How to Install Wall Murals and Wallpaper
This guide covers how to install Decor2Go wall murals and wallpaper. Watch the video first, then follow the quick steps below for your wall type. Good prep and a straight starting line are what make the finish look professional.
Installation steps
- Clean the wall (dust and grease cause lifting)
- Patch, sand, and smooth imperfections, let everything fully dry
- Remove outlet and switch plates, protect floors
- Mark a straight vertical reference line with a level
- Use sharp blades for trimming, change blades often
- Lay panels out in order before you begin
- Start on your straight reference line
- Smooth from the center outward as you place each panel
- Align seams carefully, then trim top, bottom, and edges once set
- Hang the first drop perfectly straight using your reference line
- Apply adhesive using the instructions included with your order
- Match seams and patterns as you go, avoid stretching the paper
- Trim cleanly at ceiling and baseboards with a sharp blade
- For estimating quantity, use our roll calculator during ordering (especially when patterns need matching)
- Plan where your first drop starts so the pattern lands nicely in the room
- Dry align the next length before it goes up, then commit
- If the match is off, fix it early; it is harder once the adhesive sets.
- Bubbles: smooth gently from the center out
- Seams lifting: check wall prep and adhesive coverage, press lightly
- Pattern drifting: pause and realign, do not force the seam
- Ragged trims: switch to a fresh blade

Do I need to prime the wall?
If the wall is porous, chalky, freshly patched, or unevenly painted, primer helps create a more reliable surface and a cleaner finish. On solid, well painted walls, it is often optional.
Can I install over textured walls?
Can I install over textured walls?
Light texture can sometimes work, heavy texture usually shows through and can cause poor adhesion. Smoothing the surface first is the safest path for a premium result.
How do I make sure the first drop goes on straight?
How do I make sure the first drop goes on straight?
Use a level to draw a straight vertical reference line, then align your first panel or first drop to that line. Do not follow the corner, corners are rarely perfectly straight.
How do I cut around outlets and switches?
How do I cut around outlets and switches?
Turn off power, remove cover plates, hang over the opening, then make small relief cuts and trim carefully. Reinstall cover plates after the wallpaper is set.
How do I handle inside and outside corners?
How do I handle inside and outside corners?
Inside corners, keep it neat and do not stretch the material; overlap slightly only if needed for alignment. Outside corners, avoid forcing a single piece around the corner; clean cuts and careful alignment reduce lifting risk.
What is the best way to avoid bubbles and wrinkles?
What is the best way to avoid bubbles and wrinkles?
Work from the center outward with steady, light pressure. Keep your hands and tools clean, and avoid stretching while smoothing.
What if I see bubbles after it is up?
What if I see bubbles after it is up?
Small bubbles often relax as the adhesive sets. If a bubble persists, gently lift and resmooth if possible, or carefully work air out toward the nearest edge with light pressure.
What if a seam is lifting?
What if a seam is lifting?
Seams usually lift from dust, poor wall prep, or uneven adhesive coverage. Press lightly, clean away any residue, and ensure the seam has even contact without overworking it.
How do I match patterns on wallpaper rolls?

Many wallpapers can be removed, but removal depends on wall prep, paint type, adhesive, and time on the wall. Proper prep at install makes future removal easier and helps protect the wall surface.
