Hello,
we are building a semi-detached house with a developer.
We have to do the painting work ourselves afterward
(we can no longer afford a professional painter).
We only imagined plastered walls
(which we find visually appealing).
Either just filling until the surface is smooth (e.g., Q3 level) and then painting the wall, or applying textured paint or roll-on render over the filled surface.
The developer has now expressed concerns and told us that in new builds there can be a very large number of small cracks.
We are building brick by brick with sand-lime brick (or rather, the developer is) and some walls are gypsum concrete, but about 90% are sand-lime brick.
How are your walls in new builds with only plastered surfaces, especially with sand-lime brick?
Some acquaintances who built with Ytong have so far only had minor cracks after 1.5 years (but only at the top of the wall, at the connection to the ceiling, with large cracks).
But not like the developer said, that there would be small cracks everywhere.
The developer recommends using painting fleece so that the cracks remain under the fleece.
I know that cracks can occur in new walls during the drying process, but we only know of occasional larger cracks, not many small or medium cracks everywhere.
I hope you can help me.

If you want to wallpaper over it, you should at least sand it down a bit.But he doesn’t want to do that. Pwnage619 schrieb:
Alternative: textured roller plaster (easy to apply and covers a lot) or brush-on plaster.A few days ago, there was a thread about brush-on plaster in a townhouse stairwell. I took a closer look at the textured roller plaster. So: it’s not what you would typically expect from plaster. It ends up looking like textured wallpaper 🙁P
Pwnage6191 Jul 2022 12:22I never said that I don’t want to sand.
For me, filling holes and sanding is not a problem.
I just want to achieve a good result in the end that will last for years (I understand that occasional small cracks are normal, but they should remain few and not become many or significant).
That’s why I’m asking if filling and sanding is enough, or if it is absolutely necessary to use painter’s fleece in new construction, otherwise the wall will become full of cracks, as the developer said (although he may have greatly exaggerated).
We have sand-lime brick walls and no experience with them.

I never said I didn’t want to sand.No one said that either. You were just advised against it if you don’t plan to wallpaper.

I had the cotton plaster shown to me once No, that was cotton plaster. Roll plaster is something different :-)

However, to my knowledge, he did not upload the photo. Just read it yourself https://www.hausbau-forum.de/threads/rollputz-im-treppenhaus-wie-auftragen.43640/page-2#post-582265

Pwnage6191 Jul 2022 13:57We didn’t like the look of the cotton plaster.
It would be either the traditional roller-applied plaster, or possibly a paint-on plaster such as clay plaster,
or try to smooth the walls and just paint them.
But the question remains whether these options might lead to too many visible cracks.
