Hello!
We are in the process of renovating our kitchen and have a wall that is half plasterboard and the other half is a plastered chimney breast. The plastered part is about 140 cm, but only 60 cm at one end gets warm when we light a fire. What we intend to do is to apply plasterboard all the way up to where it gets warm.
The problem is that there is a level difference on the wall. The plasterboard on the plasterboard part of the wall was added later so that the level difference becomes the thickness of the plasterboard. We have understood that you can attach plasterboard to the plastered wall with gypsum mortar. But for reasons not relevant to this discussion, we need to apply yet another layer of plasterboard across the entire wall. How do you fasten plasterboard to plasterboard where you can't screw it in? Can you glue it? Or something else? It needs to hold for tiling.
Best,
