New paint cracking a week after painted on

Postby Notadiyexpert » Wed Sep 30, 2020 12:03 pm

Hi I had a decorator strip some wall paper and then paint the wall with dulux matt paint. Its been a week and I've noticed mosaic like cracks all over the newly painted wall. Any ideas on what has caused this and whether it was the decorator or the paint being faulty?

Hi notadiyexpert.
Most likely a reaction between the wallpaper paste residue and the paint - did the decorator wash down the walls before applying the paint?
Leave it for a few more weeks and see how bad it gets.
