Hanging panoramic wallpaper is often perceived as a technical challenge reserved for professional decorators. However, with the advent of high-quality non-woven backings and precise digital printing techniques, transforming a room into an immersive mural has become an accessible and rewarding DIY project. At Sunshinewall, we believe that every wall is a blank canvas that deserves perfect execution.
In this comprehensive guide of over 2,000 words, we'll break down every micro-step of the process: from analyzing the moisture content of your wall to the invisible finishing of the joints, including managing complex obstacles like radiators or electrical outlets. Get your tools ready, we're going to turn you into an expert in installing giant wall murals .
1. Understanding the substrate: Why non-woven wallpaper makes all the difference
Before you get out the glue, it's crucial to understand the science behind your non-woven panoramic wallpaper . Unlike traditional wallpaper (also known as "duplex wallpaper"), non-woven wallpaper is a mixture of compressed textile fibers and cellulose.
1.1. The advantage of dimensional stability
The installer's biggest enemy is shrinkage upon drying. Non-woven wallpaper doesn't stretch when wet and doesn't shrink when dry. This means that if your seams are perfect when you install it, they'll stay perfect for years. Learn more about our materials .
1.2. The wall gluing technique
No more bulky wallpaper pasting tables taking up all the space in the living room! With non-woven wallpaper, the paste is applied directly to the wall. This allows you to handle the wallpaper strip dry, making pattern adjustments much more precise and clean.
2. The critical phase: Preparing the wall and the environment
80% of the success of a panoramic wall mural is determined even before the first roll is opened. A poorly prepared wall will ruin the adhesion and flatness of the design.
2.1. Cleaning and smoothing
Your wall must be sound, dry, clean, and smooth. If you have cracks, use a filler first, then a smoothing compound. A grain of sand behind a light-colored panoramic wall will look like a mountain. Sand carefully with fine-grit sandpaper (180 or 240) after the plaster has dried.
2.2. Porosity and background impression
A wall that's too absorbent (new plasterboard) will soak up the adhesive too quickly, making it difficult to slide the wallpaper strip. A non-porous wall (glossy paint) will prevent the adhesive from setting. Expert tip: Always apply a coat of white matte acrylic primer. This evens out the porosity and ensures that the colors of the mural won't be affected by stains on the wall.
3. Essential equipment for a panoramic installer
For a professional result, don't skimp on the tools:
- The plumb line or laser level: Without it, your jungle or mountains will lean, and the error will increase with each strip.
- The smoothing brush: Soft so as not to scratch the digital print.
- Snap-off blade cutter: Change the blade every two or three strips. A dull blade will tear the wet paper.
- The upholsterer's roller: To flatten the joints and make them invisible.
4. Step by step: Installing the first strip to the last
4.1. The starting line layout
Never rely on the angle of a wall; they are rarely perfectly straight. Draw a perfectly vertical line 50 cm from the angle (for a 50 cm wide strip). This allows you to leave a slight excess of 1 or 2 cm extending into the angle, which you will then trim.
4.2. Generous gluing
Use a medium-pile roller. Apply paste to an area slightly larger than the strip (approximately 60 cm for a 50 cm strip). Don't be afraid to use plenty of paste, but avoid dabs.
4.3. Strategic Covering
Position the strip at the top, leaving a 2 cm margin at the ceiling. Unroll it gently. Smooth it down from the center outwards and from top to bottom. Tip: If you see a bubble, don't push too hard; peel the strip back up to the bubble and reposition it.
5. Obstacle management: Sockets, switches and radiators
This is where the stress often mounts. For electrical outlets: 1. Turn off the power. 2. Remove the covers. 3. Place the paper over them. 4. Make a cross-shaped cut in the center of the box. 5. Trim the excess before replacing the cover.

7. FAQ: The questions that save your construction project
What should I do if glue spills onto the design?
Don't panic! Take a clean sponge and some clean water immediately. Dab gently without rubbing vigorously. Our inks are resistant but don't react well to abrasion when wet.
Why do my joints open up when they dry?
This is often due to excessively high room temperatures (overheating) or drafts. Close the windows and turn off the heating during installation and for the following 24 hours to allow for slow, natural drying.
Conclusion: Admire your masterpiece
Once the last strip is in place and the excess trimmed, take a step back. You've transformed the architecture of your room. Hanging panoramic wallpaper isn't just a technical task; it's the culmination of your creative vision.
