I've got a fairly small hallway where the old plaster was starting to come away from the bricks. I've stripped it back to the bricks and I want to drywall it with adhesive.
I checked the walls and they are not plumb, about 4-5 centimetres different between top and bottom of wall.
I've done it before in the bathroom and although I made the plasterboard straight when I put it on the wall, it seems the adhesive pulls the board in as it sets. I think because I had a large thickness at the top and a small thickness at the bottom the wall ended up wonky because the shrinkage depended on the thickness of the adhesive - I want to avoid the same mistake this time!
So, what's the best way to make sure when the plasterboard goes on the resulting wall is plumb?
Thanks for any suggestions,
