Avoid Wallpaper Mishaps: 5 Common Mistakes to Watch For



Wallpaper Installation Hacks You Need Now

Wallpapering can be a fantastic way to transform your living space, adding style and personality to your home. However, it’s not without its challenges, and making mistakes during the wallpapering process can lead to less-than-desirable results. To help you achieve a flawless wallpaper installation, here are five common mistakes to watch for and how to avoid them:

Insufficient Wall Preparation

Mistake: Neglecting proper wall preparation is one of the most common mistakes in wallpaper installation. Failing to address imperfections, dirt, or old adhesive residue on the walls can lead to an uneven surface and poor adhesion.

Solution: Before applying wallpaper, ensure your walls are clean, smooth, and dry. Fill any holes or cracks with spackle and sand them down. Remove old wallpaper and adhesive residue. Use a primer to create a smooth and uniform surface for better wallpaper adhesion.

Incorrect Measurement and Cutting

Mistake: Cutting wallpaper strips too short or too long can result in mismatched patterns or uneven edges. Inaccurate measurements can lead to frustrating adjustments during installation.

Solution: Measure your walls carefully, accounting for any pattern repeats. Add a few extra inches to the length to allow for adjustments and trimming. Use a straightedge and a sharp utility knife to cut your wallpaper precisely along the measured lines.

Not Allowing Proper Paste Activation Time

Mistake: Rushing through the wallpaper paste activation step can cause problems with adhesion and pattern matching. Some wallpapers require specific soaking times for optimal results.

Solution: Follow the manufacturer’s instructions for wallpaper paste activation. Typically, you’ll need to let the pasted wallpaper “book” or rest for a specified amount of time before hanging it. This allows the paper to expand and ensures even adhesion.

Overlapping Seams Incorrectly

Mistake: Overlapping wallpaper seams too much or too little can lead to visible lines or gaps between strips. Achieving a seamless look is essential for a professional finish.

Solution: Properly align the edges of adjacent wallpaper strips without overlapping them. Use a wallpaper seam roller to gently press down and blend the seams. Be precise and patient to create a seamless appearance.

Ignoring Air Bubbles and Wrinkles

Mistake: Failing to address air bubbles, wrinkles, or creases during installation can result in an uneven and unattractive wallpaper surface.

Solution: As you apply each strip of wallpaper, use a wallpaper smoother or a soft, flat tool to press out any air bubbles or wrinkles. Start from the center and work your way toward the edges to ensure a smooth finish.


  1. Can I wallpaper over existing wallpaper? Yes, but it’s generally not recommended. Removing the old wallpaper and starting with a clean surface is the best practice.
  2. What should I do if I encounter air bubbles under the wallpaper? Gently lift the wallpaper and smooth out the air bubbles with a wallpaper smoother.
  3. Is it possible to reposition wallpaper once it’s already on the wall? It can be challenging, but some wallpapers allow for repositioning if done carefully shortly after application.
  4. How do I calculate the amount of wallpaper I need for a room? Measure the height and width of the walls you plan to wallpaper and consult the wallpaper manufacturer’s guidelines for coverage.
  5. Can I wallpaper over textured walls? It’s possible, but smooth walls provide the best results. You may need to apply a wallpaper liner or smooth the textured surface.

In conclusion

Wallpapering can be a fun and rewarding DIY project when done correctly. By avoiding these common mistakes and following proper techniques, you can achieve stunning results that enhance the beauty of your home. Remember to take your time, choose the right wallpaper, and prepare your walls diligently. Happy wallpapering!

Aachieving a successful wallpaper installation involves proper preparation, precise measurements, following manufacturer instructions, and paying attention to detail. By avoiding these common mistakes, you can enjoy a beautifully wallpapered room that enhances the aesthetics of your home.

Choosing the Wrong Wallpaper

One of the most prevalent mistakes in wallpaper installation is selecting the wrong type of wallpaper for your space. Each room has its unique needs, and the wallpaper you choose should align with its purpose. For instance, vinyl wallpaper works well in high-moisture areas like bathrooms and kitchens, while delicate, decorative wallpaper is more suitable for low-traffic areas like bedrooms. Always consider the room’s function and the durability of the wallpaper before making your choice.

Neglecting Wall Preparation

Proper wall preparation is often underestimated but is crucial for a successful wallpaper installation. Skipping this step can lead to issues like peeling or bubbling. Before applying wallpaper, ensure that your walls are clean, dry, and free of imperfections. Fill any cracks or holes, sand the surface for smoothness, and apply a suitable primer. A well-prepared wall will help the wallpaper adhere securely and look flawless.

Misaligning Patterns

If you’re using patterned wallpaper, aligning the patterns correctly is essential for a polished look. Misaligned patterns can make your walls appear messy and unprofessional. Take your time during installation to match the patterns precisely at the seams. This attention to detail will ensure a visually pleasing and cohesive appearance.

Using the Wrong Tools and Materials

Having the right tools and materials is crucial for a successful wallpaper installation. Using subpar adhesive, for instance, can result in poor adhesion, causing the wallpaper to peel or lift over time. Invest in quality wallpaper paste and ensure you have essential tools like a wallpaper smoother and a utility knife. These tools will make the installation process smoother and lead to better results.

Rushing the Installation

Wallpaper installation is not a task to be rushed. Impatience can lead to various issues, such as wrinkles, air bubbles, and uneven seams. Take your time to apply the wallpaper meticulously, starting from the top and working your way down. Smooth out the paper as you go, removing any air bubbles. Avoid cutting corners or trying to finish the job hastily, as it can compromise the overall appearance of your wallpapered walls.

In conclusion, successful wallpaper installation requires careful planning, patience, and attention to detail. By avoiding these common mistakes and following proper techniques, you can ensure that your wallpaper project enhances the aesthetics of your space and lasts for years to come. Remember to choose the right wallpaper, prepare your walls thoroughly, align patterns precisely, use the appropriate tools and materials, and take your time during installation for the best results.
