Peel and stick wallpaper is a fantastic, budget-friendly option to update your home decor without the mess, hassle, and cost associated with traditional wallpapering. It's a simple, effective way to refresh any room in your house with minimal effort. However, as with any DIY project, there are common pitfalls that can turn a smooth installation into a frustrating experience.

If you're planning to install peel and stick wallpaper in your home, it's important to avoid these common mistakes to ensure a professional-looking finish. In this article, we'll walk you through the most frequent errors people make during installation and how you can sidestep them.

  1. Skipping Wall Preparation

One of the most common mistakes people make when installing peel and stick wallpaper is neglecting to properly prepare the wall. While peel and stick wallpaper is designed to be easy to install, the success of your project heavily depends on the condition of the surface you're applying it to.

Why It's a Problem:

If the wall is dirty, textured, or uneven, the wallpaper will not adhere properly. Dust, dirt, and grease can prevent the adhesive from sticking, leading to peeling corners, bubbling, or peeling edges. Uneven walls can also cause the wallpaper to wrinkle or not line up correctly.

Solution:

Before applying peel and stick wallpaper, thoroughly clean the wall. Use a mild detergent solution to wipe down the surface, then rinse and dry it completely. For best results, ensure the wall is smooth and free from imperfections. If you're applying wallpaper to a painted wall, consider lightly sanding any rough areas to achieve a smoother surface.

  1. Failing to Measure Properly

Accurate measurement is crucial for a successful peel and stick wallpaper installation. A lot of people rush through this step, thinking that they can simply eyeball it, which often leads to wasted wallpaper and uneven cuts.

Why It's a Problem:

Incorrect measurements can result in gaps, crooked lines, or misalignment when applying the wallpaper. If the wallpaper doesn't cover the entire surface or is uneven, it can look unprofessional and disjointed.

Solution:

Take the time to measure the wall carefully before you start. Use a level to mark a straight vertical line where the first strip of wallpaper will begin. This ensures that the wallpaper is aligned properly and prevents it from becoming crooked as you go along. Also, measure the length of the wall and cut your wallpaper accordingly, leaving a small amount of extra material to trim at the top and bottom.

  1. Not Using a Level

Many DIYers neglect to use a level when installing peel and stick wallpaper, thinking that the pattern will mask any minor misalignments. However, even slight angles can become more obvious as you add more wallpaper, leading to a crooked or uneven look.

Why It's a Problem:

Without a level, the wallpaper can start to look skewed or tilted, especially if you're working with a large surface area. Once a strip is crooked, it can be challenging to adjust without removing it, which risks damaging the wallpaper or the wall.

Solution:

Invest in a good quality level and use it to mark your starting point and ensure each new strip is installed straight. This will give your wallpaper a clean, professional finish and help maintain consistency throughout the room.

  1. Applying Wallpaper Too Quickly

While peel and stick wallpaper is easy to install, it's important to take your time during the process. Rushing through the installation can lead to mistakes like misaligned wallpaper, air bubbles, and tears in the material.

Why It's a Problem:

If you're too fast when applying the wallpaper, you might not have the chance to smooth out wrinkles or bubbles. Once the adhesive sticks, it's hard to reposition the wallpaper, and any mistakes made early on can be difficult or impossible to fix later.

Solution:

Apply the wallpaper slowly, making sure to smooth out the material as you go. Start from the top or bottom and peel the backing off incrementally, smoothing the wallpaper against the wall in sections. Take breaks if necessary to ensure everything is lined up and aligned properly.

  1. Ignoring Pattern Match

Peel and stick wallpaper comes in a variety of designs, many of which are patterned. If you're working with a wallpaper that features a repeating pattern, it's essential to align the design correctly as you install each strip.

Why It's a Problem:

If you don't pay attention to the pattern match, the wallpaper can look mismatched or jarring when the design doesn't line up. This issue can be especially noticeable in rooms with large walls or prominent patterns like florals, stripes, or geometric shapes.

Solution:

When cutting the wallpaper strips, carefully check the pattern alignment. It's usually best to start at the top of the wall and ensure that each subsequent strip matches the previous one. If necessary, trim the wallpaper slightly to ensure that the pattern aligns correctly across seams.

  1. Not Applying Enough Pressure to Seal the Edges

Once the wallpaper is applied, many people forget to apply enough pressure to the edges, leaving them prone to lifting and peeling over time. This is especially problematic in areas like corners, windows, and door frames.

Why It's a Problem:

Peel and stick wallpaper relies on pressure to bond effectively with the wall. If the edges aren't properly sealed, the adhesive may loosen, causing the wallpaper to peel back and look unsightly.

Solution:

Once your wallpaper is in place, go over the edges with a smooth, firm object like a wallpaper smoothing tool or a credit card. This ensures that the edges are properly adhered to the wall and prevents peeling later on.

  1. Using the Wrong Tools

Using the wrong tools for installation can lead to uneven cuts, wrinkles, or even tears in your peel and stick wallpaper. Some people use sharp objects or heavy-duty tools that can damage the wallpaper, while others neglect to use smoothing tools to ensure a seamless finish.

Why It's a Problem:

Incorrect tools can cause damage to your wallpaper, making it harder to apply and causing imperfections in the final look. A poorly applied wallpaper will not only look bad but may also start to peel or bubble over time.

Solution:

Use the right tools for the job. A utility knife with a sharp blade is perfect for trimming the wallpaper, and a wallpaper smoothing tool or a plastic squeegee is ideal for removing air bubbles. Avoid using anything too sharp or heavy, as this could puncture or tear the wallpaper.

  1. Forgetting to Leave Extra Material for Trimming

It's easy to get excited about installing peel and stick wallpaper and forget to leave a little extra around the edges for trimming. While it may seem like an unnecessary step, leaving excess wallpaper ensures that the edges are neat and that you can trim precisely.

Why It's a Problem:

If you don't leave extra material, your wallpaper may not cover the entire wall or could be misaligned along the edges. This can lead to uneven finishes and gaps that detract from the overall look of the room.

Solution:

Always cut your wallpaper with a little extra material around the edges. Once you've applied the wallpaper, you can trim the excess with a utility knife to create a clean, finished look.

  1. Not Taking Temperature and Humidity Into Account

Peel and stick wallpaper relies on adhesive to stay in place, and temperature and humidity can significantly affect how well it sticks. Applying wallpaper in a room that is too hot, humid, or cold can cause the adhesive to weaken, leading to bubbling, peeling, or difficulty with installation.

Why It's a Problem:

Extreme temperature or humidity levels can affect how well the wallpaper adheres to the wall, causing it to lift or wrinkle over time. If the room is too humid or too dry, the adhesive may fail to bond properly.

Solution:

Before starting your installation, ensure that the room is at a comfortable temperature and humidity level. Ideal conditions are around 65-75°F (18-24°C) with moderate humidity. Avoid applying wallpaper in rooms that are excessively humid, like bathrooms or kitchens, unless you're using wallpaper specifically designed for these areas.

  1. Not Taking the Time to Smooth Out Air Bubbles

Air bubbles are one of the most frustrating issues when it comes to peel and stick wallpaper. While it might seem like a small issue, leaving bubbles behind can create noticeable imperfections and make the wallpaper look unprofessional.

Why It's a Problem:

Air bubbles not only affect the appearance of your wallpaper, but they can also weaken the bond between the adhesive and the wall. If not addressed, the bubbles can cause the wallpaper to peel off prematurely.

Solution:

As you apply each strip of wallpaper, use a smoothing tool or your hands to gently push out any air bubbles. Start from the center and work your way outwards to ensure that all bubbles are removed. If a bubble remains, carefully peel back the wallpaper, smooth it out, and reapply it.

Conclusion

Installing peel and stick wallpaper can be a rewarding DIY project, but it requires careful attention to detail and patience. By avoiding these common mistakes, you can ensure that your wallpaper looks flawless and lasts for years to come. Remember to take your time, measure accurately, and prep your walls properly for the best possible results. With these tips, you can enjoy a beautiful, professional-looking home without the hefty price tag.
