    What is the best option for making good thus cieling?

    We're eight months in to owning a 1905 Edwardian house and trying to get one of the two main rooms redecorated.
    Having removed the lining and textured paper, the decorator says it needs repair rather than repapering and the plasterer who was filling electricans chases at the time suggests some small sections are coming away and need removing, which he proposes to fill with bonding before taping the cracks and skimming the lot.
    Three men, one day, £700 or £600 cash.

    For the brick walls he used Limelite lime and cement Renovating Plaster for filling in the chases, for the lath and plaster stud walls just normal Thistle MultiFinish.

    Due to the age of the building and cornice work I would like to be as sympathetic as practical.
    However we are also living in the house, so there is obviously a time limit to getting it less like a building site!

    Photos of the room attached.

    The plasterer is due tomorrow, so this is all very late in the game. I just don't want to do the wrong thing and loose the original look and ook , the ceiling and wall moulding etc.

    It's hard for me to tell if the cracks are the plaster coming loose from the laths or just from movement of the laths, or to know if 100mm scrimtape and 3-7mm of gypsum as per plasterer, will do the job long term. We're quite happy with the linning paper look, as would rather it look in keeping than ice white perfect modern crisp look. But would obviously like it to last and look smart.

    At the short edge where meets the wall (beyond the ceiling moulding) it clearly dropped a bit relative to the wall, maybe half an inch in the middle, but it looks to me like it's the whole ceiling/joists that have come down in an arch that the plaster coming loose, it all appears quite solid. I've poked a whole in it and what I find fits with that.

    More photos.


    Thanks

    Did the bonding go straight onto the laths? Looks good to me

    Looks nice but I'm afraid that is a short term fix the scrim won't hold that back for long

    Hell of a room if truth be told, we love it. The property is half a larger house, circa 1902, so the room sizes reflect that.

    Sealed with a PVA & SBR wash and then pushed up into the lathes.

    They have certainly done a high quality job of the job in hand.

    We shall see. Each crack was inspected and any that moved, which was not many, where racked out and bonded. Obviously at this point I hope it lasts us decades, else it may get re-papered.

    Out of interest, if you where to have the time again, what alternative work would you have done?

    Thanks

    I hope I'm wrong but there was too many cracks for my liking but saying that I would have done the same if it was my ceiling because it wouldn't have cost me 700 and if the cracks came back I could still sort it but if I wanted to make sure 100% I may have done this https://www.diynot.com/diy/threads/overboarding-a-coved-ceiling.401064/

    Ok, thanks .It's unclear from the link what the actual suggestion is, however the nature of the coaving in my mind recludes simple overboarding. Lime skims appear uncommon. Hence any other option would be much more drastic, removing the majority of the old like plaster and either replacing like for like or overboarding upto the coving, or even remvirem the coving and re-running it in wet plaster.
    I'm summary, while I had some cold feet going in, it feels like what we have done is ok. Hopefully we now have a solid enough platform for decdade to come. Else is some small cracks come back lining paper may be an option .

    I will report back in a few years if I remember!

    The link information is as clear as day even providing a link to another forum where it is explained in detail but I will explain in layman's you overboard ceiling then you stop short at the coving by a couple of cms you then use a plasterboard bead to create a shadow bead this bead gives the illusion of being part of the cornice in other words you are adding a step to the cornice when done properly it looks nice and you get a nice fresh ceiling to skim this should in my books have been offered as an option now as for reporting back in a few years if the cracks do come back it will be a lot sooner than that

    For the money I think you have a good job, and you seem pleased.

    Overboarding has many advantages, but somehow takes the history and originality out of a building, not that most would care nor notice.
