Can a layperson dare to handle the baseboards themselves?

It’s not about the cost of buying a miter saw either, you can already get one for around €100 that seems decent enough. I’m just afraid of the thing.

Then it’s a good decision not to use it. I think that’s totally fine and certainly better than some people overestimating themselves quickly. For example, I hardly ever, or never, touch the angle grinder.
Maybe one way is to buy moldings that are straight on the back; you can usually just place these against the guide and cut them at an angle. Or have you already bought all the moldings?

Hm....I feel it the other way around right now, for me the stuck part feels rather hard when walking. That's why I say you should definitely try it out for yourself.

Certainly a matter of taste as well. But when it's stuck, it’s harder, and the ground doesn’t give in. I’d say it’s like with cars: some like it to sit firmly on the road, others prefer the Daimler that rocks like a Hollywood swing over the asphalt and sings "Atemlos"...

My second outside corner already looks much better, I'm actually quite satisfied with it. There is no acrylic on it yet.

How would you do it with acrylic? Only run it along the top or also down to the floor? I thought if I don’t seal it down to the floor, water might get under the skirting board when mopping?

Great - I would do absolutely nothing more!

Definitely do not do anything at the top. Bottom left - yes, man, if it really bothers you... But I would also point out: in the first year the whole house settles again. So some recommend attaching the moldings only after a year because otherwise it will all crack anyway. So I wouldn’t smear any more acrylic on it either.

It continues little by little with the baseboards. The corners with the bay window were by far my hardest task so far. This side was okay, the other side of the veranda door was terrible, there I had the first wall in the house where the wall was really so uneven that the baseboard could not be applied straight. How annoying. I then did it so that the outside corner looked good, and at the inside corner the baseboard stood away from the wall, so I smeared in so much acrylic that I was amazed myself how much this method forgives. Now there is something in the corner, if you don’t know it, you don’t see it.

The corners here in the photo were then the second attempt, and with a straight wall, that went much better. Overall the task is doable, even for me with two left carpenter’s hands. So for people who ask themselves the same question: Go ahead. If you are not 100% perfectionists, then you can install baseboards. If I can get it done halfway properly, then you can do it much better.
