Answer: This is an interesting question. The answer depends on the condition of the wall, and whether it has been plastered to a Level 4 or higher finish.
Throughout New Zealand, older houses are generally papered. This is because the joins in the wallboard or gib were plastered to a low level when the house was built.
Usually, if you have old wallpaper, the walls are not good enough to paint onto directly.
So, you must be extra careful when dealing with older homes. There is a high risk that the joins will crack with general house movement or earthquakes. Something we know all too well in Wellington!
When our team begins a job, we strip the wallpaper and reline the walls with a lining paper. Then paint the wall or, alternatively, hang new decorative wallpaper.
Bonus – If the paper is in good condition another option is to paint over the top of the existing paper.
