Hi,
So I have a landing wall that needs to be skimmed and a window reveal built up as an old wooden sash has been replaced by a upvc window and it's much smaller and thinner than the old window.
Now the situation is a bit complex as we have a solid, non cavity, wall where the window is, this runs into a timber internal stud wall part way along. And at the same point as the join there are 3 stairs. Obviously there are cracks all over the wall where the solid wall runs into the stud wall.
We can't afford to lose any space as this is a hallway/landing. This means any insulated plasterboard is out of the question (I assume) as we only have approx 25mm to play with once the existing render is hacked off the wall.
Someone has suggested using dot and dab with plasterboard on the brick wall and running this straight onto the stud wall and just ensuring that the board sits in the middle of the joint to reduce the risk of cracking.
I'm concerned that we might have issues with cold spots and damp if we dot and dab onto the external wall. There is currently no issues with damp on this wall currently and it's on the 1st floor so no problem with rising damp.
Is there a way to dot and dab and use some products that would avoid any cold spots/damp issues? Or would some other kind of solution be possible that could fit within the 25mm depth we have available?
I can provide a diagram if it's not clear what I'm working with from my description.
Thanks
