Hi,

I appreciate you can level individual batterns horizontally /
vertically using a spirit level or similar, but if the walls are bumpy
and irregular, how do you level the whole support across large spans
so that the plasterboard sits perfectly across the length and breadth
of the wall?

Do you fit spacers or something - I've been pondering the best method
but if there's a correct way to carry this out?

It's easier to level everything with a skim coat of plaster. You can
pack battens with bits of hardboard or whatever but it's a painstaking
job. Even more fiddly if you're fixing to the original joists

Most walls have painted paper and some (bathroom) has paint onto
ragged plaster / blocks. I have tried getting the paper off the
hallway, but it's a real pain. To do the hall / front room, bedrooms
(2 off), let alone anything else will take months at this rate to try
and get the paper off - that's before pva/plaster.

So, I thought I'd just plasterboard most walls as they are brick with
plaster on, but done to a wonky and horrible standard. It's an old
house. So I have to work taking into account all walls in the house
are painted paper over something, but no plasterboard in the house at
all at present.

btw - in the store the plasterboard itself seemed quite heavy - does
anyone know approximately how heavy general size plasterboard actually
is? I find it amazing that the dot and dab (?) fixing method works
with such heavy sheets of plasterboard.
