Please, please help me out with some hope/tips! We have just started renovating an old Victorian 6 bed house on a shoestring, only to discover that every wall was painted on top of UNsealed plaster, (various paints, mostly emulsion, some murals(!) in something satin-y)there is no way we can scrape it off the whole house (1 wall took us 10hrs) any tips for a method to speed things up? Steam? Heat? Sanding machine then seal what's left? PVA? We can't put up lining paper and we'll be painting the entire house white when we've solved this peeling problem. Thanks for reading. HELP!!!!!
