We have recently had a decorator in to paper over a 12month wall. The house was a new build 12 months ago and the wall was painted with white emulsion. The decorator has primed the walls in prep for the wallpaper, left it to dry for 24hours and following the application of the paper it has fell off the wall and completely removed the paint leaving the bare plaster on show. Could this be an issue with the adhesive or would it be a case that the paint was not correctly applied in the first place ie Mist coat, dry time and emulsion over it?
The walls were probably not primed before painting. Builders often do not flood the walls, as well as do not dilute the paint with water for the first painting. This resulted in poor adhesion of the paint, necessity of priming 2 or 3 times before putting the wallpaper.
Paint not applied correctly in first place. To cut cost or short cut!
It sounds to me that a mist coat wasn't put on properly when the building was first painted, Unfortunatly you will have to seal the plaster before putting new wall paper up what can easily done.
Hope that helps
New buildings it always happen
Because the house never been use so its first 12 months the staff is getting use to hot cold and people use it if you know what I mean
Wallpaper is never a good choise but if was painted you will see cracks on the wall unless is A1 painting
My theory is that there's a possibility the walls hadn't been mist coated/white washed. So if that is the case, then paint will not adhere hence the wallpaper paste not adhering fully.
The basic question that comes to my mind with this issue is did the decorator sand down the plaster before applying the paint, with the house only being 12 months I can imagine the plaster to of been left with a polished marble like finish which paint will not stick to.
