I've got a similar problem with our 1930s semi where a lot of plaster is blown with loose lime mortar underneath.

I'm going to soundproof the party wall which should mean they will end up with a decent smooth finish - regardless of the state of the wall/plaster underneath. I'm just not sure what to do about the other walls where large chunks of plaster are blown.

Should I take off what's there and have it re-plastered or is it more cost-effective to take it all off and go down the dot 'n' dab route?

The Wife seems to think we should get it all re-plastered from scratch but not sure it makes sense these days...

Any input from those with experience in this would be appreciated.

Thanks in advance!

Looks like it's me again, then, same answer as last time:

IMHO, for the purposes of insulation I'd suggest none of the above but plasterboard over studs, and preferably with the uprights wedged in floor to ceiling, not fixed to the wall. You don't have to listen to me though.

When I did this job, there was the advantage of putting in extra electrics using drywall back boxes (the existing galvanised boxes were rusted out) and all the cabling for a wall mounted TV - with extra studs to hang its bracket on.
