Hello,
I'm in the process of renovating our upper floor and am about to fix the blemishes that have appeared on the plastered brick walls after tearing down a wall. I have experience with plastering from before and know that it is tedious and boring, and have considered gluing renovation plasterboard on the walls instead. Since some of the walls are exterior walls and everything is made of brick, is it appropriate to glue renovation plasterboard on these, or is there a risk of moisture and mold between the board and the wall?
I've searched around a bit on this but haven't found anything that directly says it's okay, so I appreciate all responses

Renovation plasterboard doesn't insulate anything. If you don't add any insulation, the wall surface will be approximately as warm/cold as it is today. This means that there probably won't be more condensation on the walls than you have today.
In other words: if the space is heated today and you don't experience condensation on the walls, the risk of problems should be minimal.
One could argue that if you glue the boards, you won't have an air gap that can dry any potential condensation that occurs. On the other hand, I learned in physics in middle school that moisture dries outwards if it's warmer on the inside (I think it was the second law of thermodynamics?). Since you don't have a moisture barrier on the wall, any moisture should have the opportunity to dry out anyway.
Personally, I would probably prefer plastering, but that's because I think plastering is more fun than installing plasterboard.
