In the spring, I'll start re-paneling the house. As usual, there's a bit of a time crunch and also a lack of space, so I've started looking into pre-primed and intermediate-coated panels.
The question is, how good is the base protection and intermediate coating on factory-painted wood? Are there any tests on this? I don't doubt that it's good; I'm just curious.

It is panel from Moelven I have been looking at.

The information I received was that the boards are 'transport protected' and that you should oil the ends and prime them before applying the topcoat... The advantage is that you can put up the boards and wait until everything is ready before painting, even if it rains, etc., during the waiting period... Additionally, paint suppliers' warranties usually require that the same system is used all the way.
We bought pre-primed from moelven. And after we talked to colorama, they said it was only "transport primed," so we called and checked. It was primed with the same primer that colorama wanted to sell to us
So it was just time to start painting.
So it was just time to start painting.Guarantee, a bit too strong a word... Commitment is more correct:
From Alcro:
"BESTÅ PAINT SYSTEM
Alcro Bestå is a water-based facade system with primer oil, primer paint, and topcoat. Together, they provide your house with effective protection for up to 15 years."
When it comes to primed exterior panels, you might get different answers depending on whether you talk to a panel supplier or a paint supplier... What is stated about primed panels on Beijer's site and on Moelven's site sounds good...
The important thing is probably that the primed panel is overpainted within 6 months regardless of whether it is factory-finished or hand-painted:
"Moelven Bekväm is a primed quality panel ready for installation. 2 coats of topcoat are required on the installed panel. Topcoating should be done within 6 months."
Personally, I would not choose half-painted panels, as end grain oil on topcoat is not a good combo and I place all end grain in an oil can, so it is properly oiled, as end grain is the most sensitive. Furthermore, there are always gaps in installed panels, and they are well covered with 2 layers of topcoat...
But that's how I do it, others do it their way...

We used this one. Super nice to only have to paint once. Unfortunately, they have gone bankrupt due to the tough situation in the sawmill industry, but they will certainly be acquired soon.

Yes, I'm leaning towards buying primed and intermediate-coated. It feels like painting once will be enough, as it's not the most fun thing to do.
@jeppeknaster what kind of panel did you buy and how much did it cost?

Bought double tongue and groove 145mm half-phase. I have contacts there so I got a really great price. It probably costs around 25-30 SEK per meter normally.
In hindsight, I should have chosen the regular phase instead of the half-phase. I think it's easier to handle, especially if you're alone.

Bought grundad 22x100 at Hornbach for 11 kr per meter when I replaced the facade. Painted an extra layer on the ends. No proper longlife test yet - but two tough winters and rainy summers later, the house is still standing!
