Peeling paint

Hi,


I have a little room attached to my kitchen which serves as a pantry. It has three external walls (the fourth is joined to the kitchen) and is quite cold (no radiator or anything).



Anyway, last year, we redecorated the room. In areas where there had been some historic damp (ie no damp there now), we sprayed the relevant parts of the wall with that stuff that stops damp marks showing through the new paint. Then we painted the walls with normal emulsion for walls.



Now the paint is peeling in large random patches (not confined to the sprayed areas) and looks unsightly. Any ideas what is causing it and also what we can do to prevent it happening again when we get round to repainting?


Thanks















I didn't find the right solution from the internet.
