The Real Reason Your Wallpaper Is Bubbling (And How to Fix It for Good)
Published March 2026 - Joseph Assise III Painting & Wallpapering, Easton PA
You paid good money for that wallpaper. The installer hung it and it looked perfect. Two weeks later the bubbles showed up.
This is one of the most common calls we get from homeowners across the Lehigh Valley. And almost every time, the cause is the same: bad prep work before the paper ever went up.
Here is what actually causes wallpaper to bubble, peel, and fail - and what a properly trained professional does differently.
Cause 1: No Primer or the Wrong Primer
Drywall is porous. When wallpaper paste goes directly onto bare or flat-painted drywall, moisture from the paste gets absorbed unevenly. Some sections grip. Others lift. The result is bubbles, especially along seams and at the top of each strip.
The fix is applying a dedicated wallpaper primer like the products Sherwin-Williams recommends before any paper goes up. It seals the wall surface, creates a consistent surface for adhesive, and makes future removal possible without destroying the drywall underneath.
Every wallpaper project we take on starts with proper wall prep. That means skim coating imperfections, sanding, and applying the right primer for the wall type and paper weight. See how our full wallpaper installation process works.
Cause 2: Wrong Adhesive for the Paper Type
Grasscloth, peel-and-stick, pre-pasted, non-woven, traditional vinyl - these are not interchangeable. Each requires a different adhesive with a different dry time and working time. Non-woven papers, the most common type in today's market, require paste applied to the wall rather than the paper. Traditional papers need paste on the paper and a booking time to let the material relax before hanging.
Getting this wrong is not fixable after the fact without full removal and reinstall.
Cause 3: Trapped Air During Hanging
Bubbles that appear in the first 48 hours are often trapped air. A trained installer works from the center of each strip outward using a smoother to push air to the edges. Large format papers and heavy wallcoverings require more pressure and careful attention at the seams.
Bubbles that appear after more than a week are almost always adhesive or prep failures, not air.
When It Is Time to Start Over
If your wallpaper has been failing for years - lifting at corners, peeling at seams, staining through - the right move is professional removal before anything new goes up. We use a process that protects your drywall and leaves a surface ready for new paper or paint.
We have removed wallpaper in homes across Easton, Bethlehem, and Nazareth - 1920s plaster to modern drywall. Each situation is different. Each requires a specific approach.
Wallpaper bubbling is a craftsmanship and prep problem. Hire someone who knows the difference between a strippable non-woven and a traditional paper. Hire someone who preps the wall before a single strip goes up.
