How to Fix Wallpaper Bubbles

What Causes Wallpaper Bubbles?

Three things explain nearly all of them. The first is trapped air during the install, the pockets you get when a strip isn't smoothed well from the center out, common on a rushed or careless hang. The second is too much paste, which leaves a wet pocket that dries unevenly and pools into a visible bump. ROMAN Decorating Products, in its "How to Fix Wallpaper Bubbles" guide, offers a quick tell: "If the bubble is still wet, it's a good indication too much paste was applied." The third is a wall-surface problem, like uneven primer, dust, or moisture caught under the paper before the glue set, which is less common but harder to reach since the cause sits between the paper and the wall.

A few rarer culprits round it out: paste that set before the strip got smoothed (most often with pre-pasted paper left too long after wetting), humidity swings that shrink the paper in one spot and stretch it in another into a wrinkle, a newer house still settling, and, rarely, drywall paper lifting under vinyl when the wall was never sealed with an oil-based primer.

Do Wallpaper Bubbles Go Away on Their Own?

Sometimes, yes. A small fresh one, under an inch and caught within a day of hanging, will often sort itself out. The paste cures, pulls the paper down flat, and squeezes that little pocket of air out at the edges. Wait too long, though, and the window closes. Past 48 to 72 hours, a bubble that's still standing isn't going anywhere on its own. And it only gets worse from there, because the glue around it hardens and locks the shape in for good.

So if you spot small bubbles right after hanging, give it 48 hours before touching anything. Plenty will smooth themselves out, and you only need to fix the ones still standing once the paste has fully cured.

Maker Guidance on Smoothing Out Bubbles

Most peel-and-stick makers expect a few bubbles on a first install and offer quick fixes for them. The Tempaper "Installation Guide" puts it plainly: "Working around corners and smoothing out bubbles is a breeze with our step by step instructions." A smoothing tool and a steady hand clear nearly every air pocket caught during the hang. The ones you find days later are what need the syringe-and-glue method below.

How to Get Rid of Small Air Bubbles in Wallpaper

For anything under 2 inches, the syringe method is the cleanest route. You'll want a craft syringe with no needle (or a dedicated bubble syringe, plus a pin to vent very small ones first), some paste or seam adhesive, a sharp utility knife, a plastic smoother or credit card, and a damp cloth for cleanup.

Start by cutting a small slit in the bubble, following a pattern line where you can, since a vertical cut hides better than a flat one and only needs to be wide enough for the syringe tip. If the bubble is still wet, that's the paste-related kind, so press the excess out through the slit with a finger and wipe it clean before you go further. Then load the syringe, slide the tip toward the middle, and inject just a thin coat of glue, resisting any urge to overfill. Now press the bubble flat with the smoother, working from the outside in toward the slit so any extra squeezes out, and wipe that off the face with a damp cloth to keep the paper clean. Press it once more, and leave it a full 24 hours to dry.

The slit disappears once the glue dries and the paper settles, and the method works on both traditional and vinyl peel-and-stick. One shortcut: since peel-and-stick uses a pressure-sensitive backing rather than wet paste, you can usually skip the syringe entirely and just slit, press the air out, and smooth flat. And if a repair ever goes badly enough that you want to start over, a wallpaper remover gel softens the paste enough to lift the strip cleanly.

How to Remove Large Wallpaper Bubbles

Past 2 inches, a syringe can't spread glue far enough, so switch to the cut-and-repaste method. Cut along two sides of the bubble in an L or T shape, following pattern lines where you can, to free up a flap you can lift off the wall. Ease that flap back gently, without tearing or stretching the paper, and brush fresh paste onto the wall behind it. Then press the flap down again, smoothing from the center out to drive the air toward the cut edges, wipe away any squeeze-out with a damp cloth, and leave it flat for 24 hours to set.

A large bubble in a bright, conspicuous spot may be worth handing to a pro if the cut would show, and badly damaged areas can be patched with leftover paper from a saved roll.

How to Fix Air Bubbles in Peel-and-Stick Wallpaper

Peel-and-stick behaves differently, because the glue is pressure-sensitive with no wet paste involved, so its bubbles are almost always just trapped air. Start by smoothing firmly with a plastic tool, long strokes from the center out, since most release under steady pressure. If that won't do it, peel the affected section back, but not from too far away or you'll lose the bond on the good areas around it, then re-apply and smooth the air out the edge. For a stubborn one on older peel-and-stick, slit it along a pattern line and warm it with a hair dryer on low for a moment, which softens the glue and lets the air escape.

Peel-and-stick is most prone to bubbling when the install rushes the smoothing pass or skips wall prep, and good technique presses the air out before the bond sets. Our How to Apply Peel and Stick Wallpaper guide covers the method that heads them off in the first place.

How to Fix Lifted Seams

A lifted seam is a cousin of the bubble, sitting at the edge where two strips meet rather than mid-strip. Brush seam adhesive under the lifted edge, covering the wall behind it fully, then press the seam down with a seam roller or clean cloth, working from the inside out. Wipe the excess off the edge with a damp cloth and let it dry 24 hours. Seam adhesive is built for re-bonding edges, so it holds better than ordinary paste here, dries clear, and stays put.

How to Prevent Wallpaper Bubbles

Since most bubbles are really install issues, a few habits head them off. Smooth from the center of each strip outward rather than edge to edge, which pushes the air to the edges where it can escape. Use a plastic smoother or a wallpaper brush instead of your hand, because hands miss the small pockets. Go easy on the paste, since the roll's label gives the right amount and extra just makes wet pockets. With pre-pasted paper, respect the soak time, because over-soaked paper pockets and under-soaked paper bonds weakly and bubbles. Prime the wall well so it bonds evenly everywhere, give that primer its full cure (usually 24 hours) so you don't trap moisture, and clean the wall first, since dust and grit under the paper turn into local bubbles and weak spots.

When to Call a Pro

Most of these repairs are easy DIY work, but a few cases earn a call. Lots of bubbles or wide bubbling points to a wall or paste problem that needs diagnosing before any patch. Bubbles in pricey hand-printed or grasscloth paper are worth a pro's hands, since a botched repair on premium stock gets expensive fast. Bubbles from water damage mean you fix the moisture source first and the paper second. And a commercial install may have a warranty that requires professional repair.

Frequently Asked Questions

Can you fix bubbled wallpaper?

Yes, in almost every case. A small bubble takes 5 to 10 minutes with a syringe and paste, and a larger one 15 to 30 minutes with the cut-and-repaste method. The tools run under $20.

Do air bubbles go away on wallpaper?

Small fresh ones, under an inch and within a day of hanging, often go on their own as the paste cures. Anything still there past 72 hours needs active work, because it won't vanish by itself.

What causes wallpaper bubbles?

Three main things: trapped air from weak smoothing, too much paste making a wet pocket, and wall-surface issues like dust, moisture, or uneven primer under the paper. Most trace back to one of those.

How do you get rid of wallpaper bubbles?

For a small one, slit it, inject fresh glue with a syringe, and smooth flat. For a large one, cut an L-shaped flap, brush paste behind it, and press it back. For peel-and-stick, smooth firmly with a plastic tool, lifting and re-applying the section if you need to.

How do you prevent wallpaper bubbles?

Smooth from the center out, use a plastic smoother rather than your hand, don't overdo the paste, respect the soak time on pre-pasted paper, prime the wall properly, and clean it before you prime.

Why do bubbles appear in fresh wallpaper installs?

Usually trapped air from a weak smoothing pass, a wet pocket from too much paste, or moisture caught under the paper from uncured primer. Most fresh bubbles on a well-primed wall are just air, and they smooth out within the first day.

Our Take

Bubbles look alarming. They rarely are. Simple tools, a bit of patience, and almost any of them comes good. Two rules carry most of the load. Go easy on a fresh install, because the small ones often vanish inside 48 hours on their own. And deal with an old one before it spreads, because time is on the bubble's side, not yours.

And remember that most bubbles trace back to the hang, not the paper itself. For the install skills that stop them at the source, see our guides on How to Hang Wallpaper and How to Apply Peel and Stick Wallpaper.
