Before you ever choose a pattern, the small print on a wallpaper roll has already decided whether the job calls for a water tray, a bucket of paste or neither. Prepasted, unpasted, non-pasted and peel and stick are four labels for three ways of getting adhesive onto a wall. Anyone asking what is prepasted wallpaper is really asking where the glue lives and what wakes it up, and that same question sorts out every other label on the roll.
What Is Prepasted Wallpaper?
Prepasted wallpaper has a dry adhesive applied to its back during manufacturing. In the roll it does nothing at all. Water switches it on: depending on the maker's instructions, the strip is dipped in a water tray or wetted on the back with a sponge, roller or spray bottle, and the coating turns tacky enough to hold the paper to the wall.
Most prepasted papers are then booked. Booking means folding the wet strip back on itself, pasted side to pasted side, without creasing it, and letting it rest. The rest gives the paste time to activate and lets the paper absorb moisture and relax, because paper swells a little when it gets wet. Hung too soon, it can keep moving on the wall and open up at the seams. How long to soak and how long to book varies from one product line to the next (some prepasted papers skip booking entirely), so the instructions printed with the roll are the only numbers to follow.
Do you need extra paste for prepasted wallpaper?
Usually not, though opinions split. Wallpaper makers generally say water alone is enough, and at least one major maker warns that adding paste makes the paper harder to take down when you redecorate. Adhesive makers, meanwhile, sell activators and thin pastes marketed for extra grip and longer working time. If you are tempted, read the roll's instructions first, since adding paste can change how the paper behaves later.
What Is Unpasted Wallpaper?
Unpasted wallpaper has no adhesive on it at all. You buy the paste separately and apply it during the hang, which gives you control over the adhesive and adds a pasting step that prepasted paper does not have. Many papers at the decorative end of the market ship this way, including a lot of grasscloth and other natural-fiber coverings, though that is a tendency rather than a rule.
Unpasted papers come in two working methods, and the label tells you which one the maker intends:
- Paste-the-paper. Paste is brushed or rolled onto the back of each strip, which is then booked, much like a prepasted strip after wetting.
- Paste-the-wall. Paste goes on the wall and the dry strip is pressed into it straight from the roll. These are often papers with a nonwoven backing, which barely expands when wet, so there is usually no booking step.
Paste-the-wall and nonwoven usually travel together, but they are not quite the same thing. Some nonwoven-backed papers can be hung either way, and some makers still ask for a light dampening, so the label wins over any general rule.
What Does Non-Pasted Wallpaper Mean?
Non-pasted means exactly the same as unpasted: the back of the roll carries no adhesive, and you will need to buy one. The two words are used interchangeably across listings, and some retailers simply call this traditional wallpaper. If a product page says "non-pasted" and you were expecting to wet it and hang it, that is the moment to add a tub of the right paste, and a brush or roller, to your cart.
The quickest way to tell what you have is the label. Many rolls carry a row of small pictograms, and in Europe these symbols are standardized under EN 235, the vocabulary-and-symbols standard for wallcoverings. The three application symbols look like this:
- Prepasted: a trough of water with a strip of paper dipping into it.
- Paste-the-paper: a pasting brush above a strip of paper.
- Paste-the-wall: a pasting brush facing a vertical bar that stands for the wall.
No symbol? Check the listing's specifications, or ask the seller before you buy paste or a water tray. Peel and stick is the easiest to spot, because it has a separate liner covering the adhesive.
Strippable, Peelable, Washable: The Other Words on the Roll
A second set of label terms describes how a pasted paper comes off and how it can be cleaned, not how it goes up. Definitions drift a little between makers and between languages, so read them by what they describe rather than by the word alone.
- Strippable wallpaper is designed to come off the wall dry, strip by strip, in one layer. Most definitions say it should leave little or no residue, though some allow for paste left behind that you then wash off.
- Peelable wallpaper comes off in two layers. The decorative top layer pulls away dry and the backing paper stays on the wall, either to be removed separately or, if the maker allows it, papered over.
- Washable and scrubbable are cleaning grades. Washable generally means the surface can take a damp sponge and mild soap; scrubbable means it can take a soft brush and a cleaning solution. The care symbols use wavy lines for water, with more lines for more washable and a brush added for the scrub grades.
Strippable does not mean peel and stick. It describes how a pasted wallpaper is removed at the end of its life, while peel and stick describes how the paper sticks in the first place. You will find strippable prepasted and strippable unpasted papers alike.
Peel and Stick: The Third Backing
Peel and stick skips water and paste altogether: the adhesive is already active under a release liner, so there is no tray, no bucket and no booking. We cover how that adhesive works, and where it does and does not belong, in our guide to what peel and stick wallpaper is.
What the paper is made of matters too, mostly for how it handles moisture and wear. Our explainer on what vinyl wallpaper is covers how those layers differ.
Which Backing Are WallWear Rolls?
WallWear rolls are peel and stick, so none of the prepasted or unpasted steps above apply to them. The product pages list the core specs as premium water-resistant vinyl, a matte finish, and a 17.5 by 216 inch roll. The installation line is short: "No tools, paste, or soaking required." The rolls are listed as removable and repositionable, with an anti-bubble design that helps trapped air escape as you smooth.
One thing to keep in mind on removal: the product pages note that results can vary with the surface, the paint, the condition of the wall and how long the paper has been up, and they call for a clean, smooth, dry surface to begin with.
If a water-free hang suits your project, the designs range from the blue-gray watercolor texture of Lake Life to the green flowers and leaves on light yellow of Urban Stems, or the quieter gray, nature-inspired texture of Whispering Tales.

Frequently Asked Questions
Is prepasted wallpaper the same as peel and stick?
No. Prepasted wallpaper carries a dry adhesive that only works once you wet it, so you still need water, a tray or sponge, and usually a booking rest before hanging. Peel and stick has an adhesive that is already active under a release liner. You remove the liner and press the paper onto the wall, with no water involved at any stage.
Is non-pasted the same as unpasted wallpaper?
Yes. Non-pasted and unpasted both describe wallpaper with no adhesive on the back, which means you buy paste separately and apply it to the paper or to the wall, depending on what the label specifies. Some retailers call the same product traditional wallpaper. If a listing uses any of these terms, plan on paste and the tools to apply it.
Does strippable wallpaper mean peel and stick?
No. Strippable describes how a pasted wallpaper comes off: it is designed to pull away dry, strip by strip, usually leaving little residue. It says nothing about how the paper was hung, and both prepasted and unpasted papers can be strippable. Peel and stick describes the adhesive itself, which is ready to use under a liner.
How can I tell if wallpaper is prepasted?
Start with the label or listing. Many rolls carry a pictogram of a water trough with a strip dipping into it, and listings usually state prepasted in the specifications. If neither tells you, check with the seller before you buy paste or a water tray. Peel and stick is obvious because of its separate liner.
Do WallWear wallpaper rolls need water or paste?
No. WallWear rolls are peel and stick, and the product pages state "No tools, paste, or soaking required." The adhesive is already on the back under a liner, so there is no water tray, no paste and no booking time involved. What the rolls do ask for is a clean, smooth, dry surface before you start.
