Hello,
I have a doorway/passage in a lecawall in the basement that I need to clad with something. I've glued drywall on the actual walls in the rooms connecting to the wall, but I'm considering attaching MDF inside the opening itself. However, I haven't managed to find anything on whether MDF is suitable for this purpose (installation against Leca in a dry basement) and, if so, how to properly fasten it. There are plenty of MDF screws, but I haven't found anything that seems recommended for the MDF+Leca combination.
Anyone have a good tip?

MDF is very moisture-sensitive, but if you're confident that the basement is dry, then just go for it. It will be much better if you paint the MDF even on the side against the wall. Wooden molding is less moisture-sensitive, but I guess it's quite a broad area since you write passage, so it probably won't work. Otherwise, you might consider plaster or stucco, perhaps?
Fastening for something like this (which I assume is mainly for aesthetics) doesn't matter too much. Just choose a reasonably long screw that can be countersunk into the MDF and anchor in the leca, or if you want to make it even easier, you can use nail plugs.

If you are going to glue, then contact adhesive or MS polymer adhesive are what I find recommended as alternatives for MDF panels.
Moisten the wall with a spray bottle, apply plaster with a 10mm comb, and press firmly. It sticks like a rock!
If you mean there is still a doorway, build a framework in the doorway that you attach to the lightweight concrete, and then screw the board into the studs. You might as well use OSB and plasterboard. The MDF board will give a different painted surface and also moves more than plasterboard, making it more prone to cracks in the filler/joint later.
