Emulsion paint drying time?

The emulsion has come off because the plaster has not been sealed. I always use Zinsser bulleye 123 to seal walls & never had a problem. I would sand down the walls to get all the loose paint then seal it then repaint.

The paint is not coming off the plaster. The top coat is coming away from the mist coat.

You could speak to the technical department at the paint manufacturer. They may be able to help you. There’s probably something gone wrong with the mist coat, even though it is adhering to the plaster. It might need more diluting than 15%? The usual recommendation is 25-30%, but maybe not for this particular paint?

However, whilst it would be good to know what went wrong, so you can avoid it in future, you currently have the issue of what to do about it. You have had several suggestions here, namely scrape off the loose paint, put lining paper over it, or simply accept it is loose and use a cutting in brush. 

It’s time now to make a choice. Cutting in brush is the least work.

The Leyland trade paint i used for the mist coat says on the back to mix with only 10% water. So I don't think adding even more water than I did would of helped.

That’s interesting. But, where do you go from here?

Good question. So I have sanded a small area of the mist coat.

I have then applied a coat of primer and will see tomorrow if it has adhered.

I have also applied a small amount of primer to the existing mist coat.

So tomorrow I will check if the primer has adhered to hopefully one of the test areas
