five to seven years
When correctly applied, quality peel-and-stick wallpaper can last five to seven years or more. Peel-and-stick wallpaper will last longest on smooth-textured, properly prepared walls and in areas without high humidity or temperature fluctuations.
Peel-and-stick wallpaper is best in rooms with low humidity and low traffic, as they tend to be less durable than permanent wallpaper, and high levels of moisture will cause the paper to peel away from your walls. For this reason, we don't recommend applying peel-and-stick wallpaper in bathrooms or kitchens.
