Good luck going forward!
Good choice with Meister Eiche Rustikal naturally oiled ;)
Exactly the "raised" edge areas of the screed and the transitions etc. were associated with bigger question marks for me..., additionally the temporal delay. Well, hopefully the professionals will do it properly.
What adhesive consumption have you had so far per sqm? I had originally calculated with 1-1.2 kg/sqm and then received the statement that in my case one would have to reckon with 1.5 kg. However, it could be due to the particularly long/wide planks (240x25cm).
What are the experiences regarding the baseboards?
I used to/so far always use the normal polished MDF ones, but the parquet layers advised to paint them wood-coloured if possible. In terms of price there is actually little to no difference.
Personally, I would have installed the baseboards on clips, so that later they can be repositioned easily if needed (e.g. if there is some settling and gaps form), but some wooden baseboards are only meant to be glued or screwed...
