    In the photos it shows a ceiling which has been covered with artex paper.

    I have removed this today and underneath you can see a layer of chip paper i think.

    Everything is very loose and i will be removing all of this tomorrow with a steamer.

    Underneath the chip paper you can make out what the ceiling has been boarded with and it doesnt look like PB. I think it is ply board.

    So my question is, can i skim this ceiling ? If so would blue grit be best used over PVA.

    If i cant skim it, do i have to board it out.

    Ive also been watching some videos on doing a magic mix. Bonding plus multi. Could i use this mixture ?

    Just pick the surface of the board with something sharp to check because some older PB was very brown. I took some down here that the paper alone seemed stronger than the modern stuff, pb that is

    The ceiling is an older PB. I am just reboarding in 9.5mm tomorrow.

    Im not a plasterer so cant say if its necessary but when I overboard and where possible space the new boards so they overlap the old board joints.
