Hi,I just bought a tarrace house and in living room I discovered that internal wall is overborded ,I'm planning renovation,and I don't know if I just need rip everything off and put new plaster on brickwork or just clean from wallpaper and painted.
It might well be simply dot n dab. Hard to tell from the pic. This is fairly normal as an easier way than full-on bonding coat and then skim.
Alternatively, it could be covering something more sinister such as damp. A lot of people do a lot of funny things, especially if trying to make it look nice before a sale.
What does the rest of the wall look like?
Is there any bad / damp smell about the place in this room? If all OK in general, I'd simply patch in any small dodgy areas and repaint. If it is just surface mould then scrape off paint back to plaster surface, treat, add a blocker as well if necessary and then repaint.
One thing I've learned in doing refurbs is to know when to stop. In every old property it'd be lovely to take everything back to brick but in reality it just isn't financially worth it.
Edit: just seen your second pic. Obvs battened and boarded.
I would scribe a horizontal line where you are, take the board off below in the damaged section, reboard with foil-backed board, skim and paint.
Thank you,it definitely was not done only for sale purposes,this house has got old wallpaper everywhere,gentlemen I bought house from lived here 50 years,there is no dump at all,this wall was wobbly a little and having plans for full house rewiring in January i was just wondering what was that wall about,I think I will remove everything from this wall and replaster if brickwork is ok.
The same has been done in next room but wall is painted(not wallpaper) so it there would be a problem with dump it will show, I will leave this one as you said...because it might ne never ending story...
