry?
After interior plastering and screed installation, I would use a few construction dryers in addition to regular ventilation.
Best regards

We received the exterior plaster already in May. The screed and the interior plaster followed four weeks later at the beginning of June. The windows were installed. Then the construction stood still for a full six weeks. Just air and patience. No dryers. It was picked up again at the end of July, and I think the house is really nicely dry. Cardboard, for example, no longer gets damp when it is inside the house. It just takes some patience and good ventilation. Karsten

Thanks, I wanted to order the window sills today and then have them installed. I will also clarify the electrical and water connections today.



Since they are Poroton bricks, they are actually quite dry (as long as it’s not raining. Because they then soak up quite a lot of water).



Thanks, Karsten, that’s roughly how we wanted to do it as well. After the interior plaster, did you ventilate inside from time to time or basically leave the windows open all day?
