About two years ago we decorated our bathroom. It had multiple layers of paint & wallpaper on the walls, so that all came off, leaving the bare grey plasterwork.
I used a vinyl silk emulsion to put on a couple of coats iirc. It went on but rather reluctantly, which should have been a warning sign.
A few weeks later & a few patches had popped up of tiny bubbles & small flaky areas, looking something like this:
However SWMBO is decorating the hall this weekend, so I figured I can't escape the bathroom anymore. I've just stripped the room & started to sugar soap the walls. I figured a bit of the paint would come off, I'd paint on a pva/water mix & then paint tomorrow...
Instead I've found the paint is coming off in huge areas:
It's almost like peeling wallpaper, though far more time consuming to get off:
Help!
What do I have to do to recover from this mess?
Am I going to have to pick all the paint off before I can cover it? I feel like packing a bag at the moment :/
How do I avoid repeating the problem when I eventually get as far as painting again?
Should I pva or just use watered down paint for the first one or two coats? Either way, what dilutions? We've bought a Dulux Bathroom soft sheen paint.
