It doesn't really matter if TS uses craftsmen or not.Bernieberg said:
For some reason, TS wants to use protective covering, so there is obviously a need.
My opinion is then not to be stingy with a few kronor and use something as poor and unwieldy as mjölkpapp when there are much better materials available.
Additionally, the costs can be quite extensive if the protective covering were to fail.
As mentioned, it completely depends on what's being done and what's being covered. At home, I mostly use regular brown paper, and it's worked well for me. Besides, I've never seen the alternative you're talking about; around here, builders use milk paper, and, for example, Myresjöhus sends that with their builds for floor covering, so it can't be completely useless.T totalpeter said:
Offtopic: I think both forms of building have their challenges, and there's a learning curve to transition. Personally, I enjoy the flexibility of being a "trailer carpenter" and will continue as such until I find my dream job as a janitor.
Oh, what a discussion it became over a little paper 
I need milk paper to avoid messing up the tiled floor when plastering and painting walls and ceilings. I think paper works well. But I see there's a painting mat at Jula for 99:- for 10m2, while Byggmax charges 169:- for 25m2. That gives a difference of about 3:- per m2, which isn't much. But as I said, I'll go with paper. I'll try Byggmax's variant tomorrow.

Go with mjölkpapp. I do too, and the durability exceeds the needs for that type of home renovation.
