Question 5

How long does peel-and-stick wallpaper last and what are its downsides?

Accepted Answer

•

One of the biggest downsides to peel-and-stick wallpaper is that it doesn't last as long as traditional wallpaper. Its lifespan depends on several factors, including the quality of the paper, proper wall preparation and application, and the room's conditions. As a general rule, peel-and-stick wallpaper can last for at least five years, but this can vary significantly. Budget products may only last about 3 years, while higher-quality products can stay up for 7 years or more in ideal conditions. Factors that can shorten its lifespan include high humidity (such as in a bathroom), dirty walls, and low-quality paper. If used on flooring, expect it to last only 1 to 3 years unless sealed. However, the shorter lifespan can be seen as a positive, making it a great choice for people who enjoy switching up their interiors more frequently.
