We moved into a property just under a year ago. The previous owners were HEAVY smokers so we scrubbed the whole property down. Walls were washed with sugar soap, cleaned with water, dried off and sealed with Zinsser Bin before applying 2 coats of emulsion.
Over the course of the year this one section of paint has began to flake away quite drastically, see pics.
Unsure what's causing it. This wall is a shared wall with our neighbor so could be some damp ingress from their side, or it could be condensation build up but it does seem like a strange place for it, and we've tried using a dehumidifier right by it to no avail.
Anyway I digress - What's the best approach to redecorating this to make sure we don't have the same issue another year down the line?
Thanks in advance!
