How to Measure Your Wall
Follow our simple guide to ensure a perfect fit. We recommend adding a 5 cm (2 inches) safety margin to your total width and height measurements.
1. Standard Walls
Measure the full width and height of your wall. Double-check your numbers and remember to include your safety margin for a seamless installation.
2. Sloped Walls
Identify the highest and widest points of the wall. Ignore the slopes during measurement; we will print a full rectangle to be trimmed on-site.
3. Multi-Sloped Walls
Measure the maximum height and width. Like single slopes, the wallpaper is delivered as a complete graphic that you trim to fit the angles.
4. Windows & Doors
Measure the entire wall surface as if there were no obstacles. Do not subtract the area of doors or windows to ensure pattern continuity.
5. Multiple Walls
Combine the widths of all connecting walls. Measure the height from the highest point and treat the entire surface as one continuous piece.
6. Staircases
Measure the vertical distance between the highest and lowest points. Treat the sloped section as a standard rectangle for printing purposes.
Hanging Instructions
- ✔ Panels are numbered in hanging order
- ✔ Installation should go from left to right

Preparation
1. Surface Check
Walls must be clean, dry, and smooth. Remove any old wallpaper or flaking paint. If your wall is highly porous (new plaster), apply a primer coat first to ensure the best adhesion.
2. Mix Wallpaper Paste
Use a high-quality adhesive designed for non-woven materials. Mix thoroughly with water until you achieve a consistent, thick paste. Let it rest for 5 minutes before application.
Hanging
1. Organize Panels
Verify all panels before starting. They are numbered at the top to guide your sequence. Lay them out to ensure the design flow is correct from left to right.
Installation
2. Set the First Panel
This is the most important step. Use your spirit level to mark a perfectly straight vertical line 50 cm from your starting point. Align your first panel exactly to this line.
3. Apply Paste to Wall
Apply the paste directly to the wall using your roller. Cover an area slightly wider than the panel you are about to hang to ensure the edges stick perfectly.
4. Seamless Alignment
Press panels together tightly at the seams without overlapping. Use your wallpaper brush to smooth out bubbles, working from the center toward the edges.
5. Finishing Touches
Trim excess paper at the ceiling and floor using a sharp utility knife and trim guide. Clean any excess paste with a damp sponge and allow 24 hours to dry.
Peel & Stick Guide
Our self-adhesive wallpaper is designed for a mess-free transformation. No extra glue needed—simply peel the backing and apply to your wall for an instant new look.
Required Tools
Spirit Level
Ruler
Pencil
Utility Knife
Wallpaper Brush
Soft Squeegee
Preparation
1. Clean Your Wall
Use a damp cloth with mild soap to wipe down the surface. Ensure the wall is completely dry, smooth, and free of dust. For freshly painted walls, wait at least 4 weeks before installation to allow the paint to fully cure.
2. Acclimate the Panels
Unroll your panels and let them lay flat in the room where they will be installed for at least 24 hours. This allows the material to adjust to the room's temperature and humidity.
3. Organize Your Layout
Check all panels for any defects. Each panel is numbered at the top. Arrange them in numerical order to ensure the pattern flows correctly from left to right.
Application
1. The Vertical Guide
Use your spirit level to mark a faint vertical line one panel width from your starting point. This ensures your first panel—and the rest of your wall—is perfectly straight.
2. Peel and Stick
Peel back about 12 inches of the backing paper from the top. Align the panel with your vertical line and smooth it onto the wall. Gradually peel more backing as you work your way down.
3. Remove Bubbles
Use a soft squeegee or wallpaper brush to remove air bubbles. Work from the center of the panel outwards towards the edges with firm, even strokes to ensure strong adhesion.
4. Final Trimming
Once all panels are edge-to-edge (no overlapping), use a sharp utility knife and a ruler to trim the excess material along the ceiling and floor for a clean finish.
