ᐅ Install drywall over an existing wall to create a flush, even surface?

Good morning,

We will be moving soon. In our old apartment, we put up a lot of wallpaper. I don’t need to explain what that means: removing old wallpaper, filling, sanding, then a painter applies new wallpaper. We took this apartment over without renovation, so when we move out, we will probably just leave the wallpaper as is.

In the new apartment it would be the same process, but instead of removing wallpaper when moving out, we would just apply new textured wallpaper (woodchip wallpaper) on top as a replacement. Since I will be heavily pregnant at the time of the move and simply won’t be able to handle the physical effort, and because the financial cost is always quite high, I am looking for an alternative. Please don’t say “just don’t use wallpaper.”

I had this idea in my amateur mind: a wooden substructure fixed to the existing wall, then interior construction boards or something like Fermacell mounted on that, and after filling the joints, wallpaper applied on top. But I know that definitely won’t work as is, or that I probably forgot to consider something, or maybe there’s a simpler way, or there might not be enough air circulation behind it... So I really need input and advice from professionals!

How can you quickly get a smooth wall over woodchip wallpaper that can be removed again later?

Thanks for constructive answers!

Okay, that sounds reasonable, but also not quite.
They don’t necessarily use insulation here, and it doesn’t seem to cause any issues. How can companies bring something like that to the market if there are moisture problems? I just don’t get it.

Hello,

Not everything that is sold actually makes sense.

You need to consider the exterior wall component as a whole, understand the building physics involved, and then plan the wall construction accordingly. Unfortunately, this also includes an interior cladding with wood or something similar. It might work well, but it’s not guaranteed.

I have seen too many exterior walls clad on the inside that were completely covered with mold. That’s not a good situation.

Best regards

Hello,

I’m a bit surprised. Does this mean that such companies would rather risk many dissatisfied customers with moldy walls because they didn’t consider the moisture problem?

Could it be that they coated their panels with something? Like the idea that if no moisture can penetrate, then none can get into the cavity?

@Lutecia: “Because, as you said, the tiles are glued directly onto the other tiles, so there is no gap where humidity can accumulate???”

So, does that mean I won’t have the problem if I install my panels directly onto the wall?

Have a nice day

Oh right, I forgot to mention, we are still not talking about exterior walls, the ones with the windows in them.

Hello,

I still don’t quite understand the purpose of your approach.

You want to avoid wallpapering only the interior walls, but you’re okay with doing it on the exterior walls.

Then you plan to cover the interior walls with some kind of clip system on a substructure (which certainly won’t be cheap) or with a drywall system so you can remove it again when you move out.

Regarding the interior walls, I wouldn’t have too many building physics concerns.

Best regards
