Good news... for the most part this worked. Was putting on my final coat and another bit bubbled. Luckily not a spot where I'd put filler. Otherwise you'd hear about a man on a rampage and the reason being painting plaster
So I've bought the zinsser, and applied it. I then put a skim of filler on it e.g polyfill? Once i sand that down I reapply the zinsser, do I then use a coat of emulsion on that then once dried use the final paint for the last coat i.e. vinyl?
Sorry if this is in the wrong thread. I'm new to the forum and don't usually use them. Paint is flaking of my plaster. Let the plaster dry for 8-9 months, done a mist coat and then painted. It's remained on the other 3 walls in the room and this is an outside wall where the bath used to be.
