Hey Hoping you might be able to help - have had a few plasterers come around to quote me for works to my bedroom. All walls are lined with untold layers of paper and lining paper. The plaster certainly to the front wall (exterior wall) is blown. One plasterer has recommended, because the property is Victorian and may have lath plaster (?) that actually you could just plasterboard OVER the lined walls to avoid any uncovering of 'nasties'. Is this sensible advice / something that should be advised or something that should be avoided at all costs? We have chuff all cash so I think that was a reason for him making this suggestion. Your expertise would be HUGELY appreciated!
We had the ceiling in the basement lined with plasterboard (fire) in a Victorian property, The plaster just screw the sheets randomly. Did think he would try to find the joists, still up. The only thing is the screws are now rusting as it's damp in there. For solid external wall inside a Victorian property I would recommend using lime plaster (not cheap), there are lime insulating plaster available to reduce heat losses through wall. The only thing is most plasterer's have never heard of the stuff which i have found out. Walls need to breath. Another trick i did find out (cant remember from where? - maybe DIY manual ). If you have access to the inside to one side of a lath and plaster wall, the 'snots' - not sure correct term, can be binded using plaster.
Probably also suggested over boarding as saves having to remove all that wall paper first If lathe and plaster, and that old, could cause a hell of a mess stripping off paper. Plaster would more than likely come away, at least in some areas So PB over the lot. Has it been suggested to then skim over or to leave as bare PB (tapered edge) then tape and fill, then paint 2 nd option would save some money but paper surface of PB will get dents and knocks over time as much softer than a skimmed finish
Over board internal lath and plaster walls with 9mm. Quick and cheap and virtually no mess and agro of stripping walls. You may need to pack out door frames though, slam strip is good for this. If there are any sockets/ light switches, chop lath from around them and use fast fit boxes after overboarding.
Thanks everybody. So basically it's not a ludicrous suggestion that he's made? It is a feasible option. He's coming over again on Sunday morning to take a look but your thoughts have been greatly appreciated. But I'm guessing skimming after overboarding is sensible to strengthen the walls as per DIYDave comment?
Yes, you'll need to skim after over boarding. Not to strengthen, but just give a nice smooth surface ready for your decorating. If the guys who are doing the work are any good, you'll be surprised how quick the transformation can be. Make sure you quiz them about how they propose to sort out fitting electrical sockets, switches back etc. Good luck
Do not, under any circumstances, plaster over paper. You can. as has been suggested, 'board out' the room, but you will have to move skirting boards, picture rails, and electrical points and for the amount of work required, you might just as well do the job properly. Once the plaster is removed, the laths can be levelled with bonding coat before replastering. If you want to keep it authentic, find someone in your area who can replaster using lime.
