Hello!
I have a garage that stands on cinder blocks on a concrete slab.
On the inside, I have covered the walls with OSB and drywall.
It looks like this:
I would now like to plaster the cinder blocks with render.
But the question is, if I extend the render to come into contact with the drywall, will the drywall boards get damaged by the moisture in the render?
Do I need to keep a small gap between the render and the drywall?
Grateful for comments and experiences.
Best regards,
Fredrik

Yes, the plaster can handle the putty, as long as you don't wet the plaster too much. I don't know how you've done it; is the plaster on the Lecan or does it go outside? Either way, you will get a gap there if you're only going to putty. Why not putty the Lecan and fill the gap on the plaster? Then weave the walls = coarse weave.
this is how mine turned out

Hello!
Yes, the plaster is hanging a bit outside the leca.
But how do you mean that there will be a gap in any case?
My hope is to be able to pull plaster over the entire leca block so that it fits against the edge of the plasterboard.
But the damp plaster might loosen the plasterboard.
PS nice garage!!!

Thanks, yes, since they are different materials, gypsum and Lecan, they move differently with temperature changes. But if the gypsum now hangs down over the Lecan, the crack will be below the gypsum, which will not be visible. The crack will naturally be minimal, not big enough to throw a hat through. I would still use filler, for the last bit against the gypsum, since this side lacks cardboard. You can also place a thin strip against the edge of the gypsum, plaster up to the strip, and when the plaster has dried, remove the strip and apply a soft sealant there (synthetic sealant). As you can see, there are many possibilities, depending on how particular you are about it.
Trying to bring this thread back to life as I am in the same stage. I have osb and plaster 11+13mm which are both outside the leca. So it will be about 24mm to plaster up. How do I solve this in the best way without getting moisture in the plaster and the smallest possible gap?
The answers are actually already above, but I was wondering if someone has tried it and if the result was good?

Place masking tape around the edge and with some plastic about 0.5 m on the gypsum, then plaster the wall. You will need to place a trim over the joint, it will likely crack there, two different materials that move differently.
I continue with this question because I don't think it's completely clear.
If the conditions are like the above where the sill is flush with the Leca and the OSB+gypsum (24mm) "hangs" over the edge of the Leca and you want to plaster up so it aligns.
Do you need to somehow separate the underside of the boards from the plaster? If so, how?
One concern is the moisture in the plaster when applied. Another is the risk of water being absorbed into the plaster and up to the boards during, for example, snowmelt or washing of the floors, which you want to be able to do and is one of the reasons for choosing to build with a Leca base. A minor aesthetic crack between the materials doesn't bother me.
Can someone clarify this?

Don't know how big the risk is that the plaster will get wet from the render, but one idea would be to use those corner beads for plastered walls that you wet and glue on. If you cut away half of the side and then attach it at the bottom of the plaster, you get some protection for the plaster when you render, and then you can putty to get a nice seam. Just an idea.
