Hi Matthew, The type of wallboard on the ceiling is generally 13mm ultraline. This gives a superior finish however you could use standard 13mm wallboard. Generally in older homes, ceilings can sag over time so it's worth checking to see if this is the case. It could be worth while adding a strong back (2 x 150x50 nailed together spanning from wall to wall) across the top of the rafters and using z nails to pin the rafters to the strong back to straighten the ceiling. For kitchens and bathrooms it's best if you use a wet area wallboard such as GIB aqualine. SR
You can do restricted building work yourself on your own home if you use the Owner Builder exemption provision in the Building Act. You do not have to employ a Licensed Building Practitioner or have one sign off the work for you.
You would be better off following the plastering guidelines layed out in the Gib book. Air drying compound is not recommended for first coat and you'll need 3 coats total for a level 4 finish.
Because, as you can tell from the accent, he's not in the UK. We're in New Zealand where we don't skim the whole plaster board. It's ready to paint when he said it was ready to paint.
