![]() ![]() Lath and plaster have been mostly replaced with plasterboard (also a type of gypsum wallboard, although a bit thicker), since it is faster and less expensive to install. In the past, horsehair was used to help bind the plaster to the laths. Insufficient “keying” and the plaster will fall off the lath. After the plaster is completely dry, the walls are ready to be painted. A smooth, white finish coat goes on last. When the wall is fully covered, the vertical lath “guides” are removed, and their “slots” are filled in, leaving a fairly uniform undercoat. A helper feeds new plaster onto the board, as the plaster is applied in quantity. The applier drags the board upward over the wall, forcing the plaster into the gaps between the lath and leaving a layer on the front the depth of the temporary guides, typically about 1/4 inch. Plaster is then applied, typically using a wooden board as the application tool. Next, temporary lath guides are placed vertically to the wall, usually vertically at the studs. Each horizontal course of lath is spaced about 1/4 inch away from its neighbouring courses. The lath is typically about two inches wide by four feet long by 1/4 inch thick. Each wall frame is covered in lath, tacked at the studs. These are narrow strips of wood nailed horizontally across the wall studs. After the 1950s, plasterboard began to replace the lath and plaster process. ![]() Ceilings did have covings and ceiling roses.Lath and plaster was a building process used mainly for interior walls until the late 1950s. And the end result was great and there were no cracks in the 6 years we lived there however I am not sure if the ceilings were lath and plaster or had plasterboards already perhaps from the conversion. PS: We bought a period conversion flat (think it was also Edwardian) about 6 years ago and did a complete refurbishment including removing wallpaper and replastering. Perhaps no steamer and only use water spray? Are we likely to encounter problems after removing wallpaper? What are your suggestions/advice? Should we go ahead, get someone to remove wallpaper and re-plaster? I guess they'd need to be really careful when removing wallpaper from ceilings not to disrupt the lime plaster. We are concerned that removing wallpaper and replastering old lath and plaster ceiling might be opening a can of worms. We would like a good finish and something that would last a long time. We have allocated a budget for removing wallpaper, replastering and then decorating/painting. We are not looking to the do any of the work ourselves as it's too much work for us (both of us are very busy at the moment) though we are not afraid to get our hands dirty, we don't think we have the necessary skills. We could potentially do that in some of the rooms but it's not an option in the living room as we want to keep covings and ceiling roses. One guy said it's best to overboard (brining down the ceilings is out of the question) where possible. Couple of the plasters said it's fine and they can put fiberglass mesh if there are cracks. We've had quotes from a few plasterers and couple of them said it's risky removing wallpaper off old lath and plaster (especially the ceilings) and replastering as the old plaster under the paper could be already cracked, could get damaged, could crack in the future and will show through the new plaster, parts of the ceiling could collapse, etc. We want to retain period features like covings and ceiling roses. Both my partner and I have an eye for detail and we would like the walls and ceilings to be smooth before they are re-painted so we are thinking of removing lininng paper and re-plastering. ![]() On some of the walls and ceilings, lining paper has come off, can see the joints/lines, has bumps and has some halls (house used to be rented out to a family with kids). It's most likely lath and plaster underneath the lining paper. There's lining paper on all the walls and ceilings in 3/4 of the house (apart from the extension and loft conversion). ![]() We recently bought an Edwardian property (built around 1910). ![]()
