I have patched the worst damages on the chimney with plaster mix B, but I found it very difficult to work with since I'm not used to plaster mix.
I would like to make the chimney a bit more uniform and also fix smaller nail/screw holes.
Is there any other mix or filler I can use that is easier to work with?
I have a fireplace downstairs and it's on the upper floor that I'm working on fixing the chimney, so it doesn't get very warm where I'm working, barely noticeably warmer when I fire up downstairs.

Seems a bit complicated with primer, strips, etc., but maybe that's what's needed.
Can't you apply it like regular putty and sand it afterwards, or do you use the strips to avoid sanding later?

Now it was done, and it was much easier than the other plaster I used the first time around.
Now the question, when it comes to painting the surface, is whether you need to prime or if it's just to save on paint usage.
From what I understand, it is preferable to use silicate paint, which I already have at home.

Doesn't matter... Pick the color you think looks best. Silicate paint is breathable but if this is an indoor surface, you likely don't have much moisture that needs to be transported back and forth, do you?
Ordinary latex-based wall paint works just as well for this purpose. If you choose this paint, you don't need to prime.
Regardless of your choice of paint, you should wait until the plaster is completely dry before you start painting (but you're probably aware of that...).

The reason I thought one should use silicate paint was that I had it on the plaster walls in the basement and I used regular wall paint on the chimney in the kitchen when it was renovated almost 10 years ago, and there the paint has cracked and bulged outward in the cracks. What could this be due to?
Can I use the same regular paint that I have on the walls? It doesn't mention latex on the can, but I think it's plastic-based, so it's probably the same thing I guess.
How long does gypsum plaster need to dry?

In basements, you often have moisture migration, so you should definitely use silicate paint (or some other diffusion-open paint) there.
I don't know why the paint in the kitchen has cracked? However, I have painted my indoor chimney with latex-based wall paint (commonly known as plastic paint) without any problems. It was Beckers wall paint.
I have never worked with gypsum plaster, but with Putsbruk C in the basement, it took almost a month before it was completely dry (admittedly quite thick layers). It should be on the packaging, otherwise, you can certainly call the manufacturer and check (if you don't get an answer from someone else on the forum)?
