Hi, I'm in the process of renovating the kitchen. I wanted to ask about what to use to repair the hole in the wall? It seems to be mortar under the drywall. The plan is to tile the wall once it's restored. I would be very grateful for some help here ☺️ I have bought Knauf Rotband plaster, but now I'm wondering if it's the right choice..? The hole is quite deep.
Thank you so much in advance ☺️

You can easily build 10 cm with gipsbruk, so go ahead with that 
scrape off everything loose and brush away the worst dust, pre-wet a little, and smear it on, scrape off with a stick, you'll probably need to do it twice since it shrinks a bit, otherwise use regular putsbruk in stages.

I saw that the hand gypsum (Rotband) has a drying time of 24 hours but reaches its final strength after 14 days. The question is whether I have to wait 14 days before I can tile directly on the wall and mount bench cabinets, or is it enough for the wall to dry for 24 hours? Or are there any other tips to consider? Other mortar etc.? It's a small section of the wall that needs fixing. Grateful for some guidance.
24h is more than enough, if it's dry, it's dry
Gypsum plaster is a good solution, requiring a bit of finesse to make it straight and neat, and if you're going to tile the wall, you should be very meticulous. However, if the wall is very uneven with many dips in several places, I would almost suggest building a new interior wall on top if you have the space, or alternatively screwing battens to the wall and attaching sheet material to them. It will be difficult to make the tiles look good if the wall is very uneven. Especially if using larger tiles. The advantage of building out is that you could also run electrical wiring in the wall.
