Fix nice drywall outer corners (a whole bunch)

[Karl_Pedal]

If you have properly spackled and taped, you don't need microlit.

Ok, then it will be microlit-free. I will spray paint the whole thing so there shouldn't be any noticeable differences caused by the filler absorbing more/less than the gypsum. But the question of the filler thickness remains. Is there any reason to use fine filler or is coarse filler sufficient?

Personally, I would have used fine filler, and if you've done well with the coarse filler, it's just an extremely thin layer of fine filler that hardly needs sanding, so it goes quickly.

coarseness? it should be smooth everywhere before you paint

After installing microlit on the ceiling for the first time yesterday, I have to say that it's not fun. Difficult to align the seams against each other (not overlapping). I managed okay, but not as well as I would have liked.

Hijacking the thread a little, but I think TS is also interested in answers to my question. If, like me, you have gaps of 2 mm at one end and overlapping at the other end of the microlit sheet. What do you think of my plan?
1 Prime
2 Fill the gap then sand
3 Plane the overlapping seam, then possibly fill if needed.

My thought is that after priming, it is easier to sand the filler and plane the seams when the microlit is harder from the paint. What do you think about that?

You can fill the gap directly, but planing the "overlap"....well, that's a good question. Microlit is quite difficult to handle, so maybe a coat of primer would help. But you could start by just applying paint over the seam and then try to plane off the "overlap". There's really no reason to prime the entire ceiling right away without fixing the seams first.

Yes, evenness is a parameter, but then there are different fine-grained fillers. I imagine that after two coats the difference in grain size is negligible, so I'm a bit unsure about the purpose of the fine-grained filler. It does shrink more when it dries, but what are its tangible advantages?

Well, the fine filler eliminates things you might see in angled light. You get an extra smooth surface. Most of the time, medium filler is enough.

I have now made some progress with this and have a question about raking light. I find it difficult to get good shadows when the spackle and plasterboard are gray and brown combined with the bright evenings of the summer half of the year. How do you best see where it is uneven? Should you apply a layer of white primer before illuminating?

You see significantly better after the first coat, yes. Try to light along the wall for the easiest control!

The easiest way is to apply a coat and then run a spotlight along the walls; this will reveal all defects.
