Glue OSB to Leca

[pjop]

Hello,

I'm planning to glue OSB to an interior wall made of Leca. Is it possible, and would something like Ardex S48 or similar work?

As soon as I saw the thread I thought S48! Superior!!

Are there any particularly good reasons not to tighten some screws?

Time, the surface is not completely even. I thought it would be easier to pull a few strings and then attach the board compared to propping in between and then screwing.

You can do both to be on the safe side. Use 4-6 screws per sheet.

I don't know if I'm missing some detail, but you do need contact to be able to glue. Or are you going to glue over approximately the whole surface and then it "turns out" which points get contact?

I might not understand the situation, but I mean, like, if you know where to glue, you should be able to know where to screw too, right? But glue might work, I'm no expert. They usually hold for about 30kg per square centimeter or something like that, I recall, so let's hope you have some points with good contact and you're not planning to hang up really heavy things.
