What is an essential step after wallpapering to ensure longevity?

Smoothing out any air bubbles and trimming excess edges is essential after wallpapering because this step ensures a clean and professional finish. When wallpaper is applied to a surface, air bubbles can become trapped, which not only detracts from the appearance but can also lead to peeling or lifting over time. By smoothing out these bubbles, you create a firm bond between the wallpaper and the wall, enhancing its durability.

Additionally, trimming the excess edges prevents unsightly overlaps or uneven margins, which can attract dirt and wear down more quickly. This attention to detail contributes significantly to the overall longevity of the wallpaper installation, making it resistant to wear and maintaining its aesthetic appeal for a longer period. Proper finishing techniques play a crucial role in achieving a successful and enduring wallpaper application.
