Hello everyone,
About 2-3 months ago, we had wallpaper installed in our new build. We did the priming and painting ourselves.
About a week ago, we noticed that in many rooms on the attic and first floor there is a horizontal wrinkle several meters long in the wallpaper. The wallpapering was done with glass fleece. In my opinion, the wrinkle appeared several weeks after the wallpaper was applied.
Could the wrinkle be related to higher temperatures inside the house? We are not living there yet, and some of the roller shutters were not electrically connected, so in the last two weeks, there was strong sunlight and high temperatures.
Could the plaster have contracted due to the temperatures? Or could the new build have settled slightly because of the temperatures, causing the wrinkle?
What’s strange is that the wrinkle is about at the same height in all affected rooms. The exterior walls were built with calcium silicate bricks.
At first, we feared that horizontal cracks might have appeared throughout the house, but I opened the wrinkle at one small spot and did not find any crack.
Does anyone have an idea what might cause this wrinkle? Could it indicate a serious problem?
Thanks and best regards.

A few additional notes:
1. The wrinkle only appears on the wallpaper on the exterior walls. It does not occur on the interior walls (drywall), where there is naturally no plaster.
2. So far, we have not noticed any wrinkles on the ground floor. However, they are present in many rooms on the attic and first floor, always at the same height.
3. The shell construction was completed over a year ago, so it has already gone through one summer and one winter.

Report the defect and have your construction company inspect it.

Does anyone have an idea what the fold could be? Could it indicate a serious problem? Cracks in the plaster or, in the worst case, in the masonry. Serious problem? The crystal ball says: maybe yes, maybe no. If you check or have it checked, we’ll know more.
Thank you for the feedback.
The developer is now insolvent, so there is nothing that can be done from their side.
By checking, do you mean simply cutting the wallpaper along the fold or removing the entire strip? Or the whole wall?
We tried it on a smaller area along the fold, and no crack was visible there. So should we open up a larger area?

Those will be cracks in the plaster, large enough that the wallpaper can no longer hide them.
Or compression caused by settling or shrinkage of a joint. The only solution is to check it out.Similar topics
