Is it any more expensive/time consuming/difficult for a professional plasterer to plaster over timber laths which are already in-situ compared to plastering over pre-installed plasterboard of the same square area?

Thanks.

Thanks - it would just be standard builders-merchant's plaster in either scenario.

I am not a plasterer but I believe that horse hair lime type plasters were originally used to deal with both the gaps and suction.

I would expect that you need a specialist plasterer (and pay a premium accordingly).

Okay - so regular plaster may not be suitable to plaster over laths; I hadn't thought of that possibility.

If any plasterers can confirm? Thanks.

confirmed.
So if regular plaster cannot go directly onto laths, and needs to be a lime plaster - so this needs to be a specialist plasterer only? Regular plasterers can't use lime plaster directly onto laths?

(In case relevant, the house is not listed).

If you can find one who will want to do it.
There are bagged renovation lime plasters available , but are hugely expensive in comparison and inreasing constantly .

Is there a reason why you don't want to remove the laths and use plasterboard?

Originally I had assumed regular plaster could be placed onto laths by a regular plasterer, and if this was the case, it would mean there wouldn't be the extra time/expense of removing laths and placing new plasterboard in place.

I now realise this wouldn't be the case.

possom i see you have been asking this question since 2018? If the laths are bare there is nothing to stop a backing coat of bonding being floated on you will have to treat the laths then apply whats called a pricking up coat followed by a scratch coat then top coat the exact same procedure as if you use lime "ive done both" if you go the board option there will be a lip around the wall where the old plaster on the ceiling would have been and it will need to be chopped out and filled as the board will not quite reach it , the choice is yours wich way you want to go btw there has is lots of posts on this subject over thet years that you can read

Many years ago I had my laths plastered over using ordinary plaster, seemed to work well.

But a tradesman coming in now will want to do whichever is quickest and easiest for them, this wold be board and skim it.
You want more then you will pay for it.
If your not bothered about the originality of laths then remove them all ready for boarding.
