Common Installation Errors with Peel and Stick Wallpaper

We aim to empower homeowners and DIY enthusiasts to tackle their peel and stick wallpaper projects with ease and precision. So let's dive into the world of peel and stick wallpaper installation and discover the key techniques for achieving a flawless and visually stunning outcome.

Insufficient Wall Preparation

A key factor in ensuring a successful peel and stick wallpaper installation is proper wall preparation. Neglecting this crucial step can lead to a range of issues that compromise the adhesion and longevity of the wallpaper. 

Failure to clean the wall surface adequately: Before applying peel and stick wallpaper, it is essential to thoroughly clean the wall surface. Dust, dirt, grease, or residue from previous wallpaper or paint can hinder the adhesive's effectiveness. Use a mild detergent solution or wall cleaner to remove any contaminants and ensure a clean and smooth surface for optimal adhesion.

Not smoothing out existing imperfections or removing loose paint: Any bumps, cracks, or uneven textures on the wall can affect the wallpaper's ability to adhere properly. It is important to address these imperfections before installing the peel and stick wallpaper. Fill in cracks or holes with spackling compound, and use sandpaper to smooth out rough areas. Additionally, remove any loose or flaking paint to create a stable and even surface.

Improper Alignment and Pattern Matching

One of the common installation errors with peel and stick wallpaper is the lack of precision in aligning the wallpaper panels and properly matching patterns. This can result in a visually unappealing outcome and disrupt the overall aesthetic. 

Tips for achieving accurate alignment and pattern matching:

  • Begin by measuring and marking reference points on the wall, ensuring a straight starting line for the first panel.
  • Use a level or plumb line to ensure vertical alignment of each panel.
  • For patterned wallpaper, unroll and examine each panel before installation to understand the pattern repeat and how it aligns with adjacent panels.
  • When applying each panel, start from the top and work your way down, smoothing out any air bubbles or wrinkles as you go.
  • Use a wallpaper smoothing tool or squeegee to press the wallpaper firmly onto the wall and ensure proper adhesion.

Air Bubbles and Wrinkles

Air bubbles and wrinkles can compromise the smooth and flawless appearance of the wallpaper. Air bubbles can form when the wallpaper is not properly smoothed onto the wall, resulting in trapped air pockets. Common causes include inadequate pressure applied during installation, improper removal of backing paper, or uneven wall surfaces. It's important to address these factors to minimize the occurrence of air bubbles.

Effective techniques for removing air bubbles and wrinkles from peel and stick wallpaper:

  1. Begin by applying the wallpaper in the center of the panel and gradually work your way towards the edges. This helps to evenly distribute the wallpaper and minimize the chances of trapping air bubbles.
  1. A wallpaper smoothing tool or squeegee is a valuable tool for eliminating air bubbles and wrinkles. After applying the wallpaper, use the tool to firmly press the wallpaper onto the wall, working from the center outwards. Apply even pressure and move the tool in smooth, sweeping motions to ensure proper adhesion and eliminate any air pockets.
  1. If you notice the presence of air bubbles, gently lift the affected area of the wallpaper and use the smoothing tool to press out the trapped air. Start from the center of the bubble and push towards the edges, smoothing the wallpaper as you go.

Insufficient Adhesion and Peeling

Insufficient adhesion and peeling are common problems that can arise when installing peel and stick wallpaper. Tips for ensuring proper adhesion to prevent peeling:

  • Thoroughly clean the wall surface
  • Apply sufficient pressure
  • Use a primer if necessary
  • Avoid excessive moisture exposure

If you notice any sections of the wallpaper that have started to peel, it's important to address them promptly to prevent further damage. Here are the method for re-adhering peeled wallpaper sections:

Apply a small amount of adhesive to the back of the peeled section and press it firmly onto the wall. Follow the manufacturer's instructions for the adhesive and ensure that it is compatible with the peel and stick wallpaper.

Overlapping and Gapping

When installing peel and stick wallpaper, one of the common errors is improper handling of overlapping or leaving gaps between wallpaper panels. Overlapping occurs when the edges of two adjacent panels are not aligned correctly, resulting in an uneven and unprofessional appearance. On the other hand, gaps are spaces left between panels, leaving visible seams that disrupt the overall look of the wallpaper. These mistakes can detract from the intended aesthetic and compromise the seamless finish of the wallpaper installation.

Remember to always follow the manufacturer's instructions and guidelines when making adjustments to your peel and stick wallpaper. By taking the necessary steps to address overlaps and gaps, you can achieve a flawless and visually appealing result in your wallpaper installation.


In conclusion, the installation of self-adhesive wallpaper can be a straightforward and enjoyable process if you follow the instructions provided by the manufacturer. By avoiding common mistakes you can ensure a seamless and visually pleasing result.
