Quick answer
You can wallpaper over textured walls only when the texture is very light. A faint orange peel may work under a thick, forgiving paper, but knockdown, heavy orange peel, and skip-trowel texture will show through and weaken adhesion. The reliable fix is a skim coat to a smooth, Level 5 style finish, then primer. Wallpaper Installer Seattle evaluates texture on site and recommends the right prep.
Key facts
- Wallpaper telegraphs texture: bumps and ridges show through, especially under raking light or with thin, shiny, or dark papers.
- Texture reduces contact area, so paste and peel-and-stick adhesive grip less and seams are more likely to lift.
- Skim coating with joint compound to a Level 5 style finish is the most reliable way to prepare textured drywall.
- Liner paper can bridge minor imperfections but is not a substitute for skim coating moderate or heavy texture.
- Test older textured finishes for asbestos before sanding, and test pre-1978 painted surfaces for lead.
Can you wallpaper over textured walls?
Sometimes, but usually not with good results. Wallpaper conforms to whatever is beneath it, so texture shows through as a bumpy, shadowed surface, and the paste only bonds to the high points.
The answer comes down to three things: how pronounced the texture is, how thick and patterned the wallpaper is, and how the room is lit. A heavy textured vinyl or a busy floral can hide a lot. A smooth metallic, a solid color, or a thin paper in a hallway lit from the side will show nearly everything.
When a client asks us whether their textured walls will work, we look at the wall with a flashlight held flat against it. If the shadows are obvious, the wall needs to be smoothed first.
What kinds of wall texture are common in Seattle-area homes?
Most textured walls around Puget Sound fall into a few familiar types. Many homes and condos built from the 1970s onward have sprayed drywall texture, while older homes are more likely to have plaster that is smooth or hand-troweled.
| Texture | What it looks like | Wallpaper directly over it? | Typical prep |
|---|---|---|---|
| Light orange peel | Fine, even dimples like citrus skin | Possible with thick or heavily patterned paper | Light sand and prime, or a skim coat for thin papers |
| Heavy orange peel | Pronounced bumps you can easily feel | Not recommended | Skim coat, sand, prime |
| Knockdown | Flattened splatter with mesa-like peaks | No; ridges telegraph through | One or two skim coats, sand, prime |
| Skip trowel or hand texture | Irregular troweled patches | No | Skim coat to fill the low areas, sand, prime |
| Popcorn (ceilings) | Coarse, cottage-cheese spray | No | Test for asbestos first, then remove or cover per results |
If you are planning paper on a ceiling, texture is even more of an issue, because ceilings catch light at a low angle. Our ceiling wallpaper ideas and tips covers that in more detail.
Why does texture cause problems for wallpaper?
Texture causes two problems: it shows through, and it weakens the bond. Both get worse over time.
- Show-through. Wallpaper is thin, and light skimming across a wall picks out every peak. Seams also land on ridges in places, which makes them look open or uneven.
- Weak adhesion. Paste only contacts the high points, leaving tiny air pockets in the valleys. Edges and seams are the first to lift, especially in rooms that see humidity swings, like bathrooms during a long, damp Northwest winter.
- Peel-and-stick struggles most. Self-adhesive wallpaper relies entirely on surface contact. On textured walls it often bubbles, sags, or lets go within weeks. Our guide to peel-and-stick vs. traditional wallpaper explains why.
- Harder future removal. Paper anchored on texture tends to tear rather than release, and scraping texture can gouge the drywall.
What is a skim coat, and do you need one?
A skim coat is a thin layer of joint compound troweled over the entire wall to fill texture and create a flat, uniform surface. For moderate or heavy texture, it is the most dependable way to get a professional wallpaper result.
Here is how a typical skim coat goes:
- Test first. If the texture is original to an older home, have it tested for asbestos before sanding. If the walls were painted before 1978, test for lead as well.
- Knock down high points. Scrape or lightly sand sharp peaks so the trowel glides over them.
- Prime if needed. Glossy or chalky surfaces may need a bonding primer so the compound grips.
- Apply the first coat. Spread thinned joint compound with a wide trowel or skimming blade, filling the valleys and leaving a thin film over the peaks.
- Apply a second coat if needed. Knockdown and heavy orange peel usually need two passes, often in different directions.
- Sand and inspect. Sand smooth, then check the wall with a work light held flat against it. Touch up any remaining low spots.
- Prime. Seal the new compound with a wallcovering primer before any paper goes up.
Skim coating is messy and slow to dry, especially in cool, humid weather, so it often adds a day or more to a project. That drying time is part of the schedule, not an optional extra.
What is a Level 5 drywall finish?
A Level 5 finish is the highest level in the drywall industry's finishing scale: the wall is taped and finished like a standard smooth wall, then covered entirely with a thin skim coat so the surface is uniform from edge to edge. It is commonly specified under critical lighting, glossy paints, and wallcoverings that are thin or reflective.
For wallpaper, the idea is the same whether you start with new drywall or old textured walls: one continuous, smooth, evenly porous surface. Lower levels may leave the joint areas smoother than the paper face of the drywall, and that difference can show through thin papers. When we skim textured walls for wallpaper, we aim for that same uniform result.
Can liner paper cover textured walls instead?
Liner paper can smooth over very light texture, hairline cracks, and minor surface flaws, but it will not hide knockdown or heavy orange peel. It is a plain, heavy paper hung before the decorative wallpaper.
Liner paper is often hung horizontally, a technique called cross-lining, so its seams never line up with the vertical seams of the finished paper. It is common under high-end papers, grasscloth, and on older plaster with fine crazing.
- Good fit: light orange peel, slightly uneven plaster, walls with fine cracks, or when the paper manufacturer recommends a liner.
- Poor fit: knockdown, skip trowel, or any texture you can clearly see from across the room.
- Remember: liner paper still needs a primed wall underneath, and it adds material and labor to the job.
Which wallpapers are most forgiving on imperfect walls?
Thicker papers with busy patterns or their own surface texture hide the most. If smoothing the walls is not in the plan, choose materials accordingly, and accept that the result will not be perfectly flat.
- More forgiving: heavy embossed or textured vinyls, thick non-woven papers, and dense all-over patterns.
- Less forgiving: metallics, foils, silks, solid colors, thin pulp papers, and large-scale murals with open backgrounds. Our guide to metallic, silk, and specialty wallpaper explains why these need especially smooth walls.
- Natural fibers: grasscloth is textured itself and hides minor flaws, but it still needs a sound, primed surface.
What primer goes on a skim-coated wall before wallpaper?
A fresh skim coat needs a dedicated wallcovering primer before any paper is hung. Bare joint compound is soft and very porous, so it pulls moisture out of paste too fast and can bond so tightly that future removal tears the surface.
A good wallcovering primer evens out porosity between the compound and any remaining painted areas, gives the installer working time to slide and match each strip, and leaves a surface the paper can release from years later. For thin or light-colored papers and grasscloth, a primer tinted close to the paper's background color keeps seams from flashing white. Our wallcovering primer guide covers how to choose one, including mildew-resistant options for bathrooms.
Should a professional handle textured wall prep?
For most textured walls, yes. Skim coating looks simple but is hard to do evenly, and poor skim work leaves ridges and trowel marks that wallpaper will show just as clearly as the original texture.
Our wall preparation for wallpaper service covers texture smoothing, patching, and priming, and it pairs directly with professional wallpaper installation so one team is responsible for the finished result. Prep is one of the biggest cost factors in any project, and our wallpaper installation cost guide explains how it is estimated.

Frequently asked questions
Can I just sand texture off instead of skim coating?
Light sanding can soften fine orange peel, but sanding rarely flattens knockdown or heavy texture and can cut into the drywall paper. Skim coating fills the low areas instead, which gives a flatter result. Test older texture for asbestos before any sanding.
Will peel-and-stick wallpaper stick to orange peel walls?
It often sticks at first and then lifts at the seams or bubbles in the valleys, because self-adhesive backing needs full contact. Some manufacturers specifically say their product is for smooth walls only. If you love a peel-and-stick pattern, smoothing the wall first gives it the best chance.
How long does a skim coat need to dry before wallpaper?
It depends on how thick the coats are, the compound used, and room temperature and humidity. Each coat typically needs to dry fully before sanding, and the final coat must be dry before priming. Cool, damp weather can stretch drying noticeably, so plan an extra day.
Does every wall in the room need to be skim coated?
Only the walls getting wallpaper need it. For an accent wall, we skim that wall alone and feather the edges at the corners. Just keep in mind that the adjoining painted walls will keep their texture, which is usually fine visually.
Is liner paper cheaper than skim coating?
Not always. Liner paper adds material and a full extra hanging step, and it only works on light texture. For moderate or heavy texture, a skim coat is the right fix regardless of cost, because liner will not hide it.
My condo has knockdown texture. Can wallpaper still work?
Yes, with prep. Knockdown needs to be skim coated smooth and primed before paper goes up. If your building has HOA rules about renovation hours or common-area protection, we plan the dusty sanding steps around those requirements.
