After properly preparing the wall, you can begin the installation process. Keep in mind that it's generally not advisable to apply peel and stick wallpaper when the temperature is below 50°F, as this can impact the adhesive's effectiveness.

Start by lining up the wallpaper according to the guideline. Peel about 12 inches of backing paper off the top of the peel and stick wallpaper, and apply it to the wall, starting from the ceiling. Ensure there is a slight overhang at the ceiling to avoid gaps due to an uneven ceiling. You will trim the extra wallpaper later.

For a more straightforward application process, peel only a tiny portion of the backing paper, maybe a foot, then line it straight. As you work your way down, gradually peel the rest of the backing off. To ensure proper adhesion, press the adhesive side onto the surface and smooth it out with a squeegee.

Continue placing the strips around the room, aligning the seams without overlapping. When encountering obstacles, make relief cuts to alleviate pressure and tension on the wallpaper, enabling you to attach the wallcovering without tearing it. After smoothing the strip around the obstacle using relief cuts, trim any excess wallpaper as you would at the ceiling and baseboards.

You'll need a putty knife or sharp edge to pry a single corner loose to remove peel and stick wallpaper. Then, pull the panel off the surface like a sticker.
