Help!! After stripping off the wall paper I discovered the walls were covered in a pink shiny paint. I sanded this down and gave the walls a quick wash will watered down emulsion to cover some patches which were just plaster. I then used Polycell basecoat with a matt emulsion on top. The paint has bubbled all over. I tried sanding down the bubbled areas and reapplying base coat but more bubbles appeared in other areas when I put another coat of emulsion on top. I have now stripped the paint off back down to the pink base coat but I'm not sure how to proceed to prevent the bubbling happenning again.
Please advise??
