Against my better judgement I decided to remove the lining paper on my bedroom walls and paint directly on to the plaster beneath. I suspected I would need to do some patching and sanding, but it turns out the paper was the only thing holding the walls together. In some places, several layers of plaster have come away, revealing some kind of rough, crumbly base layer (see images) [Edit - further research makes me think this may be sand and lime render?]. This is a c1900 terrace house and this is a load-bearing internal wall. I suspect this is beyond simple repair and it will either be a case of scraping off all the plaster and starting again, or possibly overboarding and skimming. Any suggestions/advice would be gratefully received.
Thanks,
Phil
