Primer helps your wallpaper adhere firmly to the wall. It prevents the adhesive from being absorbed too quickly, which is especially useful in new homes where the walls tend to soak up a lot of moisture.

By applying primer first, you reduce the risk of your wallpaper coming loose. Simply coat the wall with primer and let it dry overnight. The next day, you can apply the wallpaper adhesive, knowing your wallpaper will stay perfectly in place.
