Plastered walls not drying yet

[TheOpalFox]

I have had my walls plastered and they are still not cocompletely dry a week later. Do they take longer to dry sometimes please ? Thankyou

No as far as im aware. What's the weather like where you live ? Unless the plasterer used too much water in the mix, but then you'd expect sagging. Is is wet wet or just damp to touch?

Just a bit damp too touch

Strangely my parents just had this and had to delay their decorator by a few days. It did dry eventually. We’ve had a lot of rain where we are so probably because of that.
Keep your windows and doors open as much as you can and maybe you could borrow a dehumidifier?

Skimmed or fully plastered? That's not unusual. Don't use a dehumidifier, you risk cracking it. Continue to allow it to dry naturally.
