Combining dry lining + wet plaster

[bmj1]

We will be dry lining our exterior walls with insulated plasterboard, to bring up u values.

 

Can we wet plaster the interior ones, or is that madness and we should use plasterboard throughout ?

[Big Jimbo]

I think wet plaster will cost you more, but may sound better when you give them a thump.

Nothing to stop you 

skim the ceilings and dry lined walls Then do the the wet plaster 

Use 100 mill fibre tape on board to solid wall

FWIW, I'd choose wet plaster too.

Cost wise 

there’s not a lot in it

I spent yesterday hacking off a thick layer of bonding plaster on a Victorian house.  It had really sucked up a load of moisture.  The previous owner had dabbed insulated P/B but one wall was part below ground, so that failed.  PITA.

Are you saying that as a good thing that it sucked up the moisture ?

No, a disaster.  Don't use bonding on any walls that are likely to be damp.  The moisture wicks though the bonding and spreads out.
