Installing wallpaper around windows, doors, and tricky corners might seem intimidating, but with the right tools and a few clever tricks, you can achieve a clean, professional result with ease.

What You’ll Need:

A sharp trimming knife or utility cutter is essential – don’t start without it! Precision is the key when working around detailed edges.

Prepare the Adhesive

Mix the paste as described in our main guide. Use a brush to carefully apply glue around door and window frames, getting as close to the edges as possible. Wipe off any excess glue from the frame immediately to avoid staining.

Position Before You Cut

Before making any cuts, align the wallpaper to match the pattern properly. Start from the top of the wall, near the ceiling, and smooth the strip downward toward the frame.

Precision Cutting

Identify where the top corner of the door frame or window reveal meets the wall. Using your knife, cut a 45-degree angle from the corner toward the edge of the wallpaper. This will allow you to snugly press the paper into the corner and along the edge of the frame.

Trim the Edges Cleanly

Once in place, carefully trim along the window or door frame using your knife. Clean your blade regularly during the process to prevent glue build-up, which can tear the wallpaper or leave smudges.

Final Touches

Repeat the same technique around each edge. Use a damp sponge to wipe off any excess glue immediately—never let it dry on the surface, as this might cause irremediable stain damages!

Choose the Method That Works Best for You

There’s more than one way to wallpaper around switches and sockets—you can either remove the cover plates or wallpaper around them. There’s no right or wrong method here, just pick the one you feel most comfortable with.

Method A – Removing the Cover Plate

1. Turn off the power, then carefully remove the faceplate of the light switch or socket.
2. Position the wallpaper strip directly over the outlet.
3. Using scissors or a craft knife, make a small X-shaped cut over the outlet area.
4. Trim the opening slightly smaller than the socket/switch to ensure a clean finish once the cover is back on.
5. Smooth the wallpaper into place, press it gently around the opening.
6. Reattach the faceplate for a neat, professional look

Method B – Wallpapering Around the Outlet

1. Turn off the power, then slightly loosen the screws of the cover plate, allowing it to lift a little from the wall.
2. Hang the wallpaper strip over the socket area and mark its location.
3. Cut a small hole in the center of the marked spot, then snip outwards in an X-shape using scissors.
4. Gently press the wallpaper around the edges of the socket.
5. Carefully trim around the shape to match the outlet.
6. Tuck the wallpaper edges slightly under the plate, then tighten the screws back in place for a tidy finish.

Whichever method you choose, your walls will look smooth and stylish. With a little care and precision, your wallpaper will look flawless—even around the details.

Helpful Tips for Perfect Results

When you’re wallpapering more than one wall, a common question is: how do I handle the corners? Here are a few useful tips to help you get a smooth and professional finish.

• Corners Aren’t Always Perfect
  Most corners aren’t exactly 90 degrees, which can make wallpapering a bit tricky. If you need to fill or smooth the wall beforehand, try to create as straight and sharp a corner as possible. Using a corner bead or corner protector during prep work can help you achieve a cleaner angle and make wallpapering much easier later.
• Order with Extra Margin
  When ordering mural wallpaper, we always recommend adding an extra 5 cm (2 inches) to both the height and width of your wall measurements. This gives you a safety margin—especially useful in uneven corners—so you can fully cover the surface without gaps or misalignment.

Well-prepared corners are the key to a flawless wallpaper installation. With a little planning, even tricky angles can look seamless!

Step-by-step guide for flawless corner work

Wallpapering inside corners can feel tricky, but with the right technique, you’ll get a clean and seamless result. Here’s how:

1. Measure and Cut Precisely
   Start by measuring the distance from the edge of the previous strip to the corner. Then add about 2 cm (around ¾ inch) to this measurement. Use this to cut your next strip of wallpaper.
2. Apply Adhesive
   Use a brush to apply adhesive carefully into the corner area. Make sure the glue is spread evenly to prevent bubbles and ensure strong adhesion.
3. Smooth into Place
   Carefully place the strip into position, pressing it into the corner. Use a rubber roller or wallpaper smoother to remove any air bubbles, starting from the center and working outwards.
4. Start the Next Wall Cleanly
   Before placing the next strip after the corner, check for vertical alignment. Most corners aren’t perfectly straight, which means your strip might not sit perfectly flush. In this case, slightly overlap the corner strip to maintain a straight and clean line across the next wall.

Pro tip: Don’t aim for perfection in the corner—aim for alignment across the rest of the wall. That’s where your eye will naturally go!

Tips for achieving a clean and durable finish

When wallpapering around outside corners, precision is key to getting a professional look that lasts. Here’s how to tackle both straight and uneven corners with confidence:

Straight Corners

1. For a clean finish, always ensure your wallpaper strip wraps around the corner by at least 2 cm (about ¾ inch). If it ends right at the edge, there’s a high risk it won’t adhere properly or may start peeling over time.
2. Apply the strip as usual, letting it extend slightly around the corner.
3. The next strip should be placed directly beside the previous one, without overlapping, to maintain a seamless look.

Uneven Corners

Walls are rarely perfect, and uneven corners can cause alignment issues. Here’s how to handle them:

1. Measure the distance from the last strip to the corner and add about 2 cm.
2. Cut the next strip based on this measurement.
3. Use a brush to apply glue carefully into the corner area.
4. Place the strip on the wall, allowing 1.5–2 cm to wrap around the corner.
5. Before placing the next strip, check vertical alignment carefully.
6. Ideally, place strips edge-to-edge. However, if the wall is uneven, a slight overlap at the corner may be necessary to compensate and keep your pattern straight.

Pro tip: If you’re dealing with tricky corners, extra glue and a steady hand go a long way in keeping everything secure and aligned.
