My first post, I am not a plasterer but need advice, and will probably be coming back for more advice in the coming years! The house we have just bought is a doer upper, its a Victorian terrace that has all woodchip wallpaper on every single wall and ceiling in the house. Under this is a couple layers of paint, and under this seems to be a washable green or reddish pigment (limewash, distemper?). All the walls are plastered in lime plaster. I have just started stripping the kitchen, which is proving painful. The woodchip paper is very stubborn, sometimes i can scrape the paint off underneath, sometimes seems impossible. Sometimes the paint comes off with the top thin layer of plaster, in that almost resembles sandpaper. On one wall I have found that the bottom metre or so has a gypsum plaster finish, and then rest of wall is lime plaster. It is odd that the area where they have used gypsum was damp and patchy from condensation. This tells me it is not a good idea to skim the lime plaster with gypsum. In areas where I have got down to the lime plaster, it seems in decent nick, but unfit to paint over, it will crumble if rubbed hard enough, but feels structurally sound. What would my options be to finish the wall? I am tempted to knock the gypsum plaster off and replaster that area with limeplaster. However, i then want to skim the whole wall to get an even finish. Is there a lime skim that can be used? As I say, I'm not a plasterer, but done a bit of googling, still left with questions!
