Most mural failures are hanging failures, not printing failures. An afternoon, two people and a level will get you a result you would pay an installer for — provided you do the boring preparation first.
| Tool | What it is for |
|---|---|
| Level or laser level | Your one true vertical line. Do not trust the corner of the room — corners are never plumb. |
| Plastic smoother | Pushing air out. A plastic wallpaper smoother, not a squeegee with a hard edge. |
| Sharp blade + fresh snap-offs | A dull blade drags and tears. Snap a new edge for every few cuts. |
| Broad knife / taping knife | A straight edge to cut against at the ceiling and skirting. |
| Step ladder, sponge, soft cloth | Obvious, but people start without them. |
Repositionable while you work. If a panel goes on crooked, peel it back gently and re-lay it — you have several attempts before the adhesive tires. Bubbles that stay after smoothing can be pricked with a pin and pushed flat. Not suitable for textured walls or paint under 30 days old.
Wet the back with a sponge or a water tray for the time on the instructions — usually 30 seconds — then book it: fold the panel gently pasted-side to pasted-side and let it rest 2–3 minutes. Booking lets the paste activate and the material relax to its final size, and skipping it is why seams open up a week later. Hang butt-jointed rather than overlapped if you are confident.
Heavier, less forgiving, and specified with its own adhesive. Double-cut the seams: overlap the two panels, cut through both with a straight edge, remove both waste strips, and roll the joint. In an occupied building this is a job for an installer — and at that weight, we would rather it was ours.
| Problem | Cause | Fix |
|---|---|---|
| Edges lifting after a day | Dust, uncured paint, or a wall washed with something oily | Clean and re-press. If the paint is the problem, it will keep happening — the wall needs priming. |
| Bubbles you cannot push out | Smoothed side to side instead of centre-out | Peel back to the bubble and re-lay that section. |
| Seam gap appearing | Prepasted hung without booking, or the room is very dry | Re-wet the edge and roll it. Book properly on the remaining panels. |
| Pattern not matching at the seam | First panel was not hung plumb | Nothing downstream fixes this. Re-hang from panel 1 against a fresh level line. |
| Torn edge at the ceiling | Dull blade | New blade, every few cuts. Blades are cheaper than panels. |

Estimate includes material, printing and panel layout. Add two inches to each wall dimension for trim allowance. Nothing prints until you approve a proof. How to measure →
