Wall preparation & Installation

Proper surface preparation is important for the best adhesion and finished appearance of our wallpapers and wall murals.

Textured Walls

Our products are designed for smooth, flat surfaces. Wall texture can affect both adhesion and the finished appearance of wallpaper, murals and wall decals.

Step-by-Step Installation – Overlap & Double Cut Method

1. Apply Adhesive (For Non-Adhesive Wallpaper/Murals).  Spread paste evenly across the area slightly wider than your first panel’s width. For peel-and-stick, skip this step and peel the backing to expose the adhesive.

2. Hang the First Panel. Align the first panel with your vertical guideline. Distribute the total 2-inch (approximately 5 cm) height allowance between the top and bottom—about 1 inch (2.5 cm) at each when centered. Keep enough excess at both edges to cover uneven ceilings or floors. Smooth from the center outward to remove air bubbles.

3. Hang the Second Panel with Overlap. Apply the next panel using the method for your selected material. Overlap the adjoining panel by 2 inches (approximately 5 cm), matching the duplicated artwork. This seam allowance is supplied separately from the outer-edge trimming allowance. Smooth the panel and check alignment before double-cutting the seam.

4. Overlap Corners and Obstacles. For inside corners, overlap mural seams by at least 1 inch. For edge corners, overlap by a full inch and trim for a snug fit. Make relief cuts at sockets, windows, doors, and corners. This helps the mural lie flat and keeps the pattern continuous.

5. Double Cut the Overlap. After positioning the panels and letting the glue set, take a straight edge and a sharp utility knife. Cut through both layers in the middle of the overlap, about 2.5 cm (1 inch) from each panel edge. Remove the cut ‘waste’ from both panels, leaving a perfectly matched seam. Press the edge back into place, adding glue if needed.

6. Trim Edges and Finish. Trim excess wallpaper or mural material along the top, bottom, and sides. Use a sharp blade to make it flush with ceilings, baseboards, and corners. Wipe away glue residue immediately with a damp cloth or baby wipe to avoid visible marks.

7. Smooth and Inspect. Work along all seams with your smoothing tool to remove any bubbles and ensure tight bonding. Adjust any misalignment before adhesive has fully dried. Check all edges and trims for a flawless finish.
