I have a piece of wall where I need to fix plasterboard to some blockwork to align with adjacent stud and plasterboard. This is because I have been advised that it would be a bad idea and highly likely to crack if a wall is part wet plaster and part board and skim on studwork - best to board the whole thing and skim.

I need to fit the plasterboard closely against the blockwork (it is an internal wall, so no damp/thermal issues), so within 3.5mm of the blockwork.

I am thinking I could achieve this using (a) foam plasterboard adhesive and (b) adding a few screws into the blockwork.

 

What is the best screws/fixings into the blockwork and do I need to prime them before skim coat ? Do I need to pre-drill the wall and any tricks for aligning boards with holes ?

How can I make sure the adhesive isn't too thick ? Just apply in small beads through a thin tube and nozzle ? Or press to the wall before the foam gets tacky to squash it thin ?

Not directly relevant to your needs, but might give some general context to various options. Very thorough video.
