Wallpaper is back—and for good reason. It adds texture, depth, and personality in a way paint can’t. But it’s also unforgiving: one misaligned pattern or bubbled seam can ruin the look. Here’s how to get it right.
The wall must be perfect first
Wallpaper magnifies imperfections even more than paint. Before hanging, we make sure the surface is:
-
Smooth and clean
-
Properly filled and sanded
-
Free from flaking paint
-
Primed if needed (especially for fresh plaster or patched areas)
If the wall isn’t prepared, even expensive wallpaper won’t sit properly.
Pattern matching is the make-or-break step
The biggest difference between DIY and professional hanging is pattern alignment:
-
Large prints need accurate measuring and consistent plumb lines
-
Repeats must be matched at seams
-
Corners need special handling so patterns don’t “drift”
We plan the layout so focal points (like chimneys or feature walls) look intentional, not accidental.
The right paste (and timing) matters
Different wallpapers need different adhesives and soaking times. Some papers need “booking” (letting paste absorb before hanging), while others are paste-the-wall. Using the wrong method can cause:
-
Peeling seams
-
Shrinkage gaps
-
Blisters and bubbles
Corners, sockets, and trims are detail zones
Crisp corners and neat cuts around sockets are where wallpapering looks premium. We take the time to:
-
Cut cleanly around outlets and switches
-
Wrap edges properly at windows and doors
-
Create smooth joins without visible overlap
Feature wall or full room?
If you want impact without committing to all four walls, a feature wall is a smart move. For smaller rooms, a lighter pattern can keep things airy while still adding character.
