Wallpapering a room or installing a wall mural is a fairly easy, do-it-yourself project. However, some challenges can pop up, like wallpapering corners.
Many beginners are tempted to run a wall mural panel to the end of the wall, crease it, and continue onto the adjoining wall. This method doesn’t allow for the wallpaper panel to adhere properly, so the paper often pulls away from the wall not long after it’s hung. Although it requires a specific technique, you can get fantastic results wallpapering inside and outside corners by following these simple steps.
Wallpapering Inside Corners
Use this easy wrap-and-overlap seam method to wallpaper interior corners.

- Hang the wallpaper panel and smooth it into the corner.
- Allow the additional ½ inch to overlap onto the adjoining wall and smooth it out. Trim off any excess at the ceiling and baseboard.
- Align the next panel and allow it to overlap the ½ inch extension. Make sure the pattern or design matches with the previous panel.
Wallpapering Outside Corners
Outer corners pose two challenges when wallpapering. Since they physically stand out, they often face a lot of wear-and-tear as people brush against or knock into them. Outer corners, too, are more noticeable and can draw attention to any flaws. For these reasons, it is best to avoid placing a wallpaper or wall mural seam directly on the corner. The following steps will give you great results and ensure your wall mural’s longevity.
