Plastering using plaster boards to cover old plaster

[goteam]

We have had a quote for plastering. He seems very experienced and suggested rather than removing all the old blown plaster and stripping everything down which will be messy that he boards over it and then plasters on top of that. Does anyone have experience of this? It seems like cutting corners and I dont want it to create issues in the future if we ho with this method....

Errrrrr that doesn't sound right......if the old plaster is blown in places then you are going to fix boards through it which could then potentially really come away because the plaster behind it has failed

Also you are going to lose another 15mm of each wall so messes up where the walls meet the windows and any door architraves

Sounds like a bodge job to me

I'd hack off all the plaster yourselves - not an arduous job but it is dusty and messy if you are paying for new boards anyway

I'd also find another plasterer as he sounds rubbish

Thanks, sorry, he did say that would remove the blown plaster but as most of it isn't blown would board over that. It didnt feel right though

Honestly once he starts hacking off blown plaster then depending on how old it is most of the wall will probably come off anyway 🤣

Don't really understand his logic about only hacking off sections either - most older houses didn't plasterboard - they just had really thick plaster so if he hacks some off with the intention of boarding and replastering but he's going to board over the other sections then replaster then you will have a 15mm difference?

Thanks @ivfdreaming. It's a Victorian conversion flat so the plastering was done about 30 years ago. The problem wall with blown plaster divides what was once a bigger room. We want to sell in about a year so just want it to look nicer but dont want to put buyers off with a bodge job!

Its called dry lining... perfectly normal.
They just fill the joints between the boards rather than plaster the lot
Very common in new builds

Thanks @Alexalee that's reassuring. I'm pretty sure our bathroom fitters boarded over the existing walls actually but the difference was the plaster was fine. Am just worried about boarding over weak plaster.

Yes in new builds - they don't fix plasterboard to existing plaster - blown plaster at that.
