Different types of glue or paste for installing wallpaper and borders.

Aeration of Adhesives

Small holes caused by air bubbles in the adhesive on a strip of wallpaper, often created during the mixing process. It can lead to blistering of the wallpaper if not rectified.

All-over Design

The molding around doors, windows, and other openings in the wall.


The molding located at the bottom of a wall. Similar to the chair rail, the baseboard is meant to hide scuffs and markings from chairs, furniture, or shoes. Baseboards are also called skirting.

Batch Number

Blind Corner

A part of a room where mismatched wallpaper strips can easily be hidden, usually by large furniture objects.


A small bubble of air behind the wallpaper. Common causes of wallpaper blisters are aerated adhesives, improper application of paste or water or rest time after application, a room with a temperature less than 50 degrees Fahrenheit during the installation, and neglecting to prime porous walls prior to installation.


A bolt is one continuous roll of wallpaper equivalent to the length of two single rolls.


Once a strip of wallpaper is wetted (prepasted) or paste added (unpasted), it will typically be set down to rest in a gently folded position. This gives the adhesive time to activate before installation.


A narrow strip of wallpaper that is installed horizontally over the primary wallpaper. Usually borders are applied to the ceiling to hide uneven application of the vertical strips or to highlight certain aspects of the room. Borders can also be applied just above the baseboard or on either side of chair rails.

Border Spool

A wallpaper strip, usually narrower than a sidewall, installed horizontally in a room, to define, separate and accent areas of decoration. A coordinating border is often used to provide a finished edge where the sidewall meets the ceiling. It can also be used at chair rail height to separate one coordinating wallpaper from another, or as an architectural detail to create decorative panels in a room. By itself, on a painted wall, a border can be an inexpensive way to personalize a room or create a theme. Borders can refresh what’s already there or create a new look in little time. A border is packaged in a single spool of standardized length.

Border Spool Size

Widths of borders will vary but the length of a border spool is usually 15 Feet.


The term refers to how well water can pass through the wallpaper. While it typically refers to more industrial strength wallcoverings, some wallpapers, like fiberglass, are also breathable.

Chair or Dado Rail

Originally added to walls to reduce the amount of scraping and scratches from chairs against the wall, the chair rail is a molding installed at the average height of the tops of chairs. Today it provides an elegant look to rooms and offers a way to create two different looks, such as painting above the rail and wallpaper below it.

Colour Change

When manufacturers change the colors used for a particular pattern; the pattern remains the same, but the colors will be slightly different from the previous run.

Colour Run

The amount of a particular color and pattern a manufacturer produces until the color runs out. Each color run is different, even when the same colors are specified because the mixing process will never produce exactly the same color twice. There are slight variations between each color run.

The area of the wall between the baseboard and chair rail.

Dead Corner

Another term for kill point.

Double Cut

Double cutting is when wallpaper is overlapped during installation, then cut through both layers. This is usually done around doorways or wall borders, helping to hide the seams or when repairing a tear. The extra wallpaper is removed and the wall is wiped down to remove the remaining adhesive.

Double Roll (Bolt)

In the US, wallpaper is typically priced in single rolls, but sold in double rolls. The double roll is one long strip of wallpaper so that the roll is double the length of a single roll

Drop Match

A wallpaper with a drop match pattern creates a diagonal rather than a horizontal pattern sequence. To create the effect, every other strip will be identical. The strips in between will have the pattern dropped by half of the pattern length from the ceiling.


The length of the wallpaper made to fit a certain area. A strip that starts at the ceiling and goes to the floor is a full drop. If a strip runs from a chair rail to the floor it is a partial drop.

Dry Hanging

Another term for paste-the-wall application of wallpaper.

Dry Strippable

Wallpaper that can be removed without water or additional preparation.

Dye-lot Number (Batch Number)

Each batch of wallpaper produced in manufacturing during a single run is given a dye-lot number. When hanging wallpaper you want to ensure that you have the same dye-lot number for all of your rolls because there is usually a slight color variation between the different dye-lots. It is often obvious when two dye-lots were used within a room. It is also called a run number or batch number.

Easy Match

During the installation process, the wallpaper strips are matched using designated points. This makes the entire process far easier as you don’t have to guess about how to line up the patterns to create the desired effect. Once the wallpaper is hung, the points are removed with a damp sponge.

Another name for this kind of pattern is the random match pattern.

Fabric-backed Vinyl

Fabric-Backed Vinyl wallpapers have a fabric backing which makes them highly durable. Because of their ability to be bumped and scratched without being damaged, these are most commonly used for commercial jobs where high levels of durability are a must.

Gloss Paint

Gloss paint finishes are the most reflective paint finishes. Due to their reflective and more decorative nature, they are typically used on wood trim and molding. The high level of gloss also means they are the easiest to clean.


This particular type of wallpaper is popular because each pattern is unique. Grasscloth is handcrafted using entirely natural materials and gives a room a textured look that cannot be achieved by other kinds of wallpaper. The primary drawbacks are that they are difficult to clean, often requiring a professional cleaner if stains and smudges are not treated immediately, and they do not do well in humidity (grasscloths are discouraged for bathrooms and kitchens).

Half Drop

A drop match pattern that requires dropping the pattern half way down the repeat and aligning it with the ceiling line to keep the pattern consistent. Every other strip will be identically hung. The ones in between will be dropped half way down the repeat.

Kill Point

When installing wallpaper on all 4 walls of a room, the “kill point” is the place where the last strip is hung to join the first strip, finishing the project. This will usually result in an uneven pattern match at this point. We recommend hanging the first, and subsequently the last, strip in the least conspicuous area of the room to minimize the effect. This is often the corner behind you when you enter the room.

Latex Based Paint

Latex based paint is a water based paint made with synthetic acrylic binders. Excellent for painting over metal surfaces as they will prevent corrosion.

The term refers to where a pattern aligns, or matches, between strips. The type of match is usually indicated either on the website or on the roll information (in stores). Random match is the easiest to install and will not create any waste when measuring strips as these wallpapers line up randomly at the seams. Drop-match and straight match wallpaper may incur some waste as you have to start each strip at a certain point to ensure the pattern matches up at the seams.

Similar to modern stamps, peel and stick wallpaper can be installed directly from the roll without water or adhesive. To begin, remove a few inches of the backing material and slowly smooth the wallpaper onto the wall in a downwards motion, smoothing out the bubbles and other problems before pulling more of the backing from the strip. It is best used on flat walls. Since it is easy to install and remove, peel and stick wallpaper can be a good starting place for novices. However, it is not as durable as other types of wallpaper and will begin to peel from the wall sooner.


A blister in the wallpaper that is caused by a protrusion in the wall, such as drywall.

Plumb Line/Chalk Line

Before beginning to hang wallpaper, it is recommended that you draw a faint line with a level in the place where you plan to hang the first strip. The line is the plumb line, and it ensures that you hang the strip straight. You can also apply chalk to a string and snap it against the wall to create a plumb line.


When wallpaper already has the paste applied to the backing, it is called pre-pasted. This paste on this type of wallpaper is activated by dipping the wallpaper into water.
