Please help!
I don't have a lot of info as I have just moved in... but this is the situation.
Bedroom with plaster and painted walls. Tried to paint white on the pink original paint using contractor paint as the first coat. Part of the original paint started to lift below and flake away whilst rolling. I scrapped that back and all the new and original paint came away in certain areas. Tried to paint over again and the same thing happened in different areas. Tried again with a white undercoat instead and the same thing has happened. Starting to wonder if the original pink paint is having a weird reaction to any new paint? It's a big room and I just don't know what to do!
Do I strip all the paint? If so how is the best way to go about this?
Please help!!
