Common mistakes when wallpapering (and how to avoid them)

Wallpaper can completely transform an interior from calm and refined to bold and expressive. But precisely because a wall has such an impact, a small mistake during wallpapering can affect the final result. Fortunately, most problems are easily preventable. Below, you'll find the most common wallpapering mistakes, along with practical tips for a sleek, stylish result.

Not preparing the surface properly

One of the biggest mistakes is starting to wallpaper without properly preparing the wall. Imperfections, old paint residue, grease, or dust can remain visible and prevent wallpaper from adhering properly. Especially with luxurious wallpaper or delicate textures, you want a perfect base.

How to prevent this:
Make sure the wall is clean, dry, smooth, and even . Fill holes and cracks, sand where necessary, and degrease the wall (especially in kitchen-like areas). Is the wall absorbent or powdery? Always use a primer for even adhesion. A good base is the fastest way to a luxurious look. Newly plastered wall? Always prime it first to eliminate the absorbency.

Choosing the wrong wallpaper for the room

Not every wallpaper is suitable for every room. In damp or heavily used areas, a less suitable material can wear out, discolor, or peel off more quickly. Therefore, the choice isn't just about the design, but also about how you use the space.

How to prevent this:
Choose wallpaper based on two factors: practicality and ambiance. In a busy household or a space where people live, a more durable and easy-care wallpaper is often the best choice. In quieter spaces, you can choose more based on texture, luxury, and ambiance. At Selected Wallpapers, design and quality always go hand in hand, so you don't have to choose between beautiful and practical.

Insufficient attention to pattern and direction

Patterned wallpaper requires precision. A pattern that doesn't quite flow, a strip that's the wrong way around, or a misaligned first strip can quickly create a cluttered, messy look, which is a waste of design. Make sure your pattern is positioned neatly and centered on the wall.

How to prevent this:
Check the pattern layout and direction beforehand (sometimes there's an arrow on the back). Mark a perpendicular line on the wall where necessary, and take your time with the first strip: it will determine the rest. Re-measure each strip and work consistently to ensure the design is fully realized.

Using too little or the wrong glue

Too little adhesive can lead to peeling seams and edges. Using the wrong adhesive can affect adhesion, durability, and even appearance—especially with heavier wallpaper or special materials.

How to prevent this:
Always use adhesive suitable for the type of wallpaper. For non-woven wallpaper, apply the adhesive directly to the wall: evenly, sufficiently, and at the correct thickness. Work carefully so the wall doesn't exceed its open time. This prevents air bubbles, peeling edges, and a less smooth final appearance.

Not taking light and space into account

Wallpaper can look completely different in daylight than it does in the evening under artificial light. A busy pattern can also visually shrink a small room, while a subtle texture can add space and luxury.

How to prevent this:
Always view wallpaper in the room itself and pay attention to the light and shadows. In smaller rooms, light shades and subtle textures often work best. Large prints can be stunning, but are often most effective as an accent wall—especially if you want to keep the room visually balanced.

Wanting to work too fast

Wallpapering requires attention and precision. Haste often leads to uneven lines, air bubbles, damage, or visible seams. The difference between "neat" and "perfect" usually lies in calmness and control.

How to prevent this:
Take your time and work step by step. Use the right tools (wallpaper spatula, sharp knife, spirit level/plumb line) and check each section before continuing. Press edges gently, remove air bubbles immediately, and only cut cleanly when everything is in place.

Carefree wallpapering starts with the right choice

A perfect end result starts with thorough preparation—and with wallpaper that suits your space, your style, and your daily use. At Selected Wallpapers, you'll find carefully curated designs that are not only visually appealing but also excel in quality and ease of use.
