Another option for drywall in basement guest room

[Haper_00]

We are in the process of making a guest room in part of the basement. The OBS boards need to be covered now, but drywall does not seem like the best option as the laundry room is nearby and the temperature varies quite a bit. Unsure how it would handle potential moisture. Wallpapering + painting directly on OBS also doesn't seem like a good idea as there is a high chance that the wallpaper will eventually crack. Is there any other smooth solution?

Plaster withstands quite a bit, much better than, for example, wallpaper on OSB!

 

[Paul-Staffanstorp]

Only plaster applies as a base for both paint and wallpaper.

If there is so much moisture, it should be ventilated away. No material works in the long run if the moisture load is too high.

Wallpaper on OSB I don't believe in at all, and you also can't apply filler on it, so if you want it smooth, plasterboard is the way to go. If you're okay with it not being smooth, you can paint it, but it will be nothing other than painted OSB.

Otherwise, the traditional option (before the arrival of drywall) is masonite.

Is it really dry enough in the basement to build in studs and drywall with paper on it?
I would have used steel studs and paperless drywall approved for bathrooms.

polish?

putsa?

That's safest. But then you miss the opportunity for insulation.

If you already have OSB on the walls, then just go ahead with drywall. Nothing gets worse by having drywall on the outside. If you have normal ventilation in the laundry room, there are no problems at all with the drywall, and if you don't, you need to fix the ventilation in the laundry room to avoid long-term damage to other building parts.

If you already have OSB on the walls, just go ahead with gypsum. Nothing gets worse with gypsum on the outside. If you have normal ventilation in the laundry room, there are no problems with the gypsum boards, and if you don't have it, you need to fix the ventilation in the laundry room to avoid long-term damage to other building parts.

But OSB is not entirely optimal if there is moisture.

My point here is that the gypsum is the least of the problems here. If there is moisture from the laundry room, it must be fixed with ventilation anyway, and once that's arranged, neither gypsum nor OSB is a problem.

My point here is that the plasterboard is the least of the problems here. If it's damp from the laundry room, it must be fixed anyway with ventilation, and once that's sorted, neither plasterboard nor OSB is a problem

Sure. But the biggest problem is not moisture from some laundry room but from the floor and walls in a basement.

That's kind of what I thought too. The house was drained a couple of years ago and the room has been empty. We moved here almost a year ago and have not seen anything indicating noticeable moisture. But the house was built in 1954 and no major renovation has been done in the basement.

Measure the moisture content in the wall during times other than these warm months. (Now there will be condensation in all stone constructions, so it's misleading to draw conclusions) If it's dry and nice during the winter, it's probably okay, but otherwise you have to build with consideration to the moisture that comes through the construction. It's possible and doesn't have to cost much extra if the moisture levels are reasonable.
